Multiple dfpm_base snapshots on primary volume

kennyah2007 — Thu, 05 Jun 2025 06:27:50 GMT

We have several primary volumes which contain more then on dfpm_base snapshot. Following is output from the "snap list" command on the primary volume which shows two dfm_base snapshot. One dfm_base snapshot is current and the other is three days old:

tomcat # ssh fsxxxx snap list projxxxx

Volume projxxxx

Can someone please advice me on how we can clear up this issue with multiple dfm_base snapshots. We are using protection manger running under oncommand 5..0.1.

Thank you,

Hi Kenny,

What is the retention level specified in the policy? To get more details could you please run following commands and provide the output:

On the DFM server:

dfpm dataset list -x <Name_of_the_dataset_where_you_are_having_problems>

dfpm policy node get "<Name_of_the_protection_policy_associated_to_the_Dataset>" and

DFM diag

dfpm backup list <dataset_name_or_id>

And on the controller run:

snap list <The_primary_Volume_where_PM_Snapshots_are_not_getting_Deleted>

Regards,

-Amir

Hi Amirm,

I apologize for not having replied earlier. The protection manager system seems have to corrected the issue of two dfm_base snapshots on the primary volume. It looks as though there was a considerable amount of lag in the snapvault transfer from the primary to the secondary which was causing two dfm_base snaphosts to exist on the primary volume. The older dfm_base snapshot was removed once the snapvault transfer completed.

Thanks,

Kenny H
