Environment

Aria lifecycle manager 8.x

Cause

There is a null entry for the snapshot generated time in the database

Resolution

1.  Take a non-memory snapshot of Aria suite lifecycle manager appliance from vCenter.
   
   
2. Login to the SSH terminal of vRLCM appliance.
   
   
3. Access the psql (database client) prompt:
   
   psql -U postgres -h localhost -d vrlcm
   
   
4. Run the below command to update snapshotGeneratedTime in the vm_snapshot_inventory table:
   
   UPDATE vm_snapshot_inventory SET snapshotgeneratedtime='time' WHERE vmid IN ('ID can be obtained from the vrlcm log');

Note: Time should be mentioned in Epoch format.

Example: UPDATE vm_snapshot_inventory SET snapshotgeneratedtime=1708993027056 WHERE vmid IN ('xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxx');
