Adding Storage Devices to a Zone Cluster

This section describes how to add the direct use of global storage devices by a zone cluster. Global devices are devices that can be accessed by more than one node in the cluster, either one node at a time or multiple nodes concurrently.

After a device is added to a zone cluster, the device is visible only from within that zone cluster.

This section contains the following procedures:

ProcedureHow to Add an Individual Metadevice to a Zone Cluster (Solaris Volume Manager)

Perform this procedure to add an individual metadevice of a Solaris Volume Manager disk set to a zone cluster.

  1. Become superuser on a node of the global cluster that hosts the zone cluster.

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

  2. Identify the disk set that contains the metadevice to add to the zone cluster and determine whether it is online.


    phys-schost# cldevicegroup status

  3. If the disk set that you are adding is not online, bring it online.


    phys-schost# cldevicegroup online diskset

  4. Determine the set number that corresponds to the disk set to add.


    phys-schost# ls -l /dev/md/diskset
lrwxrwxrwx  1 root root  8 Jul 22 23:11 /dev/md/diskset -> shared/setnumber

  5. Add the metadevice for use by the zone cluster.

    You must use a separate add device session for each set match= entry.

    Note –

    An asterisk (*) is used as a wildcard character in the path name.


    phys-schost# clzonecluster configure zoneclustername
clzc:zoneclustername> add device
clzc:zoneclustername:device> set match=/dev/md/diskset/*dsk/metadevice
clzc:zoneclustername:device> end
clzc:zoneclustername> add device
clzc:zoneclustername:device> set match=/dev/md/shared/setnumber/*dsk/metadevice
clzc:zoneclustername:device> end
clzc:zoneclustername:> exit
    match=/dev/md/diskset/*dsk/metadevice

    Specifies the full logical device path of the metadevice

    match=/dev/md/shared/N/*dsk/metadevice

    Specifies the full physical device path of the disk set number

  6. Reboot the zone cluster.

    The change becomes effective after the zone cluster reboots.


    phys-schost# clzonecluster reboot zoneclustername
Example 6–7 Adding a Metadevice to a Zone Cluster

The following example adds the metadevice d1 in the disk set oraset to the sczone zone cluster. The set number of the disk set is 3.


phys-schost-1# clzonecluster configure sczone
clzc:sczone> add device
clzc:sczone:device> set match=/dev/md/oraset/*dsk/d1
clzc:sczone:device> end
clzc:sczone> add device
clzc:sczone:device> set match=/dev/md/shared/3/*dsk/d1
clzc:sczone:device> end
clzc:sczone:> exit

phys-schost-1# clzonecluster reboot sczone

ProcedureHow to Add a Disk Set to a Zone Cluster (Solaris Volume Manager)

Perform this procedure to add an entire Solaris Volume Manager disk set to a zone cluster.

  1. Become superuser on a node of the global cluster that hosts the zone cluster.

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

  2. Identify the disk set to add to the zone cluster and determine whether it is online.


    phys-schost# cldevicegroup status

  3. If the disk set that you are adding is not online, bring it online.


    phys-schost# cldevicegroup online diskset

  4. Determine the set number that corresponds to the disk set to add.


    phys-schost# ls -l /dev/md/diskset
lrwxrwxrwx  1 root root  8 Jul 22 23:11 /dev/md/diskset -> shared/setnumber

  5. Add the disk set for use by the zone cluster.

    You must use a separate add device session for each set match= entry.

    Note –

    An asterisk (*) is used as a wildcard character in the path name.


    phys-schost# clzonecluster configure zoneclustername
clzc:zoneclustername> add device
clzc:zoneclustername:device> set match=/dev/md/diskset/*dsk/*
clzc:zoneclustername:device> end
clzc:zoneclustername> add device
clzc:zoneclustername:device> set match=/dev/md/shared/setnumber/*dsk/*
clzc:zoneclustername:device> end
clzc:zoneclustername:> exit
    match=/dev/md/diskset/*dsk/*

    Specifies the full logical device path of the disk set

    match=/dev/md/shared/N/*dsk/*

    Specifies the full physical device path of the disk set number

  6. Reboot the zone cluster.

    The change becomes effective after the zone cluster reboots.


    phys-schost# clzonecluster reboot zoneclustername
Example 6–8 Adding a Disk Set to a Zone Cluster

The following example adds the disk set oraset to the sczone zone cluster. The set number of the disk set is 3.


phys-schost-1# clzonecluster configure sczone
clzc:sczone> add device
clzc:sczone:device> set match=/dev/md/oraset/*dsk/*
clzc:sczone:device> end
clzc:sczone> add device
clzc:sczone:device> set match=/dev/md/shared/3/*dsk/*
clzc:sczone:device> end
clzc:sczone:> exit

phys-schost-1# clzonecluster reboot sczone

ProcedureHow to Add a DID Device to a Zone Cluster

Perform this procedure to add a DID device to a zone cluster.

  1. Become superuser on a node of the global cluster that hosts the zone cluster.

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

  2. Identify the DID device to add to the zone cluster.

    The device you add must be connected to all nodes of the zone cluster.


    phys-schost# cldevice list -v

  3. Add the DID device for use by the zone cluster.

    Note –

    An asterisk (*) is used as a wildcard character in the path name.


    phys-schost# clzonecluster configure zoneclustername
clzc:zoneclustername> add device
clzc:zoneclustername:device> set match=/dev/did/*dsk/dNs*
clzc:zoneclustername:device> end
clzc:zoneclustername:> exit
    match=/dev/did/*dsk/dNs*

    Specifies the full device path of the DID device

  4. Reboot the zone cluster.

    The change becomes effective after the zone cluster reboots.


    phys-schost# clzonecluster reboot zoneclustername
Example 6–9 Adding a DID Device to a Zone Cluster

The following example adds the DID device d10 to the sczone zone cluster.


phys-schost-1# clzonecluster configure sczone
clzc:sczone> add device
clzc:sczone:device> set match=/dev/did/*dsk/d10s*
clzc:sczone:device> end
clzc:sczone:> exit

phys-schost-1# clzonecluster reboot sczone

ProcedureHow to Add a Raw-Disk Device to a Zone Cluster

  1. Use the zonecfg command to export raw-disk devices (cNtXdYsZ) to a zone-cluster node, as you normally would for other brands of non-global zones.

    Such devices would not be under the control of the clzonecluster command, but would be treated as local devices of the node. See How to Import Raw and Block Devices by Using zonecfg in System Administration Guide: Solaris Containers-Resource Management and Solaris Zonesfor more information about exporting raw-disk devices to a non-global zone.
