PowerVault Modular Disk Storage Manager online help topics and the CLI
Guide.
Creating a Snapshot Virtual Disk Using the
Simple Path
You can choose the simple path to create a snapshot virtual disk if the disk
group of the source virtual disk has the required amount of free space. A
snapshot repository virtual disk requires a minimum of 8 MB free capacity.
The destination of a snapshot repository virtual disk is determined based on
the free capacity available in the disk group.
If 8 MB of free capacity is not available in the disk group of the source virtual
disk, the Create Snapshot Virtual Disks feature defaults to the advanced path.
For more information, see "Creating a Snapshot Virtual Disk Using the
Advanced Path" on page 162.
In the advanced path option, you can choose to place the snapshot repository
virtual disk in another disk group or you can use unconfigured capacity on the
storage array to create a new disk group.
About the Simple Path
Using the simple path, you can specify:
• 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.
• Snapshot Repository Virtual Disk Capacity—The snapshot repository
virtual disk capacity is expressed as a percentage of the source virtual disk
capacity (maximum 220 percent).
• Schedule—Creates the snapshot virtual disk at a specified time, or
according to a regularly occurring interval. If no schedule is specified, the
snapshot operation begins immediately. This parameter can also be used to
apply a schedule to an existing snapshot virtual disk.
