Create Read-Only Snapshot Virtual Disk
Description
This command creates a read-only snapshot virtual disk for the snapshot images of a base virtual disk. To
change a read-only snapshot virtual disk to a read/write virtual disk, use the set snapVirtualDisk
convertToReadWrite command.
NOTE: You cannot use this command for a snapshot image that is used in online virtual disk copy.
Syntax
create snapVirtualDisk userLabel="snapVirtualDiskName"
snapImageID="snapImageID" readOnly
Parameters
Parameter Description
userLabel The name that you want to give to a snapshot
virtual disk. Enclose the snapshot virtual disk name
in double quotation marks (" ").
snapImageID The alphanumeric identifier of a snapshot image
that you want to add to the new snapshot virtual
disk. The identifier of a snapshot image is
comprised of two parts:
• The name of the snapshot group.
• An identifier for the snapshot image in the
snapshot group.
The identifier for the snapshot image can be one of
these:
• An integer value that is the sequence number
of the snapshot in the snapshot group.
• NEWEST - Use this option when you want to
show the latest snapshot image created in the
snapshot group.
• OLDEST - Use this option when you want to
show the earliest snapshot image created in the
snapshot group.
Enclose the snapshot image name in double
quotation marks (" ").
readOnly This parameter sets the snapshot virtual disk to
read-only. This parameter is actually a Boolean;
however, in the context of this command, the
Boolean value is always TRUE.
NOTE: With the readOnly parameter,
snapshot virtual disks are not created.
