1 Tune the snapshot space of the volume by issuing the tunealdvv -cpg <CPG_name>
<CPVV_name>
command, where:
 -cpg <CPG_name> is the name of the CPG to which the snapshot space is moved.
 <CPVV_name> is the CPVV you are re-laying out.
2 Tune the user space of the volume by issuing the
tunealdvv <CPVV_name> command.
 If your CPVV was created using the createvv command, perform the following to re-lay
out the volume:
1 Create a new CPG. See 7.10.2 Creating a Common Provisioning Group on page 7.12 for
instructions.
2 Tune the user space of the volume by issuing the
tunevv usr_cpg <CPG_name>
<CPVV_name>
command, where:
 usr_cpg <CPG_name> is the name of the CPG created previously in step 1, indicating
the user space of the new CPG will be used.
 <CPVV_name> is the CPVV you are re-laying out.
3 Tune the snapshot space of the volume by issuing the
tunevv snp_cpg <CPG_name>
<CPVV_name>
command.
 snp_cpg <CPG_name> indicates the CPG to where the snapshot space is moved.
 <CPVV_name> is the CPVV you are re-laying out.
NOTE: When using the tunealdvv command, it is recommended that in addition
to the options listed in the following procedure, the same options used during
volume creation, minus the
-cnt option, are also specified when tuning to
maintain consistency (RAID type, etc.) between the untuned and tuned volumes.
See the complete
tunealdvv command and option information available in the
InForm OS Command Line Interface Reference.
