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. Check 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 in the menu, 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.
Migrating RAID Level or Stripe Size
Performance may be degraded slightly during migration, depending on the Expand
(or Rebuild) Priority setting. To minimize any effect, migrate during periods of low
server use.
NOTE: The migration 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 will be queued.
1. Back up all data on the logical drive. Although migration is unlikely to cause
data loss, observing this precaution provides extra security.
2. Check that the array accelerator batteries (if present) are fully charged.
3. In the Logical Configuration View panel, select the logical drive that you want
to migrate and then press the Enter key.
4. Select Drive Settings, and then press the Enter key.
