NOTE: You can include a secondary virtual disk in a storage partition. However, any hosts that are mapped to the secondary virtual disk has read-only access until the virtual disk is promoted to a primary virtual disk, or the mirror relationship is removed. Storage partitioning topology is the collection of elements, such as Default Group, host groups, hosts, and host ports shown as nodes in the Topology pane of the Mappings tab in the AMW. For more information, see "Using the Mappings Tab" on page 94. If a storage partitioning topology is not defined, an informational dialog appears each time you select the Mappings tab. You must define the storage partitioning topology before you define the actual storage partition. Disk Group and Virtual Disk Expansion Adding free capacity to a disk group is achieved by adding unconfigured capacity on the array to the disk group. Data is accessible on disk groups, virtual disks, and physical disks throughout the entire modification operation. The additional free capacity can then be used to perform a virtual disk expansion on a standard or snapshot repository virtual disk. Disk Group Expansion To add free capacity to a disk group: 1 In the AMW, select the Logical tab. 2 Select a disk group. 3 Select Disk Group Add Free Capacity (Physical Disks). The Add Free Capacity window is displayed. Based on the RAID level, and the enclosure loss protection of the current disk group, a list of unassigned physical disks appears. NOTE: If the RAID level of the disk group is RAID Level 5, or RAID Level 6, and the expansion enclosure has enclosure loss protection, Display only physical disks that will ensure enclosure loss protection appears and is selected by default. 4 in the Available physical disks area, select physical disks up to the allowed maximum number of physical disks. NOTE: You cannot mix different media types or different interface types within a single disk group or virtual disk. Configuration: Disk Groups and Virtual Disks 137
