4.8.2 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 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. To delete a virtual drive, follow these steps: Caution: Back up any data that you want to keep before you delete the virtual drive. 1. On the main WebBIOS CU screen, select a virtual drive. 2. Click Virtual Drives. 3. When the Virtual Drive screen appears, select Del in the lower left panel, and click Go. 4. When the message appears, confirm that you want to delete the virtual drive. 4.8.3 Importing or Clearing a Foreign Configuration 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. If WebBIOS CU detects a foreign configuration, the import screen appears, as shown in Figure 4.56. 4-88 WebBIOS Configuration Utility
