Chapter 3 Managing Disk Volumes 45
4. Create the RAID 1 volume:
The creation of the RAID volume is interactive, by default. For example:
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:
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.
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.
