Adaptec CI/O Management Software User's Guide 4 Complete your work with the array disks. Data I/O resumes automatically at the end of the pause period. Note: Do not replace a non-downed drive in a paused array. The proper procedure is to down the drive, and then replace it. Failure to do so may lead to data corruption. Verifying Array Integrity Use this operation to verify the integrity of redundant data stored on fault-tolerant (RAID 0/1, RAID 1, RAID 5) arrays. When you run this operation, Adaptec CI/O Management Software checks the array for miscompares and corrects parity errors automatically. A miscompare occurs when the parity information on a RAID 5 array does not match the user data or when some part of the data on a mirrored disk pair in a RAID 0/1 or RAID 1 array does not match. In Adaptec CI/O Management Software you can schedule the Verify operation to run later or schedule it to run at a regularly occurring interval. We recommend that you schedule a verification of all arrays at least once a week. See Setting Scheduling Options on page 8-2 for more information. Note: The Verify operation will run automatically on all fault-tolerant arrays when you boot up your system following a disorderly system shutdown. Disorderly means that the system shuts down in an irregular manner (for example, a power failure or a system lock-up). Follow these steps to verify the integrity of redundant array data: 1 Click to open the Storage Configuration window. 2 Right-click on the Array icon. 3 Select Verify from the drop-down menu. 4 Leave the autocorrect box checked so that any data parity or mirroring mismatches will be corrected automatically. 7-6

Verifying Array Integrity
Use this operation to verify the integrity of redundant data stored on
fault-tolerant (RAID 0/1, RAID 1, RAID 5) arrays. When you run
this operation, Adaptec CI/O Management Software checks the
array for miscompares and corrects parity errors automatically. A
miscompare
occurs when the parity information on a RAID 5 array
does not match the user data or when some part of the data on a
mirrored disk pair in a RAID 0/1 or RAID 1 array does not match.
In Adaptec CI/O Management Software you can schedule the Verify
operation to run later or schedule it to run at a regularly occurring
interval. We recommend that you schedule a verification of all
arrays at least once a week. See
Setting Scheduling Options
on
page 8-2 for more information.
Note:
The Verify operation will run automatically on all
fault-tolerant arrays when you boot up your system
following a disorderly system shutdown.
Disorderly
means
that the system shuts down in an irregular manner (for
example, a power failure or a system lock-up).
Follow these steps to verify the integrity of redundant array data:
