HighPoint RocketRAID 2522 - Manual (Page 78)

Mac OSX Driver and RAID Management Software
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, 50), 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:
Select “Manage - Array” from the menu.
