Creating a Zone Cluster

This section provides procedures on how to use the clsetup utility to create a zone cluster, and add a network address, file system, ZFS storage pool, and storage device to the new zone cluster.

If any node is in noncluster mode, changes that you make are propagated when the node returns to cluster mode. Therefore, you can create a zone cluster even if some global-cluster nodes are in noncluster mode. When those nodes return to cluster mode, the system performs zone-cluster creation tasks on those nodes.

You can alternatively use the clzonecluster utility to create and configure a cluster. See the clzonecluster (1CL) man page for more information.


Note -  You cannot change the zone cluster name after the zone cluster is created.

This section contains the following procedures:

How to Install and Configure Trusted Extensions

This procedure prepares the global cluster to use the Trusted Extensions feature of Oracle Solaris with zone clusters. If you do not plan to enable Trusted Extensions, proceed to Creating a Zone Cluster.

Perform this procedure on each node in the global cluster.

Before You Begin

Perform the following tasks:

  1. Assume the root role on a node of the global cluster.
  2. Install and configure Trusted Extensions software.

    Follow procedures in Chapter 3, Adding the Trusted Extensions Feature to Oracle Solaris, in Trusted Extensions Configuration and Administration .

  3. Disable the Trusted Extensions zoneshare and zoneunshare scripts.

    The Trusted Extensions zoneshare and zoneunshare scripts support the ability to export home directories on the system. An Oracle Solaris Cluster configuration does not support this feature.

    Disable this feature by replacing each script with a symbolic link to the /bin/true utility.

    phys-schost# ln -s /usr/lib/zones/zoneshare /bin/true
    phys-schost# ln -s /usr/lib/zones/zoneunshare /bin/true
  4. Configure all logical-hostname and shared-IP addresses that are to be used in the zone cluster.

    See How to Create a Default Trusted Extensions System in Trusted Extensions Configuration and Administration .

  5. (Optional) Enable remote login by the LDAP server to the global-cluster node.
    1. In the /etc/default/login file, comment out the CONSOLE entry.
    2. Enable remote login.
      phys-schost# svcadm enable rlogin
    3. Modify the /etc/pam.conf file.

      Modify the account management entries by appending a Tab and typing allow_remote or allow_unlabeled respectively, as shown below.

      other   account requisite       pam_roles.so.1        Tab  allow_remote
      other   account required        pam_unix_account.so.1 Tab  allow_unlabeled
  6. Modify the admin_low template.
    1. Assign the admin_low template to each IP address that does not belong to a Trusted Extensions machine that is used by the global zone.
      # tncfg -t admin_low
      tncfg:admin_low> add host=ip-address1
      tncfg:admin_low> add host=ip-address2
      …
      tncfg:admin_low> exit
    2. Remove the wildcard address 0.0.0.0/32 from the tncfg template.
      # tncfg -t admin_low remove host=0.0.0.0
  7. Assign the cipso template to each IP address that does belong to a Trusted Extensions machine that is used by the global zone.
    # tncfg -t cipso
    tncfg:cipso> add host=ip-address1
    tncfg:cipso> add host=ip-address2
    …
    tncfg:cipso> exit
  8. Repeat Step 1 through Step 7 on each remaining node of the global cluster.

    When all steps are completed on all global-cluster nodes, perform the remaining steps of this procedure on each node of the global cluster.

  9. On each global-cluster node, add the IP address of the Trusted Extensions-enabled LDAP server to the /etc/inet/hosts file.

    The LDAP server is used by the global zone and by the nodes of the zone cluster.

  10. (Optional) Make the global-cluster node an LDAP client.

    See Make the Global Zone an LDAP Client in Trusted Extensions in Trusted Extensions Configuration and Administration .

  11. Add Trusted Extensions users.

    See Creating Roles and Users in Trusted Extensions in Trusted Extensions Configuration and Administration .

Next Steps

Create the zone cluster. Go to Creating a Zone Cluster.

How to Create a Zone Cluster (clsetup)

Perform this procedure to create a zone cluster using the clsetup utility.

