We went through extensive DFM problems and had a long case running with Netapp after an upgrade of ONTAP from 6.4.2P6 to 6.5.1R1. Major SNMP problems with a large percentage of our qtrees not updating graphs, not sending alerts, sending them late etc.

On advice from NetApp, we upgraded to DFM 3.0. this didn't fix anything. We also tried disabling user quotas which disables XML info from the filers. Strangely enough, I accidentally "refreshed" DFM by deleting a couple of unused volumes on two filers. All of a sudden, they started reporting qtree, quota & alert info for many of those qtrees that were previously "broken". Still there were many not reporting.

We waited for a DFM 3.0.1 release and installed it. Restored XML and still no updating. 3.0.1 didn't appear do anything for us. Give it a try, you never know.

Another thing to note, the disaster recovery "tab" doesn't report snapmirror relationships where the snapmirror traffic is running through an alternate interface. i.e. client traffic on vif1 (e4 e11) and snapmirror on e0.

Are there any know issues w/ this version of DFM? We have run DFM 2.3 (older version) on 2 Windows 2000 systems successfully for over a year. We recently upgraded one system to DFM 3.0 and also built a new Windows 2000 server to run DFM 3.0 (fresh install) and we've been experiencing many performance issues. Specifically, the DFM alerting is severely degraded (e.g. alert notifications sent many hours late), and some of the core services are "not responding" on a regular basis (e.g. dfmMonitor, dfmWatchdog, dfmEvent). Our configurations have stayed the same and our existing DFM 2.3 system is functioning properly.

Any advice? Any known issues w/ DFM 3.0?
