Schedule Disk Tests

You can schedule SMART-based tests of the disk drives to be
periodically performed. Firmware on the disk drive will perform these
tests, and you can view the test results in the Repair/Rebuild screen.
See

Repair or Rebuild RAID Disks

(on page 299).

SMART tests can be performed while CC-SG is operational and in use.
They have a marginal impact on the CC-SG performance, but CC-SG
activities may significantly delay the completion of the SMART tests.
Therefore, it is recommended that you do not schedule frequent tests.

When scheduling SMART tests, be aware of these guidelines:

•

Only one test can be performed on a given drive at a time.

•

Another test will not be scheduled if a drive is currently under test.

•

If two tests are scheduled for the same time slot, the longer test
takes priority.

•

The test is performed "within" the hour specified, not necessarily at
the being of the hour.

•

Do not schedule SMART tests for periods of higher disk activity,
such as heavy CC-SG loads or vacuum operation that occurs every
day at midnight and noon.

Note: By default, CC-SG has a scheduled Short test that is performed at
2 AM every day and a scheduled Long test that is performed at 3 AM
every Sunday. These scheduled tests apply to both disk drives.

To change the Scheduling of Disk Tests:

1. Choose Operation > Utilities > Disk/RAID Utilities > Schedule Disk

Tests.
