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 5 rebuilding will be processed automatically in the
background and the KISS-Stor 0/5 RAID subsystem will record its progress. If the
system is shut down or powered off abnormally, the KISS-Stor 0/5 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.
When replacing a disk drive, the new disk drive must be empty,
and must have the same capacity or larger, than the disk drive
which is being replaced.
The failure or removal of a single drive in a RAID 5 array will not
lead to failure of the array.
The failure or removal of a single drive in a RAID 0 array will lead
to loss of all data on the array and the entire array must be re-
initialized.
What when a RAID fails?
A RAID fail occures if one disk drive in a RAID 0 array fails, or two disk drives in a
RAID 5 array.
If one disk drive in a RAID 0 array fails, or two disk drives in a RAID 5 array, all
data on the array is lost and cannot be recovered. RAID failure results in all data
on the array being lost. Please create a new RAID, or call your technical support.
