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.
Verify 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.
5.
Change the RAID level or stripe size shown on this screen.
6.
Press the
Esc
key to accept the changes and begin migration.
You can check the progress of the migration at any time by pressing the
F3
key
and then scrolling to the progress bar near the bottom of the screen.
