2.2.6 Managing Congurations
This section includes information about maintaining and managing storage
congurations.
Running a Consistency Check
You should periodically run a consistency check on fault-tolerant virtual drives. A
consistency check veries that the redundancy data is correct and available for
RAID 1, RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60 arrays. To do this, follow
these steps:
1. On the main WebBIOS CU screen, select a virtual drive.
2. When the Virtual Drive screen appears, select CC in the lower left panel, and
click Go.
3. Click Yes to continue. The consistency check begins.
If the WebBIOS CU nds a difference between the data and the parity value on
the redundant drive group, it assumes that the data is accurate and automatically
corrects the parity value. Be sure to back up the data before running a consistency
check if you think the data may be corrupted.
Deleting a Virtual Drive
You can delete any virtual drive on the controller if you want to reuse that space for
a new virtual drive. The WebBIOS CU provides a list of congurable drive groups
where there is a space to congure. If multiple virtual drives are dened on a single
drive group, you can delete a virtual drive without deleting the whole drive group.
Back up any data that you want to keep before you delete the virtual drive.
To delete a virtual drive, follow these steps:
1. On the main WebBIOS CU screen, select a virtual drive.
2. When the Virtual Drive screen appears, select Delete in the bottom panel
under the heading Operations, and click Go.
3. When the message appears, conrm that you want to delete the virtual drive.
