7-mode command to show 32-bit snapshots

Is there a 7-mode command (8.1.4) to show 32-bit snapshots?

 

I recently converted the aggregate to 64 bit, and the volume shows as upgraded to 64 bit. How do I identify which snapshots are 32 bit so that they can be deleted and thus can be 7mtt'd to a c-mode 8.3.2 cluster?

Give this a try: snap list -fs-block-format

 

You can append -V volname to narrow it to just the volume in question.  Comes in handy when trying to TDP SnapMirror a volume during cDOT migrations (which is of course what 7MTT does, we just do it manually).

Re: 7-mode command to show 32-bit snapshots

The ability to detect block format for Snapshots is added in 8.1.4p4 and 8.2.1. If you are running these or above versions, you can use the below command to find 32-bit Snapshtos:

 

volume snapshot show -fs-block-format !64-bit -fields fs-block-format

Thank you for your quick response.

 

Unfortunately I'm running 8.1.4P2 and the command doesn't work

 

I had looked for quite a long time and wasn't able to find a working command for 7-mode.

 

Hopefully this helps someone else

Re: 7-mode command to show 32-bit snapshots

The command for 7-Mode is as follows: snap list -fs-block-format <volume>.  However, as mentioned earlier, you need to be on at least 8.1.4P4 or 8.2.1.
