Creating a Snapshot Virtual Disk Using the Advanced Path

About the Advanced Path

Use the advanced path to choose whether to place the snapshot repository virtual disk on free capacity or unconfigured capacity and to change the snapshot repository virtual disk parameters. You can select the advanced path regardless of whether you use free capacity or unconfigured capacity for the snapshot virtual disk.

Using the advanced path, you can specify the following parameters for your snapshot virtual disk:

•Snapshot Virtual Disk Name—A user-specified name that helps you associate the snapshot virtual disk to its corresponding snapshot repository virtual disk and source virtual disk.

•Snapshot Repository Virtual Disk Name—A user-specified name that helps you associate the snapshot repository virtual disk to its corresponding snapshot virtual disk and source virtual disk.

•Capacity Allocation—This parameter allows you to choose where to create the snapshot repository virtual disk. You can allocate capacity by using one of the following methods:

–Use free capacity on the same disk group where the source virtual disk resides.

–Use free capacity on another disk group.

–Use unconfigured capacity and create a new disk group for the snapshot repository virtual disk.

–Dell recommends placing the snapshot repository virtual disk within the disk group of the source virtual disk. This ensures that if drives associated with the disk group are moved to another storage array, all the virtual disks associated with the snapshot virtual disk remain in the same group.

•Snapshot Repository Virtual Disk Capacity—The snapshot repository virtual disk capacity is expressed as a percentage of the source virtual disk capacity. The maximum percentage allowed is 120 percent.
