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:
1. Select menu “Manage - Array”.
2. Click the “Maintenance” button.
3. Click the “Rebuild” button. The rebuild process should begin.
Expanding/Migrating an Array
With the OCE/ORLM function, you can migrate an array from one RAID level to another
RAID level and/or expand the array dynamically, even under I/O load. This function
implements both Online Capacity Expansion (OCE) and Online RAID Level Migration
(ORLM).
To expand/migrate an array:
1. Select “Manage - Array” from the menu.
2. Click the Maintenance button.
3. Select the target array type.
4. Click the OCE/ORLM button.
5. The OCE/ORLM page will appear. The interface is similar to the array creation
wizard.
