Adding Disks to an 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 - Array”.
2) Click the Maintenance button.
3) Click the Add Disk button.
4) If the disk is successfully added to the array, rebuild process will start
automatically.
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.
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 5, verify process calculates RAID5 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 | Array”.
2) Click the Maintenance button.
3) Click the Verify button to start the verify process.
Rebuilding an Array
When a redundant array enters a critical/broken state, a rebuild is necessary to
restore the array’s redundancy (security). The rebuild process for an array generally
starts automatically. If you have aborted a rebuild process, you can start it manually.
To rebuild an array:
