4.3 Starting and Stopping Tasks
Tasks are started when you:
• Create a redundant array.
• Transform an array.
• Restore an array.
• Check for consistency on redundant arrays.
• Verify a consistency bitmap (check_bitmap) on a redundant array.
The only type of task that you can stop without deleting the array is a con-
sistency check (CHECK).
The following types of tasks can be displayed for each array:
• TRANSFORM The TRANSFORM task is displayed while an array is
being transformed.
• CREATE The CREATE task is displayed while an array is being cre-
ated.
• CHECK The CHECK task is for redundant type arrays only. This task
is displayed while verifying that the parity (RAID5) or mirror drive
consistency is correct.
• RESTORE The RESTORE task is displayed while an array is being
restored.
• CHECK_BITMAP The CHECK_BITMAP task is displayed while
verifying that the parity on a RAID5 set, or the mirror halves on a
RAID1/10 set, are consistent. This action is performed automatically if
your system crashes.
• NOT_ACTIVE The NOT_ACTIVE task is displayed when no other
tasks are being performed.