To modify the zone cluster after it is installed, see Performing Zone Cluster Administrative Tasks in Oracle Solaris Cluster System Administration Guide and the clzonecluster (1CL) man page.


Note -  You cannot change the zone cluster name after the zone cluster is created.

Before You Begin

  • Create a global cluster. See Chapter 3, Establishing the Global Cluster.

  • Read the guidelines and requirements for creating a zone cluster. See Zone Clusters.

  • If the zone cluster will use Trusted Extensions, ensure that you have installed, configured, and enabled Trusted Extensions as described in How to Install and Configure Trusted Extensions.

  • If the cluster does not have sufficient subnets available to add a zone cluster, you must modify the private IP address range to provide the needed subnets. For more information, see How to Change the Private Network Address or Address Range of an Existing Cluster in Oracle Solaris Cluster System Administration Guide .

  • Have available the following information:

    • The unique name to assign to the zone cluster.


      Note -  If Trusted Extensions is enabled, the zone cluster name must be the same name as a Trusted Extensions security label that has the security levels that you want to assign to the zone cluster. Create a separate zone cluster for each Trusted Extensions security label that you want to use.
    • The zone path that the nodes of the zone cluster will use. For more information, see the description of the zonepath property in Resource Types and Properties in Introduction to Oracle Solaris Zones . By default, whole-root zones are created.

    • The name of each node in the global cluster on which to create a zone-cluster node.

    • The zone public hostname, or host alias, that you assign to each zone-cluster node.

    • If applicable, the public-network IP address that each zone-cluster node uses. Specifying an IP address and NIC for each zone cluster node is required if the zone cluster will be used in a Geographic Edition configuration. Otherwise, this requirement is optional. For more information about this Geographic Edition requirement, see Geographic Edition.

    • If applicable, the name of the public-network IPMP group that each zone-cluster node uses to connect to the public network.


    Note -  If you do not configure an IP address for each zone cluster node, two things will occur:
    • That specific zone cluster will not be able to configure NAS devices for use in the zone cluster. The cluster uses the IP address of the zone cluster node when communicating with the NAS device, so not having an IP address prevents cluster support for fencing NAS devices.

    • The cluster software will activate any Logical Host IP address on any NIC.



Tip  -  While in the clsetup utility, you can press the < key to return to a previous screen.

You can also use the Oracle Solaris Cluster Manager GUI to create a zone cluster. For GUI log-in instructions, see How to Access Oracle Solaris Cluster Manager in Oracle Solaris Cluster System Administration Guide .

  1. Assume the root role on an active member node of a global cluster.

    You perform all steps of this procedure from a node of the global cluster.

  2. Ensure that the node of the global cluster is in cluster mode.
    phys-schost# clnode status
    === Cluster Nodes ===
    
    --- Node Status ---
    
    Node Name                                       Status
    ---------                                       ------
    phys-schost-2                                   Online
    phys-schost-1                                   Online
  3. Start the clsetup utility.
    phys-schost# clsetup

    The Main Menu is displayed.

  4. Choose the Zone Cluster menu item.
  5. Choose the Create a Zone Cluster menu item.
  6. Type the name of the zone cluster you want to add.

    A zone cluster name can contain ASCII letters (a-z and A-Z), numbers, a dash, or an underscore. The maximum length of the name is 20 characters.

  7. Choose the property you want to change.

    You can set the following properties:

    Property
    Description
    zonepath=zone-cluster-node-path
    Specifies the path to the zone cluster node. For example, /zones/sczone.
    brand=brand-type
    Specifies the solaris, solaris10, or labeled zones brand used in the zone cluster.

    Note -  To use Trusted Extensions, you must use only the labeled brand. To create an exclusive-IP zone cluster, you must use only the solaris brand.

