HighPoint RocketRAID 2522 - Manual (Page 34)

RocketRAID 2522 Driver and Software Installation
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 RAID1, 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.
To verify an array:
1. Highlight the “Management” menu, and select the “Array Management” function.
2. Highlight the array you want to verify.
3. Click the Verify button on the toolbar or select the “Verify” command from the
“Operation” menu.
4. Verify process will start.
7 – OCE/ORLM
The RocketRAID 2522 supports both OCE (Online Capacity Expansion), and ORLM
(Online RAID Level Migration.
The RAID software provides support for these features through a single function,
known as OCE/ORLM.
With the OCE/ORLM function, you can transform an array from one RAID level to
another RAID level and/or resize the array dynamically, even under I/O load.
