Using the Snapshot Feature
Creating a Snapshot Virtual Disk
The
create snapshotVirtualDisk c
ommand provides three methods for
defining the physical disks for your snapshot repository virtual disk:
• Define each physical disk for the snapshot repository virtual disk by
enclosure ID and slot ID.
• Define a disk group in which the snapshot repository virtual disk resides.
Optionally define the capacity of the repository virtual disk.
• Define the number of physical disks, but not specific physical disks, for the
repository virtual disk.
When using the
create snapshotVirtualDisk
command to create a snapshot
virtual disk, the standard virtual disk name for the source virtual disk is the
minimum information required. When you provide only the standard virtual
disk name, the storage management software provides default values for the
other required property parameters for a snapshot virtual disk.
NOTE:
In some cases, depending on the host operating system and any virtual disk
manager software in use, the software prevents you from mapping the same host to
both a source virtual disk and its associated snapshot virtual disk.
An error message appears in the command line when the utility cannot
distinguish between the following:
• Source virtual disk and snapshot virtual disk (for example, if the snapshot
virtual disk has been removed)
• Standard virtual disk and virtual disk copy (for example, if the virtual disk
copy has been removed)
If you are running a Linux operating system, run the
hot_add
utility to
register the snapshot virtual disk with the host operating system.
NOTE:
The hot_add utility is not available for Windows.
