If you used SunPlex Manager to install Solstice DiskSuite software, do not perform this procedure. Instead, go to "Mirroring the Root Disk".
Perform this procedure on each node in the cluster.
Become superuser on the cluster node.
Create replicas on one or more local disks for each cluster node by using the metadb command.
See the metadb(1M) man page and your Solstice DiskSuite documentation for details.
To provide protection of metadevice state data, which is necessary to run Solstice DiskSuite software, create at least three replicas for each node. Also, you can place replicas on more than one disk to provide protection if one of the disks fails.
Verify the replicas.

Do you intend to mirror file systems on the root disk?
If yes, go to "Mirroring the Root Disk".
If no, go to "How to Create a Diskset" to create Solstice DiskSuite disksets.
The following example shows three metadevice state database replicas, each created on a different disk.
# metadb -af c0t0d0s7 c0t1d0s7 c1t0d0s7 # metadb flags first blk block count a u 16 1034 /dev/dsk/c0t0d0s7 a u 1050 1034 /dev/dsk/c0t1d0s7 a u 2084 1034 /dev/dsk/c1t0d0s7 |
