Use the metaset command to create a Solaris Volume Manager disk set and register the disk set as an Oracle Solaris Cluster device group. When you register the disk set, the name that you assigned to the disk set is automatically assigned to the device group.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.
Caution - The name of the Oracle Solaris Cluster device group that you create (Solaris Volume Manage or raw-disk) must be the same as the name of the replicated device group.
To create a multi-owner disk group, use the –M option.
# metaset -s diskset –a –M –h nodelist
Specifies the disk set to be created.
Adds the list of nodes that can master the disk set.
Designates the disk group as multi-owner.
# cldevicegroup sync devicegroup
The device group name matches the disk set name that is specified with metaset.
# cldevicegroup list
# cldevice show | grep Device
Choose drives that are shared by the cluster nodes that will master or potentially master the disk set.
Use the full DID device name, which has the form /dev/did/rdsk/dN, when you add a drive to a disk set.
In the following example, the entries for DID device /dev/did/rdsk/d3 indicate that the drive is shared by phys-schost-1 and phys-schost-2.
=== DID Device Instances === DID Device Name: /dev/did/rdsk/d1 Full Device Path: phys-schost-1:/dev/rdsk/c0t0d0 DID Device Name: /dev/did/rdsk/d2 Full Device Path: phys-schost-1:/dev/rdsk/c0t6d0 DID Device Name: /dev/did/rdsk/d3 Full Device Path: phys-schost-1:/dev/rdsk/c1t1d0 Full Device Path: phys-schost-2:/dev/rdsk/c1t1d0 …
Use the full DID path name.
# metaset -s setname -a /dev/did/rdsk/dN
Specifies the disk set name, which is the same as the device group name.
Adds the drive to the disk set.
# metaset -s setname
# metaset -s dg-schost-1 -a -h phys-schost-1 # cldevicegroup list dg-schost-1 # metaset -s dg-schost-1 -a /dev/did/rdsk/d1 /dev/did/rdsk/d2
