3. To check the status of the RAID mirror, type the following command:
The preceding example indicates that the RAID mirror is still resynchronizing
with the backup drive.
The following example shows that the RAID mirror is synchronized and online.
The disk controller synchronizes IM volumes one at a time. If you create a second
IM volume before the first IM volume completes its synchronization, the first
volume’s RAID status will indicate SYNC, and the second volume’s RAID status
will indicate OPTIMAL. Once the first volume has completed, its RAID status
changes to OPTIMAL, and the second volume automatically starts synchronizing,
with a RAID status of SYNC.
Under RAID 1 (disk mirroring), all data is duplicated on both drives. If a disk
fails, replace it with a working drive and restore the mirror. For instructions, see
“Delete a Hardware RAID Volume” on page 25 .
For more information about the raidctl utility, see the raidctl(1M) man page.
