14.2.10 Replacing a Failed Disk Drive
This section describes how to replace a failed disk drive among the disk drives that make up a RAID volume.
RAID0
If a disk drive in a RAID0 volume fails, all the data in the volume is lost. Replace the failed disk drive with a new disk drive of the same capacity, re-create the RAID0 volume, and restore the data from a backup.
RAID1/RAID10/RAID1E
Replace the failed disk drive with a new disk drive of the same capacity. Synchronization begins when the new disk drive is incorporated into the RAID volume.
Note - If two disk drives fail at the same time, the RAID volume enters the failed state (Failed).
Replace the failed disk drive, re-create the RAID volume, and then restore the data from backup.
In a hot spare configuration, the hot spare disk drive is automatically re-synchronized to restore data. Replace the faulty disk drive immediately without booting or rebooting Oracle Solaris or starting OpenBoot PROM.
Note - Follow this procedure to replace a faulty disk drive for any of the products listed in Table 14-12. Otherwise, if you replace the drive after booting or rebooting Oracle Solaris and starting OpenBoot PROM, the replacement disk drive will subsequently not function as a hot spare disk.
In this case, after replacing the faulty disk drive, delete the hot spare setting of the disk drive and create one again to enable recovery.
