6 - Recovering/Verifying Arrays
When an array member (hard disk) of a redundant array fails, the array will be marked
as “broken”.
Broken arrays can be automatically rebuilt using hot-spare disks (see page 4-9).
However, if there are no available spare disks, you can still rebuild the array by
adding a new disk to it. To add a disk to a broken array:
1. Highlight the “Management” menu, and select the “Array Management”
function.
2. Highlight the broken array that needs to be rebuilt.
3. Click the Add Disk button on the toolbar or select “Add Disk” command from the
“Operation” menu.
4. If the disk is successfully added to the array, rebuild process will start
automatically.
Note: In some instances, a failed array will not rebuild automatically.
To manually start the rebuild process for a broken/critical array:
1. Highlight the “Management” menu, and select the “Array Management”
function.
2. Highlight the array that needs to be rebuilt.
3. Click the Rebuild button on the toolbar or select the “Rebuild” command from the
“Operation” menu.
Verifying an Array
For a RAID 1 or RAID 10 array, the verify process compares the data of one mirror
pair with the other (single hard disk in the case of RAID 1, and a paired set of disks
for RAID 10).
For RAID 5 and RAID 50, the verify process calculates RAID parity and compares it
to the parity data on the array. Verification checks each sector on a given disk.
Periodic verification of an array allows the disk drive firmware to take corrective
actions on problem areas on the disk, minimizing the occurrence of uncorrectable read
and write errors.
