As far as I know, tunevv has always required a few additional parameters, perhaps you meant tunesys?
On my T800 running Inserv 2.3.1 MU4
ESFWT800-1 cli% help tunevv tunevv - Change the layout of a virtual volume.
SYNTAX The tunevv command uses one of the following syntax conventions: tunevv usr_cpg <cpg> [options] <VV_name> tunevv snp_cpg <cpg> [options] <VV_name> tunevv restart [options] <VV_name> tunevv rollback [options] <VV_name>
SUBCOMMANDS usr_cpg <cpg> Moves the logical disks being used for user space to the specified CPG. snp_cpg <cpg> Moves the logical disks being used for snapshot space to the specified CPG. restart Restarts a tunevv command call that was previously interrupted because of component failure, or because of user initiated cancellation. This cannot be used on thinly provisioned virtual volumes. rollback Returns to a previously issued tunevv operation call that was interrupted. The canceltask command needs to run before the rollback. This cannot be used on thinly provisioned virtual volumes.
DESCRIPTION The tunevv command is used to change the properties of a virtual volume that was created with either the createvv or createtpvv command by associating it with a different CPG.
AUTHORITY Super, Edit
OPTIONS -f Forces the command. The command completes without prompting for confirmation.
-waittask Specifies that the command will wait for any created tasks to complete.
-dr Specifies that the command is a dry run and that no logical disks or virtual volumes are actually tuned.
The following option is used when the <usr_cpg> and <snp_cpg> subcommands are specified:
-cnt <count> Specifies the number of identical virtual volumes to tune using an integer from 1 through 999. If not specified, one virtual volume is tuned. If the '-cnt' option is specified, then the subcommands, "restart" and "rollback" are not permitted.
SPECIFIERS <VV_name> Specifies the name of the existing virtual volume.
NOTES Use of this command requires a Dynamic Optimization license. Contact your local 3PAR representative for information.
When canceling a tunevv command task, the canceltask command can return before a cancellation is completed. Therefore, resources reserved for the task might not be immediately available. This can prevent actions like restarting the canceled tunevv command task. Scripts should use the waittask command in order to ensure orderly completion of the tunevv command cancellation before taking other actions.
EXAMPLES In the following example, the logical disks used for user space are moved to CPG cpg_sn1.0_p for virtual volume nf_st_tp_22.0:
cli% tunevv usr_cpg cpg_sn1.0_p nf_st_tp_22.0 Task 999 started
