How to change retion priority on MSA2040 snapshots

HanCas — Thu, 27 Jun 2019 08:15:37 GMT

Hello,

A customer cannot delete some old snapshots. When checking the log file I see this for the status of snapshots
A VSS170828204859249 2017-08-28 21:47:01 Available N/A Pool_A_CSV01 Pool_A_CSV01 0 8 N/A 376.9GB 212.1GB 164.8GB never-delete

This I see for multiple snapshot. So the setting most likely prevents the deletion of the snaps. How can I change this setting so I can delete the snapshots? I cannot find it in the documentation I have (SMU Guide)

From the details looks to me snapshot creation controlled by VSS provider which is outside of MSA and must be from some Windows System.

Coming to your query, you need to first change the limit-policy with the help of below command,

set snapshot-space limit-policy delete

You can also refer to CLI guide and page no 247 to check for command "set snapshot-space" to get more details,

You can verify the setting by running below command,

show snapshot-space

Then you can modify the retention priority of snapshots from volume level for each volume with the help of "set volume" command,

Hope this helps!

Thanks for the answer

We will issue the commands and delete the snapshots afterwards.
