a deleted array will be inaccessible
Array Maintenance – Rebuilding/Verifying/Modifying RAID arrays
Rebuilding a Failed Array
When an array member in a redundant array fails, the array will be listed as broken. A
broken array will be automatically rebuilt using available-spare disks. However, if you
have no spare disks configured, you can still rebuild by manually adding an Available
Disk to the array. To add a disk to a broken array:
1) Select menu "Manage -
2) Highlight the desired RAID array
3) Click the "Maintenance" button.
4) Click the "Add Disk" button.
5) If the disk is successfully added to the array, rebuild process will start
automatically. A progress bar will be displayed.
Note: If the system utilizes hot-swap capable enclosures, you can add new physical
disks to the RocketRAID card in order to rebuild or modify an existing array, using the
"Rescan" feature.
Reminder: When adding disks manually, make sure to initialize the disk (see Preparing
Hard Disks).
Only initialized disks can be used to rebuild RAID arrays.
Verifying an Array
For a RAID 1 or RAID1/0 array, verify process compares the data of one mirror pair
with the other. For RAID 3, 5 and RAID 6, verify process calculates RAID parity and
compares it to the parity data on the array. Verification checks each sector on a drive.
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.
To verify an array:
1) Select menu "Manage -
