How to Enable a Zone to Run in a Failover Configuration

Before You Begin

Ensure that the /etc/netmasks file has IP-address subnet and netmask entries for all logical hostnames. If necessary, edit the /etc/netmasks file to add any missing entries.

1. Register the SUNW.HAStoragePlus resource type.

   # clresourcetype register SUNW.HAStoragePlus

2. Create a failover resource group.

   # clresourcegroup create solaris-zone-resource-group

3. Create a resource for the zone`s disk storage.
   • For non-global zones:

     This HAStoragePlus resource is for the zonepath. The file system must be a failover file system.

     # clresource create \
     -g solaris-zone-resource-group \
     -t SUNW.HAStoragePlus \
     -p Zpools=solaris-zone-instance-zpool \
     solaris-zone-has-resource-name

     Note -  This step applies to Oracle Solaris Kernel Zones only if the boot device is pointing to a zvol or if the suspend device is pointing to a path.

     ---

   • (OPTIONAL) For kernel zones:

     • Identify the devices to be used as boot storage and suspend storage for the kernel zone.

       node-1# cldev list -v d2
       DID Device     Full Device Path
       d2             node-1:/dev/rdsk/c0t60080E5000184744000005B4513DF1A8d0
       d2             node-2:/dev/rdsk/c0t60080E5000184744000005B4513DF1A8d0
       
       node-1# suriadm lookup-uri /dev/did/dsk/d2
       dev:did/dsk/d2
       
       node-1# cldev list -v d3
       DID Device       Full Device Path
       d3               node-1:/dev/rdsk/c0t60080E5000184744000005B6513DF1B2d0
       d3               node-2:/dev/rdsk/c0t60080E5000184744000005B6513DF1B2d0
       
       node-1# suriadm lookup-uri /dev/did/dsk/d3
       dev:did/dsk/d3
       
       d2 (suri=dev:did/dsk/d2) will be used for the kernel zone rpool as boot device
       
       d3 (suri=dev:did/dsk/d3) will be used as suspend device

     • (OPTIONAL)If you require device monitoring for the storage devices configured to be used by the kernel zone, configure a SUNW.HAStoragePlus resource and specify the corresponding global device group for the did devices identified in the previous step within the GlobalDevicePaths property.

       1. Register the SUNW.HAStoragePlus resource.

          node2# clrs create -t SUNW.HAStoragePlus -g zone-rg \
          -p GlobalDevicePaths=dsk/d2,dsk/d3 ha-zones-hasp-rs

       2. Set the resource name for that SUNW.HAStoragePlus resource within the HAS_RS variable to ensure the required resource dependency gets set up for the sczbt component. For example:

          HAS_RS=ha-zones-hasp-rs

4. (Optional) Create a resource for the zone's logical hostname.

   # clreslogicalhostname create \
   -g solaris-zone-resource-group \
   -h solaris-zone-logical-hostname \
   solaris-zone-logical-hostname-resource-name

5. Enable the failover resource group.

   # clresourcegroup online -M solaris-zone-resource-group
