Perform this procedure on each node of the cluster to configure internal hardware RAID disk mirroring to mirror the system disk. This procedure is optional.
Do not perform this procedure under either of the following circumstances:
Your servers do not support the mirroring of internal hard drives.
You have already established the cluster. Instead, perform Mirroring Internal Disks on Servers that Use Internal Hardware Disk Mirroring or Integrated Mirroring in Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS.
Ensure that the Solaris operating system and any necessary patches are installed.
Configure an internal mirror.
phys-schost# raidctl -c clt0d0 clt1d0
Creates the mirror of primary disk to the mirror disk. Enter the name of your primary disk as the first argument. Enter the name of the mirror disk as the second argument.
For specifics about how to configure your server's internal disk mirroring, refer to the documents that shipped with your server and the raidctl(1M) man page.