    To create an exclusive-IP solaris10 brand zone cluster, set the properties using the clzonecluster create command as follows:

    cz1> set brand=solaris10
    cz1> set ip-type=exclusive

    ip-type=value
    Specifies the type of network IP address used by the zone cluster. Valid ip-type values are shared and exclusive.
    The maximum number of exclusive-IP zone clusters is constrained by the cluster property num_xip_zoneclusters, which you can set during initial cluster installation. This value has a default of three. For more information, see the cluster (1CL) man page.
    enable_priv_net=value
    When set to true, Oracle Solaris Cluster private network communication is enabled between the nodes of the zone cluster. The Oracle Solaris Cluster private hostnames and IP addresses for the zone cluster nodes are automatically generated by the system. Private network communication is disabled if the value is set to false. The default value is true.
    When the enable_priv_net property is set to true along with the following properties, private communication occurs in the following ways:
    • ip-type=shared – Communication between zone cluster nodes uses the private networks of the global cluster.

    • ip-type=exclusive (solaris brand only) – Communication between zone cluster nodes uses the specified privnet resources. The privnet resources are either Virtual Network Interfaces (VNICs) for the Ethernet type of private network adapters, or InfiniBand (IB) partitions for the IB type of private network adapters. The VNICs or IB partitions are automatically created by the wizard over each private network adapter of the global cluster, and used to configure a zone cluster.

    The VNICs or IB partitions that the wizard generates use the following naming conventions:
    For the Ethernet type: private-network-interface-name_zone-cluster-name_vnic0.
    For the IB type: private-network-interface-name_zone-cluster-name_ibp0.
    For example, the private network interfaces of the global cluster are net2 and net3, and the zone cluster name is zone1. If net2 and net3 are Ethernet type network interfaces, the two VNICs that are created for the zone cluster will have the names net2_zone1_vnic0 and net3_zone1_vnic0.
    If net2 and net3 are IB type network interfaces, the two IB partitions created for the zone cluster will have the names net2_zone1_ibp0 and net3_zone1_ibp0.
  8. For a solaris10 brand zone cluster, enter a zone root password.

    A root account password is required for a solaris10 brand zone.

  9. (Optional) Choose the Zone System Resource Control property that you want to change.

    You can set the following properties:

    Property
    Description
    max-lwps=value
    Specifies the maximum number of lightweight processes (LWPs) simultaneously available to this zone cluster.
    max-shm-memory=value
    Specifies the maximum amount of shared memory in GBytes allowed for this zone cluster.
    max-shm-ids=value
    Specifies the maximum number of shared memory IDs allowed for this zone cluster.
    max-msg-ids=value
    Specifies the maximum number of message queue IDs allowed for this zone cluster.
    max-sem-ids=value
    Specifies the maximum number of semaphore IDs allowed for this zone cluster.
    cpu-shares=value
    Specifies the number of Fair Share Scheduler (FSS) shares to allocate to this zone cluster.
  10. (Optional) Choose the Zone CPU Resource Control property that you want to change.

    You can set the following properties:

    Property
    Description
    scope=scope-type
    Specifies whether the ncpus property used in a zone cluster is dedicated-cpu or capped-cpu.
    ncpus=value
    Specifies the limit for the scope type.
    • If the scope property is set to dedicated-cpu, the ncpus property sets a limit on the number of CPUs that should be assigned for this zone's exclusive use. The zone will create a pool and processor set when it boots. See the pooladm (1M) and poolcfg (1M) man pages for more information on resource pools.

    • If the scope property is set to capped-cpu, the ncpus property sets a limit on the amount of CPU time that can be used by a zone cluster. The unit used translates to the percentage of a single CPU that can be used by all user threads in a zone, expressed as a fraction (for example, .75) or a mixed number (whole number and fraction, for example, 1.25). An ncpus value of 1 means 100% of a CPU. See the pooladm (1M) , pooladm (1M) , and poolcfg (1M) man pages for more information on resource pools.

  11. (Optional) Choose the capped-memory property that you want to change.

    You can set the following properties:

    Property
    Description
    physical=value
    Specifies the GByte limit for physical memory.
    swap=value
    Specifies the GByte limit for swap memory.
    locked=value
    Specifies the GByte limit for locked memory.

