NOTES
The createvvcopy command can be issued multiple times. However, the HP 3PAR Storage
System allows only two active physical copy tasks to run concurrently. Any additional physical
copy tasks are queued, pending the completion of the active physical copy tasks.
Multiple physical copy operations can occur simultaneously. Host-initiated I/O operations and
those operations initiated by issuing the createvvcopy command are executed at the same
priority level. As a result, noticeable performance degradation from a host perspective can
be observed.
Issuing the createvvcopy command results in the creation of a temporary snapshot and, in
the case of r, a resynchronization (resync) snapshot.
The temporary and resynchronization snapshots cannot be deleted while the copy is in progress.
Upon completion of the copy, the temporary snapshot is automatically deleted if the s option
is not specified.
If the resynchronization snapshot is saved, it can later be manually deleted. If the
resynchronization snapshot is deleted, later resynchronization is not possible.
If the s option is not specified, the relationship between the destination volume and source
volume is not retained.
Issue the showvv command to verify that a virtual volume copy has been made.
Issue the showvv d command to display the number of blocks remaining to be copied.
If the source or destination are volume sets then the createvvcopy command creates
consistent group snapshots at the same point in time so that related structures on different
volumes in the group remain consistent.
On systems that support zero_detect, if destination volume is a TPVV, zero_detect policy is
enabled at start of physical copy. After physical copy completes, the policy is changed to
no_zero_detect, even when the destination TPVV had zero_detect policy enabled before the
start of physical copy operation.
When Thin Persistence license is present, createvvcopy command will reclaim allocated
space when zero blocks are written to the destination TPVV.
If the -pri option is not specified, the physical copy will start at the default priority. If the tunes
and host I/O are running, then it is recommended to start vvcopy with the default priority.
