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.