    You can also use the Oracle Solaris Cluster Manager GUI to view the capped-cpu memory configuration of a zone cluster, as well as the dedicated-CPU configuration. For GUI log-in instructions, see How to Access Oracle Solaris Cluster Manager in Oracle Solaris Cluster System Administration Guide .

  12. Choose a physical host from the list of available physical hosts.

    You can select one or all of the available physical nodes (or hosts), and then configure one zone-cluster node at a time.

    You can set the following properties:

    Property
    Description
    hostname=hostname
    Specifies the zone-cluster node hostname. For example, zc-host-1.
    address=public-network-address
    Specifies the public network address for the zone-cluster node on a shared-IP type zone cluster. For example, 172.1.1.1.
    physical=physical-interface
    Specifies a network physical interface for the public network from the available network interfaces that are discovered on the physical nodes. For example, sc_ipmp0 or net0.
    defrouter=default-router
    Specifies the default router for the network address, if your zone is configured in a different subnet. Each zone or set of zones that uses a different defrouter setting must be on a different subnet, for example, 192.168.0.1. See the zonecfg (1M) man page for more information about the defrouter property.
  13. Specify the network addresses for the zone cluster.

    The network addresses can be used to configure a logical hostname or shared IP cluster resources in the zone cluster. The network address is in the zone cluster global scope.

  14. At the Review Configuration screen, press Return to continue and then type c to create the zone cluster.

    The results of your configuration change are displayed, similar to the following:

     >>> Result of the Creation for the Zone Cluster(sczone) <<<
    
    The zone cluster is being created with the following configuration
    
    /usr/cluster/bin/clzonecluster configure sczone
    create
    set brand=solaris
    set zonepath=/zones/sczone
    set ip-type=shared
    set enable_priv_net=true
    add capped-memory
    set physical=2G
    end
    add node
    set physical-host=phys-schost-1
    set hostname=zc-host-1
    add net
    set address=172.1.1.1
    set physical=net0
    end
    end
    add net
    set address=172.1.1.2
    end
    
    Zone cluster, zc2 has been created and configured successfully.
    
    Continue to install the zone cluster(yes/no) ?
  15. Type yes to continue.

    The clsetup utility performs a standard installation of a zone cluster and you cannot specify any options.

  16. When finished, exit the clsetup utility.
  17. Verify the zone cluster configuration.

    The verify subcommand checks for the availability of the specified resources. If the clzonecluster verify command succeeds, no output is displayed.

    phys-schost-1# clzonecluster verify zone-cluster-name
    phys-schost-1# clzonecluster status zone-cluster-name
    === Zone Clusters ===
    
    --- Zone Cluster Status ---

    ----      ---------   -------------   ------    -----------
    zone       basenode1     zone-1           Offline   Configured
                basenode2     zone-2           Offline   Configured
  18. For Trusted Extensions, make the password files writable on each zone-cluster node.

    From the global zone, launch the txzonemgr GUI.

    phys-schost# txzonemgr

    Select the global zone, then select the item, Configure per-zone name service.

  19. Install the zone cluster.
    phys-schost-1# clzonecluster install options zone-cluster-name
    Waiting for zone install commands to complete on all the nodes
    of the zone cluster "zone-cluster-name"...
    • For a solaris or labeled brand zone cluster, the following options are valid.
      Option
      Description
      -c config-profile.xml
      Includes system configuration information. The -c config-profile.xml option provides a configuration profile for all non-global zones of the zone cluster. Using this option changes only the hostname of the zone, which is unique for each zone in the zone cluster. All profiles must have a .xml extension.
      -M manifest.xml
      Specifies a custom Automated Installer manifest that you configure to install the necessary packages on all zone-cluster nodes. Use this option if the base global-cluster nodes for the zone-cluster are not all installed with the same Oracle Solaris Cluster packages but you do not want to change which packages are on the base nodes. If the clzonecluster install command is run without the –M option, zone-cluster installation fails on a base node if it is missing a package that is installed on the issuing base node.
    • For a solaris10 brand zone cluster, the following options are valid.

