2.2.6 Managing Configurations
This section includes information about maintaining and managing storage
configurations.
Running a Consistency Check
You should periodically run a consistency check on fault-tolerant virtual disks. 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 arrays. To do this, follow
these steps:
1. On the main WebBIOS CU screen, select a virtual disk.
2. When the Virtual Disk 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 array, 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 consistency data may be corrupted.
Deleting a Virtual Disk
You can delete any virtual disk on the controller if you want to reuse that space for
a new virtual disk. The WebBIOS CU provides a list of configurable arrays where
there is a space to configure. If multiple virtual disks are defined on a single array,
you can delete a virtual disk without deleting the whole array.
To delete a virtual disk, follow these steps:
Back up any data that you want to keep before you delete the virtual disk.
1. On the main WebBIOS CU screen, select a virtual disk.
2. When the Virtual Disk screen appears, select Del in the lower left panel, and
click Go.
3. When the message appears, confirm that you want to delete the virtual disk.
Importing or Clearing a Foreign Configuration
A foreign configuration is a storage configuration that already exists on a
replacement set of physical disks that you install in a computer system. In addition,
if one or more physical disks are removed from a configuration, by a cable pull or
physical disk removal, for example, the configuration on those disks is considered
a foreign configuration by the RAID controller.
