Virtual Disk Expansion Virtual disk expansion is a dynamic modification operation that increases the capacity of standard virtual disks. NOTE: Snapshot repository virtual disks can be expanded from the CLI or from MDSM. All other virtual disk types are expandable only from the CLI. If you receive a warning that the snapshot repository virtual disk is becoming full, you may expand the snapshot repository virtual disk from MDSM. See "Snapshot Repository Capacity" on page 146 for step-by-step instructions. Using Free Capacity You can increase the capacity of a virtual disk using the free capacity on the disk group of the standard virtual disk or the snapshot repository virtual disk. The Free Capacity node, shown in the Logical pane, is a contiguous region of unassigned capacity on a defined disk group. When increasing virtual disk capacity, some or all of the free capacity might be used to achieve the required final capacity. Data on the selected virtual disk remains accessible while the process for increasing virtual disk capacity is in progress. Using Unconfigured Capacity You can increase the capacity of a standard virtual disk or a snapshot repository virtual disk using the unconfigured capacity when no free capacity exists on a disk group. An increase is achieved by adding unconfigured capacity, in the form of unassigned physical disks, to the disk group of the standard virtual disk or the snapshot repository virtual disk. See "Disk Group Expansion" on page 128. For more information, see the PowerVault Modular Disk Storage Manager online help topics. Configuration: Disk Groups and Virtual Disks 129
