SCSI Hard Drives
Be aware of the following guidelines cautioning unsafe hot-plug hard drive replacement.
•
Do not remove a degraded drive if any other member of the array is offline (the online
LED is off). No other drive in the array can be hot-plugged without data loss. The
exception to this is the use of RAID 1+0 as a fault-tolerant configuration. In this case,
drives are mirrored in pairs. More than one drive can fail and be replaced as long as the
drive or drives they are mirroring are online.
•
Do not remove a degraded drive if any member of an array is missing (previously
removed and not yet replaced).
•
Do not remove a degraded drive if any member of an array is being rebuilt, unless the
drive being rebuilt has been configured as an online spare. The online LED for the drive
flashes green or amber, indicating that a replaced drive is being rebuilt from the data
stored on the other drives.
NOTE: An online spare drive does not activate and start rebuilding after a predictive failure alert
because the degraded drive is still online. The online spare activates only after a drive in the array
has failed.
