vCenter 5.1 List all Storage Devices with Only One Path

We have a large Vmware environemnt with 95 hosts and use Dell Foglist for performance monitor on top of vcenter alerts of course.  One the the items that bothers be in vCenter is there is not way to see all alerts / events from all host from one Window. Anyway I am looking for a way to search the entire datacenter and list all host with only one path to our SAN. Any thoughts or suggestions

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Dell Foglist he, he, that made me laugh, should that be Foglight!

We do this with Powershell/PowerCLI.....I've got a script somewhere, that runs a report...I could upload...

otherwise, you will have to look at all the LUNs, and Click Manage Paths for all LUNs, which takes a while.

Also it depends, on how you have your paths, e.g. dual pathed, quad pathed, becase the total number of paths is displayed....

so if you have 11 LUNs, and dual path, total paths is 22....quad...44

if it's odd, you've got a failed path..... but then you need to find it....and that's where PowerCLI comes in handy.

typical, try these, although I have an issue running them my PowerCLI seems duff at the moment!
