A customer has implemented an HP 3PAR StoreServ 7200 and needs to non-disruptively change the
RAID characteristic of a virtual volume. The customer must also change the disk tier where the
virtual volume resides. Which HP 3PAR command or software feature should the customer use to
accomplish this task?

A.
tunevv

B.
Adaptive Optimization

C.
Dynamic Optimization

D.
tunesys

Explanation:

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.
Incorrect:
: 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.
