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.
Also, once the zone cluster is configured, switching ip-type between exclusive and shared is not supported.
This section contains the following procedures:
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:
Ensure that the Oracle Solaris OS is installed to support Oracle Solaris Cluster and Trusted Extensions software. See How to Install Oracle Solaris Software for more information about installing Oracle Solaris software to meet Oracle Solaris Cluster software requirements.
If an external name service is used, ensure that an LDAP naming service is configured for use by Trusted Extensions. See Chapter 5, Configuring LDAP for Trusted Extensions in Trusted Extensions Configuration and Administration
Review requirements and guidelines for Trusted Extensions in a zone cluster. See Guidelines for Trusted Extensions in a Zone Cluster.
Follow procedures in Chapter 3, Adding the Trusted Extensions Feature to Oracle Solaris in Trusted Extensions Configuration and Administration.
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
phys-schost# svcadm enable rlogin
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
# tncfg -t admin_low tncfg:admin_low> add host=ip-address1 tncfg:admin_low> add host=ip-address2 … tncfg:admin_low> exit
# tncfg -t admin_low remove host=0.0.0.0
# tncfg -t cipso tncfg:cipso> add host=ip-address1 tncfg:cipso> add host=ip-address2 … tncfg:cipso> exit
When all steps are completed on all global-cluster nodes, perform the remaining steps of this procedure on each node of the global cluster.
The LDAP server is used by the global zone and by the nodes of the zone cluster.
Next Steps
Create the zone cluster. Go to Creating a Zone Cluster.
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 4.3 System Administration Guide and the clzonecluster(1CL) man page.
Before You Begin
Create a global cluster. See Establishing the Global Cluster.
Read the guidelines and requirements for creating a zone cluster. See Zone Clusters.
If you plan to use a zone cluster configuration profile when creating a solaris or labeled brand zone cluster, ensure that the file is created and the file name has the .xml extension. See the Example section of the clzonecluster(1CL) man page for an example of the profile contents.
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 4.3 System Administration Guide.
Have available the following information:
The unique name to assign to the zone cluster.
The zone path that the nodes of the zone cluster will use. For more information, see the description of the zonepath property in Configurable Resources and Properties in Oracle Solaris Zones Configuration Resources. 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 management object that each zone-cluster node uses to connect to the public network. For a solaris10 branded exclusive-IP zone cluster, you can only use an IPMP group as the public network management object.
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.
You can also use Oracle Solaris Cluster Manager to create a zone cluster. For the browser interface log-in instructions, see How to Access Oracle Solaris Cluster Manager in Oracle Solaris Cluster 4.3 System Administration Guide.
You perform all steps of this procedure from a node of the global cluster.

You can also use Oracle Solaris Cluster Manager to view the capped-cpu memory configuration of a zone cluster, as well as the dedicated-CPU configuration. For the browser interface log-in instructions, see How to Access Oracle Solaris Cluster Manager in Oracle Solaris Cluster 4.3 System Administration Guide.
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:
|
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.
The results of your configuration change are displayed, similar to the following:

Installation of the zone cluster might take several minutes.
phys-schost# clzonecluster boot zone-cluster-name
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, and add the underlying public network interface to the IPMP group. Since the underlying interface might have addresses associated with it, you must move the associated addresses to the IPMP group.
In each of the nodes of the zone cluster, configure the IPMP group and add an underlying public network interface to it. Delete any address that is already associated with the underlying interface as shown in the output of the ipadm show-addr command, and create it back on the IPMP interface.
zcnode# ipadm create-ipmp -i interface sc_ipmp0 zcnode# ipadm show-addr interface zcnode# ipadm delete-addr interface/name zcnode# 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 (http://www.oracle.com/technetwork/documentation/solaris-cluster-33-192999.html).
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:
The solaris10 brand zone cluster provides a virtualized Oracle Solaris 10 cluster environment in an Oracle Solaris 11 configuration. You can use the solaris10 brand zone cluster to run or migrate cluster applications that are deployed on the Oracle Solaris 10 operating system, without any modification to the application.
Before You Begin
Perform the following tasks:
Ensure that all requirements in Planning the Oracle Solaris Cluster Environment are met.
Select a zone image to migrate or install. The target systems that can be used to create the zone image for installing a zone cluster are the following:
Native brand zone on an Oracle Solaris10 system.
Cluster brand zone on an Oracle Solaris Cluster node with proper patch level, archive derived from a physical system installed with Oracle Solaris 10 software. For patch information, see the Oracle Solaris Cluster 4 Compatibility Guide.
solaris10 brand zone archive derived from an installed solaris10 brand zone.
An Oracle Solaris 10 physical system.
An Oracle Solaris 10 physical cluster node.
For more information about solaris10 brand zones, see Creating and Using Oracle Solaris 10 Zones.
Perform all steps of this procedure from a node of the global cluster.
# flarcreate -S -n s10-system -L cpio /net/mysharehost/share/s10-system.flar This archiver format is NOT VALID for flash installation of ZFS root pool. This format is useful for installing the system image into a zone. Reissue command without -L option to produce an archive for root pool install. Full Flash Checking integrity... Integrity OK. Running precreation scripts... Precreation scripts done. Creating the archive... 6917057 blocks Archive creation complete. Running postcreation scripts... Postcreation scripts done. Running pre-exit scripts... Pre-exit scripts done.
For more information about creating archives, see Chapter 2, Assessing an Oracle Solaris 10 System and Creating an Archive in Creating and Using Oracle Solaris 10 Zones.
Create and configure the zone cluster on the global cluster, as shown in the following example.

Next Steps
The solaris10 brand zone cluster configuration is now complete. You can now install and bring up any Oracle Solaris 10 applications and make them highly available by creating the necessary resources and resource groups.
After you create a labeled brand zone cluster, perform the following steps to finish configuration to use Trusted Extensions.
Perform this step on each node of the zone cluster.
phys-schost# cat /etc/cluster/nodeid N
Ensure that the SMF service has been imported and all services are up before you log in.
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.

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
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.
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 11.3 Tunable Parameters Reference Manual.