      Use either the –a or –d option to install Geographic Edition software, core packages, and agents that are supported in the zone cluster. Also, you can use the –d and –p options in the same command.


      Note -  For a list of agents that are currently supported in a solaris10 brand zone cluster, see Oracle Solaris Cluster 4 Compatibility Guide.
      Option
      Description
      Oracle Solaris Cluster patch 145333-15 for SPARC and 145334–15 for x86

      Note -  These patches are only required when you are installing the zone cluster with either the Oracle Solaris Cluster 3.3 software or the Oracle Solaris Cluster 3.3 5/11 software.

      You must install a minimum of Oracle Solaris Cluster 3.3 patch 145333–15 for SPARC or 145334–15 for x86 before you install the solaris10 brand zone cluster. Log in to My Oracle Support to retrieve the patch. Then from the global zone, use the –p option to install the patch. The patchdir directory is required, and must be accessible from inside the solaris10 brand zone on all nodes of the zone cluster.
      # clzonecluster install-cluster \
      -p patchdir=patchdir[,patchlistfile=filename] \
      [-n phys-schost-1[,…]] \
      [-v] \
      zone-cluster-name
      For additional instructions on installing patches, log in to My Oracle Support and search for ID 1278636.1, How to Find and Download any Revision of a Solaris Patch.
      -a absolute_path_to_archive zone-cluster-name
      Specifies the absolute path to an image archive to be used as the source image.
      # clzonecluster install \
      [-n nodename] \
      -a absolute_path_to_archive \
      zone-cluster-name
      -d dvd-image zone-cluster-name
      Specifies the full directory path to the root directory of an installed solaris10 non-global zone. The cluster software DVD directory must be accessible from the global zone of the node where you run the command.
      # clzonecluster install-cluster \
      -d dvd-image \
      zoneclustername

    For more information, see the clzonecluster (1CL) man page.

  20. If you did not use the -c config-profile.xml option when you installed the zone cluster, perform sysid configuration.

    Otherwise, skip to Step 26.


    Note -  In the following steps, the non-global zone zcnode and zone-cluster-name share the same name.
    • For an exclusive-IP labeled brand zone cluster , perform the following steps.

      Configure only one zone-cluster node at a time.

      1. Boot the non-global zone of one zone-cluster node.
        phys-schost# zoneadm -z zcnode boot
      2. Unconfigure the Oracle Solaris instance and reboot the zone.
        phys-schost# zlogin zcnode
        zcnode# sysconfig unconfigure
        zcnode# reboot

        The zlogin session terminates during the reboot.

      3. Issue the zlogin command and progress through the interactive screens.
        phys-schost# zlogin -C zcnode
      4. When finished, exit the zone console.

        For information about methods to exit from a non-global zone, see How to Exit a Non-Global Zone in Creating and Using Oracle Solaris Zones .

      5. From the global zone, halt the zone-cluster node.
        phys-schost# zoneadm -z zcnode halt
      6. Repeat the preceding steps for each remaining zone-cluster node.
    • For a shared-IP labeled brand zone cluster, perform the following steps on each zone-cluster node.
      1. From one global-cluster node, boot the zone cluster.
        phys-schost# clzonecluster boot zone-cluster-name
      2. Unconfigure the Oracle Solaris instance and reboot the zone.
        phys-schost# zlogin zcnode
        zcnode# sysconfig unconfigure
        zcnode# reboot

        The zlogin session terminates during the reboot.

      3. Issue the zlogin command and progress through the interactive screens.
        phys-schost# zlogin -C zcnode
      4. When finished, exit the zone console.

        For information about methods to exit from a non-global zone, see How to Exit a Non-Global Zone in Creating and Using Oracle Solaris Zones .

      5. Repeat Step b through Step d for each remaining zone-cluster node.
    • For a solaris or solaris10 brand zone cluster, perform the following steps on each zone-cluster node.
      1. From one global-cluster node, boot the zone cluster.
        phys-schost# clzonecluster boot zone-cluster-name
      2. Issue the zlogin command and progress through the interactive screens.
        phys-schost# zlogin -C zcnode
      3. When finished, exit the zone console.

