About Self-tests
Two self-tests can be set, to check whether UDMA Mode can be upgraded,
and whether SMART thresholds have been exceeded.
Initially, these tests are set to run every 24 hours. You can change the schedule
for when they are run, and you can disable the tests, if you prefer not have to
have them performed. For more information, see “Selecting Self-tests to be
Performed” on page 180.
Setting Background Task Rate
In 3DM, you can set the relative performance of background tasks
(initializing, rebuilding, and verifying) in relation to normal I/O activity.
9000-series controllers show separate settings for Rebuild Rate and Verify
Rate. (Initialization occurs at the Rebuild rate.) 7000- and 8000-series
controllers show only one setting for Task Rate, which applies to both rebuild
and verify rates.
Rebuild and verify tasks can be started manually or scheduled. For details
about manually starting these processes, see “Rebuilding Units” on page 181
and “Verifying a Unit through 3DM” on page 187. For details about
scheduling rebuild, verify, and other tasks, see “Scheduling Background
Tasks” on page 176.
To change the background task rate
1
Choose
Management > Controller Settings
from the menu bar.
2
In the
Background Task Rate
section of the Controller Settings Page,
select one of the five radio buttons to indicate the relative task rate for
Rebuild and Verify Tasks.
The furthest left buttons set the firmware to the fastest rebuild and verify
settings. This means that maximum processing time will be given to
rebuilds or verifies rather than I/O. The furthest right buttons set the
firmware to the slowest rebuild and verify settings, giving maximum
processing time to I/O.
After you select one of the radio buttons, the page refreshes, and a
message at the top confirms the change you have made.
For more information about these settings, see the reference section,
“Controller Settings Page” on page 92.
