How Do I Cancel a Background Task That’s
Running on a Logical Drive?
One of the following tasks may be running in the background:
• Consistency Check
• Drive Initialization
• Redundancy Data Rebuild
You may wish to cancel a background task in order to boost disk array
performance in the short term, since the presence of a background task
usually degrades array performance to some degree. In most cases, however,
the task will need to be run to completion to restore the system to working
order.
 Caution
Be careful about canceling a background task,
because it may leave the logical drive in an unstable
state!
If you cancel a consistency check, you should be able to re-run it at a later
time without problems. This may not always be the case, however, if parity
errors were being corrected along the way.
If you cancel a drive initialization in midstream, you will be unable to use
that logical drive until the initialization is run to completion at a later time.
You may, however, continue to use other logical drives.
If you cancel a redundancy data rebuild, you may leave the logical drive in
an unstable state. It will remain in critical mode until you allow rebuild to
run to completion.
