Explanation

tunevv - Change the layout of a virtual volume. 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> Moves the logical disks being used for user space to the specified CPG. Moves the logical disks being used for snapshot space to the specified CPG. 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. 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 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. Not B: The HP 3PAR Data Optimization Software Suite v2 combines capabilities that provide autonomic storage tiering and dynamic data mobility with assured quality of service . Adaptive Optimization provides highly reliable, non-disruptive, cost-optimized storage tiering at the sub- volume level to deliver the right QoS to the right data at the right time on a large scale and Dynamic Optimization delivers it at the volume level. Best practice is to run Autonomic Rebalance (also known as tunesys) after adding drives.
