3.3.2 How to Add and Register a Disk Device Group (Solstice DiskSuite)

Disk device groups map directly to Solstice DiskSuite disksets. When you create a diskset using metaset(1M), you also create the disk device group with the same name and register it as a Sun Cluster disk device group.

1. Become superuser on the node connected to the disks where you want to create the diskset.

2. Use metaset to add the Solstice DiskSuite diskset and register it as a disk device group with Sun Cluster.

   # metaset -s diskset -a -h node-list

   -s diskset

   Specifies the diskset to be created.

   -a -h node-list

   Adds the list of nodes that can master the diskset.

3. Verify that the disk device group has been added.

   The disk device group name will match the diskset name specified with metaset.

   # scconf -p | egrep disk-device-group

3.3.2.1 Example--Adding a Solstice DiskSuite Disk Device Group

The following example shows the creation of the diskset and disk device group and verifies that the disk device group has been created.

# metaset -s dg-schost-1
# scconf -p | egrep dg-schost-1
Device group name: dg-schost-1
