The RAID status might be OK, indicating that the RAID volume is online and fully
synchronized, but 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.
The Disk Status column displays the status of each physical disk. Each member disk
might be OK, indicating that it is online and functioning properly, or it might be
FAILED, MISSING, or otherwise OFFLINE, indicating that the disk has hardware or
configuration issues that need to be addressed.
For example, an IM with a secondary disk that has been removed from the chassis
appears as:
# raidctl

Volume
------------------------------------------------------
c0t0d0
See the raidctl(1M) man page for additional details regarding volume and disk
status.
Note – The logical device names might appear differently on your system,
depending on the number and type of add-on disk controllers installed.
