Web RAID Management Interface
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) Highlight the desired RAID array
3) Click the "Maintenance" button.
Click the Verify button to start the verify process.
OCE/ORLM – modifying existing RAID arrays
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) Highlight the desired RAID array
3) Click the "Maintenance" button.
4) Select the target array type.
5) Click the "OCE/ORLM" button.
6) The OCE/ORLM page will appear. The interface is similar to the array creation
wizard:
A) When expanding a JBOD array, all the original disks must be included in the target
array, and these disks must be selected in the same order (as the original array). If you
want to migrate a JBOD array to another RAID level, only the first member disk can be
included in the target array. For example, a JBOD comprised of 3 disks (1, 2, 3), can only
be "migrated" using disk 1. Disks 2 and 3 cannot be used – disk 1 would have to be
combined with other disks attached to the RocketRAID card.
