InForm OS Version 2.3.1 Command Line Interface Reference

–halt

Specifies that an ongoing physical copy or snapshot promotion should be stopped.This will

cause the destination volume to be marked with the

cpf status, which will be cleaned up

when it is promoted to a base volume or when a new copy is started.

–s

Saves the snapshot of the source volume after the copy of the volume is completed. This

enables a fast copy for the next resynchronization. If not specified, the snapshot is deleted

and the association of the destination volume as a copy of the source volume is removed.

The

–s option is implied when the –r option is used and need not be explicitly specified.

–b

Specifies that this command blocks until the operation is completed. If not specified, the

createvvcopy command operation is started as a background task.

SPECIFIERS

<destination_volume | destination_volumeset>

Specifies the destination volume name or volume set name for the copy operation using up

to 31 characters in length. The volume set name must start with

set:.The destination

volume (or each member of the destination volume set) must be a writable base volume

(not a snapshot) of equal or greater size than a parent volume (if specified) and it must not

be exported as a VLUN.

RESTRICTIONS

■ The source and destination volumes must be writable.

■ The destination volume cannot be exported as a VLUN before or during the

createvvcopy command process.

■ The destination volume must be greater than or equal in size to the source volume.

■ If both the destination and source are volume sets then they must contain the same

number of members.

■ If the source is a volume set then the destination name can contain various patterns that

are used to form the copy volume name. See Help sub,

vvnamepat for details. Note that

the time/date related patterns are not supported in this command.

■ If the –s option is specified to save a snapshot for fast resynchronization and the snapshot

goes stale, the copy fails.
