False positives in OM

[keahey]

IHAC that is getting alerts that storage systems are down in OM, but they are not actually down.  Is there a bug that causes this or a setting that needs to be changed?

How far away are the systems from the OM server?  In my experience the further away they are (esp. network-wise) the more times you may see this as a failure in the network path can make it appear down.

Had a similar issue. Take a look at this bug http://now.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=383376 . Upgraded to 7.3.3 and fixed my

problem.

So is there a setting that we can increase to prevent this from happening then?

[mjgalloway]

The two options that NetApp gave was to either ignore the message or upgrade to 7.3.2P2 or higher. We upgraded to 7.3.3 which resolved the false alerts.

Hi  

       I dont think the burt you mentioned is the cause. Because this burt only cause false positive of power supply failed and not filer its self
