Accusys ACS-76130 - Manual (Page 20)

Removing / replacing a drive
Swapping drives
The hot swap function is available on the RAID 5 array and can be operated during run time.
RAID rebuilding will be processed automatically in the background and the ACS-76130 RAID
subsystem will record its progress. If the host system is shut down or powered off abnormally,
the ACS-76130 RAID subsystem will continue the disk rebuilding process after power is
turned on again.
A hard disk should not be replaced when the system is turned off. Doing so
may leads to loss of data. Always hot swap disks in a RAID5 array.
What if a disk fails?
If a disk drive fails, or a key switch is turned off, the red disk activity indicator of its disk carrier
will light and the alarm will sound. When this happens, you can replace the failed SATA disk
with a new one, then turn the key switch on.
The failure or removal of a single drive in a RAID5 array will not lead to
failure of the array. The failure or removal of a single drive in a RAID0 array
will lead to loss of all data on the array and the entire array must be
re-initialized.
Removing a drive from a fixed connector drive carrier
1. Unlock the appropriate disk carrier. The red
disk activity indicator will light.
2. Slide the drive carrier out of its slot.
3. Slide the disk drive to the front of the carrier
so that the SATA connector is freed from
the drive carrier.
4. Lift out the disk drive.