        For information about methods to exit from a non-global zone, see How to Exit a Non-Global Zone in Creating and Using Oracle Solaris Zones .

      4. Repeat Step b through Step c for each remaining zone-cluster node.
  21. Boot the zone cluster

    Installation of the zone cluster might take several minutes.

    phys-schost# clzonecluster boot zone-cluster-name
  22. (Exclusive-IP zone clusters) Manually configure an IPMP group.

    The clsetup utility does not automatically configure IPMP groups for exclusive-IP zone clusters. You must create an IPMP group manually before you create a logical-hostname or shared-address resource.

    phys-schost# ipadm create-ipmp -i interface sc_ipmp0
    phys-schost# ipadm delete-addr interface/name
    phys-schost# ipadm create-addr -T static -a IPaddress/prefix sc_ipmp0/name

Next Steps

To configure Oracle Solaris Cluster 3.3 data services that you installed in a solaris10 brand zone cluster, follow procedures for zone clusters in the applicable data-service manual. See Oracle Solaris Cluster 3.3 Documentation.

To complete Trusted Extensions configuration, go to How to Configure a Zone Cluster to Use Trusted Extensions.

Otherwise, add file systems or storage devices to the zone cluster. See the following sections:

How to Configure a Zone Cluster to Use Trusted Extensions

After you create a labeled brand zone cluster, perform the following steps to finish configuration to use Trusted Extensions.

  1. Complete IP-address mappings for the zone cluster.

    Perform this step on each node of the zone cluster.

    1. From a node of the global cluster, display the node's ID.
      phys-schost# cat /etc/cluster/nodeid
      N
    2. Log in to a zone-cluster node on the same global-cluster node.

      Ensure that the SMF service has been imported and all services are up before you log in.

    3. Determine the IP addresses used by this zone-cluster node for the private interconnect.

      The cluster software automatically assigns these IP addresses when the cluster software configures a zone cluster.

      In the ifconfig -a output, locate the clprivnet0 logical interface that belongs to the zone cluster. The value for inetis the IP address that was assigned to support the use of the cluster private interconnect by this zone cluster.

      zc1# ifconfig -a
      lo0:3: flags=20010008c9<UP,LOOPBACK,RUNNING,NOARP,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1

      zone zc1
      inet 172.16.0.22 netmask fffffffc broadcast 172.16.0.23
    4. Add to the zone-cluster node's /etc/inet/hosts file the following addresses of the zone-cluster node.
      • The hostname for the private interconnect, which is clusternodeN-priv, where N is the global-cluster node ID

        172.16.0.22    clusternodeN-priv 
      • Each net resource that was specified to the clzonecluster command when you created the zone cluster

    5. Repeat on the remaining zone-cluster nodes.
  2. Authorize communication with zone-cluster components.

    Create new entries for the IP addresses used by zone-cluster components and assign each entry a CIPSO template. These IP addresses which exist in the zone-cluster node's /etc/inet/hosts file are as follows:

    • Each zone-cluster node private IP address

    • All cl_privnet IP addresses in the zone cluster

    • Each logical-hostname public IP address for the zone cluster

    • Each shared-address public IP address for the zone cluster

    phys-schost# tncfg -t cipso
    tncfg:cipso> add host=ipaddress1
    tncfg:cipso> add host=ipaddress2
    …
    tncfg:cipso> exit

    For more information about CIPSO templates, see How to Configure a Different Domain of Interpretation in Trusted Extensions Configuration and Administration .

  3. Set IP strict multihoming to weak.

    Perform the following commands on each node of the zone cluster.

    phys-schost# ipadm set-prop -p hostmodel=weak ipv4
    phys-schost# ipadm set-prop -p hostmodel=weak ipv6

    For more information about the hostmodel property, see hostmodel (ipv4 or ipv6) in Oracle Solaris 11.2 Tunable Parameters Reference Manual .
