Create a set of copies for the volumes in set vvcopyset, keeping snapshots around for quick resynchronization: cli% createvvcopy -s -p set:vvcopyset set:copys Child Parent Status TaskID s1 foo started 14 s2 bar started 15 s3 baz queued 16 Resynchronize the volumes in the volume set copies: createvvcopy -r set:copies Child Parent Status TaskID s1 started 17 s2 started 18 s3 queued 19 Create a set of copies for the volumes in set vvcopyset, mapping the parent volumes to destination volumes with a pattern: cli% createvvcopy -p set:vvcopyset @vvname@-copy Child Parent Status TaskID foo-copy foo started 20 bar-copy bar started 21 baz-copy baz queued 22 Create an online copy of vv1 that is named vv2 which is fully-provisioned, using cpg1 as its user space and cpg2 as its snapshot space: cli% createvvcopy -p vv1 -online -snp_cpg cpg2 cpg1 vv2 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. 160 Create Commands
