EXAMPLES
In the following example, the LDs used for user space are moved to CPG cpg_sn1.0_p for VV

Task 999 started
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 and the virtual volume is converted to a tpvv:
cli% tunevv usr_cpg cpg_sn1.0_p -tpvv nf_st_tp_22.0
Task 1000 started
NOTES
There is a limit on the amount of data that can be tuned in a tunevv command. This is equivalent
to ten 16TB virtual volumes. If this limit is exceeded, the command will be rejected.
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 such as 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. See Section (page 664) for details about using the
waittask command.
When the -tpvv or -full options for the usr_cpg subcommand are specified, the tune will
automatically rollback on a failure. These options do not support virtual volumes with remote copy.
These options will only convert virtual volumes using snapshots if the -keepvv option is used, but
the snapshots will reside in the virtual volume specified by the -keepvv option.
