HP 3PAR Command Line Interface Reference (OS 3.1.2 MU2) (QL226-97016, June 2013)

Disks that satisfy all of the specified characteristics are used. For example, -p -fc_gt 60
-fc_lt 230 -nd 2 specifies all the disks that have greater than 60 and less than 230 free
chunklets and that are connected to node 2 through their primary path.
–wait <secs>
If the tunealdvv command fails due to the lack of clean space, the -wait option specifies the
number of seconds to wait for the system to clean the dirty space before returning. If -wait 0 is
issued, the command returns immediately. If this option is not used, the command will keep waiting
for dirty chunklets to be cleaned if enough space will be available with the dirty chunklets cleaned.
–dr
Specifies that the command is a dry run and that no logical disks or virtual volumes are created.
–verbose on|off
Specifies that verbose output is either enabled (on) or disabled (off). If not specified, verbose is
disabled.
–cnt <number_of_VV>
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 -restart and
-rollback options and the restart and rollback subcommands are not permitted.
-restart
Restart a tunealdvv command call that was previously interrupted because of component failure,
or because of user-initiated cancellation. This option was deprecated in the 2.2.3 release and will
be changed or removed in a future release.
-rollback
Rollback a tunealdvv command call that was previously interrupted. The canceltask command
needs to run before the rollback. This option was deprecated in the 2.2.3 release and will be
changed or removed in a future release.
SPECIFIERS
<VV_name>
Specifies an existing virtual volume name.
RESTRICTIONS
• Access to all domains is required to run this command.
• This command requires a Dynamic Optimization license. Contact your local HP 3PAR
representative for information.
• This command requires sufficient available physical space, equivalent to the user size of the
volume being tuned.
• When changing the layout of a virtual volume, you can optionally apply arguments originally
defined for logical disk creation through the createtemplate command by issuing the
tunealdvv -templ <template_name> command. The -templ option is only valid for
logical disk template object types.
EXAMPLES
The following example shows how to use the tunealdvv command to convert a virtual volume
(testvol) to RAID-5:
cli% tunealdvv –t r5 testvol
Task 1 started.
tunealdvv 645
