Does vCenter 2.5 indicate within GUI if a SAN path is down? Where/What does it look like?

We have a SAN storage switch reboot this weekend. The two storage switches will be rebooted in rotation. I haven't observed this in vCenter before ... do the paths in vCenter show down via an icon/alert when a path is lost? Where/What does it look like. I have no lab to test with and don't see a "health" or green status indicator on paths except in "manage paths" pop-up window and that is only on active path. Would I have to logon to each host and run Esxcfg-mpath with -a or -l -v and compare to prior to storage reboot output?

Does the "On" mean that it is UP/Functional?

esxcfg-mpath -l

There may be some indicator for vCenter 2.5 but I don't know. Maybe someone else does.

What I can say which may be useful to you is that the vSphere upgrade has far more alarm triggers built in, including storage related triggers. Page 247 of the Basic Admin Guide refers to a 'Host - Connection and mode' trigger which includes detection of lost storage path redundancy.

No it doesn't ... You have to inspect this manually...

What I've done is script a simple "dead path" detection and dropped it in the hourly cron.

The script would then send a SNMP trap to a monitoring servershowing a HBA change..

What about this???

Check SAN connectivity

Using vCenter

Choose an ESX Host | Configuration tab | right click storage | choose Properties

View Path Status - path will show "Dead" if offline (note: click "Manage Paths" to verify view of all Paths) - Do this for each storage path on each ESX host
