4. Create the RAID 1 volume:
# raidctl -c primary secondary
The creation of the RAID volume is interactive, by default. For example:
# raidctl -c c0t0d0 c0t1d0
Creating RAID volume c0t0d0 will destroy all data on member disks,
proceed
(yes/no)? yes
Volume 'c0t0d0' created
#
As an alternative, you can use the –f option to force the creation if you are sure of
the member disks, and sure that the data on both member disks can be lost. For
example:
# raidctl -f -c c0t0d0 c0t1d0
Volume 'c0t0d0' created
#
When you create a RAID mirror, the secondary drive (in this case, c0t1d0)
disappears from the Solaris device tree.
5. Check the status of a RAID mirror.
# raidctl

The RAID status might be OK, indicating that the RAID volume is online and fully
synchronized, but the volume also might be RESYNCING in the event that the data
between the primary and secondary member disks in an IM are still synchronizing.
The RAID status might also be DEGRADED, if a member disk is failed or otherwise
offline. Finally, it might be FAILED, indicating that volume should be deleted and
reinitialized. This failure can occur when any member disk in an IS volume is lost, or
when both disks are lost in an IM volume.
