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 331).
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.
