We are using SnapManager for Exchange for our Exchange mailbox´s. Every night I get following error, and get it for each lun sg01-sg08 (Exchange database). I get it when the snapmanager takes the snapshot, but why?
dfm: Warning event on faspri01:/sdw_cl_iscsi01_0/sg07/sg07 (LUN Offline)
A Warning event at 20 Mar 23:54 W. Europe Standard Time
on Lun Path sdw_cl_iscsi01_0/sg07/sg07 on Active/Active Controller

Do you do verification of your SnapManager for Exchange backups?
The sdw_cl_ prefix in the volume name indicates this is a SnapDrive Clone volume. I'd say SME is taking your backup snapshots then creating a flexclone to mount to a server for verification. Once verified the job will offline and destroy the flexclone, which generates the messages you are seeing in DFM. They can be safely ignored.

When I got the following error message "dfm: Warning event on faspri01:/sdw_cl_iscsi01_0/sg07/sg07 (LUN Offline)" it was associated with my Exchange backups. When using SnapManager for Exchange, you can choose SME to create a copy of the LUN and verify it.

I know this is an old discussion, but I was wondering if you were able to filter out the warnings from DFM regarding the sdw_cl* volumes and LUNs ?
It's a bit fustrating to recieve a warning email each time your servers are taking a backup/verify (it happens on both SMSQL and SME)...
So is there somewhere inside DFM where you can have it ignore any specific volumes, or maybe just clones all together?
