Managing Configurations
This section includes information about maintaining and managing storage
configurations.
You should periodically run a consistency check on fault-tolerant virtual drives. A
consistency check verifies that the redundancy data is correct and available for RAID 1,
RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60 drive groups. To do this, follow these
steps:
1. On the main WebBIOS CU screen, select a virtual drive.
2. Click Virtual Drives.
3. When the Virtual Drive screen appears, select CC in the lower left panel, and click
Go.
The consistency check begins.
If the WebBIOS CU finds 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 might be corrupted.
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 configurable drive groups where
there is a space to configure. If multiple virtual drives are defined on a single drive
group, you can delete a virtual drive without deleting the whole drive group.
CAUTION: Back up any data that you want to keep before you delete the virtual drive.
To delete a virtual drive, follow these steps.
1. Access the Virtual Drive screen by clicking on a virtual drive icon in the right panel
on the WebBIOS CU main screen.
The Virtual Drive screen appears.
2. Select Delete in the bottom panel under the heading Operations, and click Go.
3. When the message appears, confirm that you want to delete the virtual drive.
A foreign configuration is a storage configuration that already exists on a replacement
set of drives that you install in a computer system.
In addition, if one or more drives are removed from a configuration, by a cable pull or
drive removal, for example, the configuration on those drives is considered a foreign
configuration by the RAID controller.
The BIOS CU allows you to import the foreign configuration to the RAID controller, or to
clear the configuration so you can create a new configuration using these drives.
NOTE: When you create a new configuration, the WebBIOS CU shows only the
unconfigured drives. Drives that have existing configurations, including foreign
configurations, will not appear. To use drives with existing configurations, you must first
clear the configuration on those drives.
