Could you please share information on how to convert a TDVV volume to TPVV. (GUI and CLI)
Also, please let us know if it is a disruptive task and share points that need to be considered before performing this activity.
Thanks.

SolutionHello @mdan_06,
Hope your systems are on the latest 3PAR OS and SSMC (3.3.1 and 3.8)
To convert a vv from TDVV to TPVV (GUI):
Go to volumes and select the volume from the list
Actions -> Convert
Disable 'deduplicate' feature (Dedupe - No)
Click on 'Convert'.
To convert a vv from TDVV to TPVV (CLI):
Below is the command:
tunevv usr_cpg <cpg> [options] <VV_name>
Ex: tunevv usr_cpg Current_CPG -tpvv VV_Name
This is NOT a disruptive task.
Hope that helps.
Regards,
Srinivas Bhat

Re: Volume - TDVV to TPVV conversion
Available free storage.
It's been a few years since I looked at this, but as I recall, it makes a new VV. After all TDVV volumes are converted out of the CPG, the original volumes and the duplication backend store are deleted.
Since any snapshots of the original deduped volumes are not converted, if you have any you can clean up (delete) most or all of those.

Re: Volume - TDVV to TPVV conversion
Hello @mdan_06,
Converting the volume from TDVV to TPVV may occupy more physical space. You can check the present dedup ratio to understand how much more space the volume may occupy after converting it.
If you want to do a test run, you can clone or snap/restore one of the volumes and convert it for test purpose.
As Sheldon rightly mentioned, the snapshots before converting will not be relevant. Restoration from those snaps will result in TDVV only. So, after the volumes are converted to TPVV and become operational, you can cleanup older snapshots.

Srinivas Bhat
