RocketRAID 2310 Driver and Software Installation

Notes:

1. 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 2310 (4, 5, 6, 7, 8).

2. You cannot change an array to another type of array with a smaller capacity.

In some cases, a disk may need to be added to the RocketRAID 2310.

3. During the OCE/ORLM procedure, the redundancy level of the array will be

the lowest of the source and target arrays; e.g. if you ORLM a RAID 0 array

to a RAID 1 array, the array will be non-redundant until the procedure is

complete.

4. The OCE/ORLM process can be aborted and continued at later time.

However, you should always stop the transform progress from the RAID

Management software.

5. An unexpected system crash may result in data loss while performing OCE/

ORLM on an array.

8 - Misc. Array/Device Options

Device Management

The Device Management window provides configuration information about control-

lers (the RocketRAID 2310 and other HighPoint host adapters), channels and hard

disks.

To access the Device Management window, highlight the “Management” menu, and

select the “Device Management” function.

Changing Device Settings

Depending upon the hard disk in question, and support provided by the current

device driver, you can adjust settings for disk: Read Ahead, Write Cache, TCQ, and

NCQ. Each feature can be enabled or disabled individually.
