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 RAID 1, and a paired set of disks
for RAID 10).

For RAID 5, the verify process calculates RAID 5 parity and compares it to the parity
data on the array. Verification checks each sector on a given disk. Periodic verifica-
tion 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 2320 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.
