We recently installed nWorks into SCOM2012 and I'm noticing a number of errors being generated on my ESX1 4.1 hosts. The error is:
Alert Monitor: nworks vCenter: Host cannot connect to storage Alarm
Created: 5/21/2012 10:48:09 AM
This appears to be occurring on all of my hosts EXCEPT ONE...the one that I DON'T have the Equallogic MEM (Multipathing Extension Module) installed on. When I dig in and look at the paths, they all look correct with the green diamond and "active" next to it. There doesn't appear to be any actual disconnections and there's no degradation of connectivity.
In Manage Paths in vsphere client, it shows the path policy as "DELL_PSP_EQL_ROUTED". In PowerCLI, the path policy shows as "fixed".
So, I'm wondering if its possible that the MEM is making the pathing determinations without vcenter recognizing them as such and only noticing that a path has ceased to exist momentarily and generating the alert (then, since this is a "stateless" alert, it never changes back...), thus triggering the warnings in SCOM??
Thanks for any insight you may have,
