Replacing disks in hot-swap storage systems
In hot-swap storage systems configured with RAID 1+0, RAID 5, or RAID 6, a faulty or failed disk
can be removed and replaced with a new one. RAID will rebuild and the drive will return to Normal
status.
CAUTION: Before replacing a drive in a hot-swap storage system, always check the Safe to
Remove status in the CMC Disk Setup tab to verify that the drive can be removed without causing
RAID to go Off.
On the following storage systems, drive LEDs on individual disk drives also indicate whether the
drive can be removed safely. If the LED is off, the drive is safe to remove. If the LED is on, showing
solid white, removing the drive causes one or more of the logical drives to fail.
