OCUM Core not collecting info from VSMs

Hello,

I've updated OCUM Core/DFM to 5.2R1 yesterday and it's not showing volume and LUN data from VSMs.

It shows data from cluster, nodes and even root vols. Is it the same bug from described on http://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=814072 ?

Thanks,

HI,

Please maintain the MTU at 1500. The BURT clearly indicates that there are issues in discovery with non default MTU size.

If the MTU is different than 1500 then set it back to 1500 and see if the issue goes off.

If not, Could you check in /opt/NTAPdfm/dfmmonitor.log for any discovery errors or issues.  Could you paste here if any.

Thanks,

  Arun

So, I believe it's the MTU size since DFM isn't finding LIF status. I'll change it and let you guys know.

Thanks!

Hi,

Please set the MTU to 1500 and then do the discovery. Please let us know if you are seeing issues even after that.

Thanks,

Arun

Hi there,

I double checked all interfaces with role configured as data and if_groups and all is set to 1500. Only cluster interfaces are set to 9000.

Very good - the cluster_mgmt is 1500 MTU, so if the network and UM server are also set to 1500 then 814072 is not cause of your problem.

You should consider opening a support case.

Thanks,

Kevin

OK, I'm gonna open a case right now.

Thank you guys!

This bug will be to blame for UM 5.x Cluster-Mode monitoring issues when any of the network interfaces between (and including) the UM server to the cluster management LIF have an MTU other than 1500.

Thanks,

Kevin
