Configuring an Array 3. Alter the settings on this screen to suit your needs. 4. Press the Esc key to save the new configuration. 5. Exit CPQONLIN, and then restart the system to apply the changes. Expanding an Array Performance may be degraded slightly during array expansion, depending on the Expand Priority setting. To minimize any effect, expand the array during periods of low server use. NOTE: The expansion process takes about 15 minutes per gigabyte. The controller is not able to expand or migrate any other logical drive during this time. Instead, further requests for expansion or migration are queued. 1. Back up all data on the logical drive. Although array expansion is unlikely to cause data loss, observing this precaution provides extra security. 2. Verify that the array accelerator batteries (if present) are fully charged. 3. In the Logical Configuration View panel, select the array that you want to expand and then press the Enter key. 4. Select Expand and then press the Enter key. 5. Select the hard drive that you want to add to the array, and then press the Enter key. IMPORTANT: Do not assign a group of physical drives to the same array unless they are of the same capacity. If the drives have different capacities, the excess capacity of the larger drives cannot be used by the array and is wasted. 6. Repeat step 5 until you have finished adding drives. 7. Select Accept Changes and then press the Enter key. 8. Press the Esc key to begin the array expansion. You can see the progress of the expansion at any time by pressing the F3 key and then scrolling to the progress bar near the bottom of the screen.

Expanding an Array
Performance may be degraded slightly during array expansion, depending on the
Expand Priority
setting. To minimize any effect, expand the array during periods of
low server use.
NOTE:
The expansion process takes about 15 minutes per gigabyte. The controller is not able
to expand or migrate any other logical drive during this time. Instead, further requests for
expansion or migration are queued.
1.
Back up all data on the logical drive. Although array expansion is unlikely to
cause data loss, observing this precaution provides extra security.
2.
Verify that the array accelerator batteries (if present) are fully charged.
3.
In the
Logical Configuration View
panel, select the array that you want to
expand and then press the
Enter
key.

Select

Select the hard drive that you want to add to the array, and then press the

IMPORTANT:
Do not assign a group of physical drives to the same array unless they are
of the same capacity. If the drives have different capacities, the excess capacity of the
larger drives cannot be used by the array and is wasted.
