Exchange 2007 VSS Lanfree backup not working

[johansen]

hi all,
I've a problem to backup our exchange 2007-ccr cluster via lanfree (VSS).
setup:
tsm5.5.3.0
storage agent 5.5.3.0
device driver 6.2.0.8
exchange is running on windows server 2008 64bit

As VSS backup is done via local dsm node I have red that you have to define "enablelanfree yes" in the baclient
dsm.opt file which we did, but still no lanfree backup.

the backup is started on the passive node (storage agent started):
tdpexcc backup SG_2 FULL /excserver=de02c001 /BACKUPMETHOD=VSS /FROMREPLICA /BACKUPDESTINATION=TSM /TSMOPTFILE=dsm.opt
and we have following output at the storage agent logging:

ANR0406I Session 19 started for node DE12K020 (WinNT) (Tcp/Ip DE12K020.europe.panorg.com(5147)).
ANR0408I Session 20 started for server TSM (AIX-RS/6000) (Tcp/Ip) for storage agent.

ANR0482W Session 2 for node TSM (AIX-RS/6000) terminated - idle for more than 15 minutes.
 
During exchange intergrity check this message is shown on the storage agent output and in activity log on the tsm server:
 
ANR0482W Session 19 for node DE02C001-TDP (Proxynode) terminated - idle for more than 15 minutes.
ANR0408I Session 23 started for server TSM (AIX-RS/6000) (Tcp/Ip) for event logging.

ANR0408I Session 25 started for server TSM (AIX-RS/6000) (Tcp/Ip) for storage agent.

.. backup starts but LAN usage there … so NO lanfree backup

and q session shows that there is no "proxy by storage agent" for the specific session.
Legacy backup is working LANFREE so no clue what could be the reason else than the msg above.


Does someone has an idea? We really need this to be working ...

Thanks a lot.

Does nobody has an answer to the issue?

I thought about extending the IDLETIMEOUT server settings which is 15minutes at the moment.
Maybe someone who has already a working setup (VSS lanfree backup) can tell me the idletimeout settings of their server?

 

[johansen]

I've set the IDLETIMEOUT and COMMTIMEOUT in the dsmsta.opt file and now the errors (session terminated) are gone, but there is still no lanfree backup when trying to backup VSS (doesn't matter if offloaded or online-vss backup).

legacy backup is working lanfree without any problems. Does no one else has seen such behavior before? There are no errors on client nor on server side.
... please help ...
