Verify esxi installation path? 1

[dodeesos]

We have a couple of esxi's in a cluster running from local sd cards.
One of them behaves a bit strange when it loses contact with our ip-SAN. The affected esxi disconnects from the cluster, i can access it by running the vsphere client directly against but the status of the vm's is grayed out...

I suspect it might be installed on the ip-SAN somewhere instead of on the sd card by mistake.

However, i cant find any way to verify the esxi installtion path.
The sd card dosent show up under datastore och datastore adapters in vsphere client. Not even on the esxi's where I know its de facto installed on a sd card.

Any clues?

In the vSphere client select Configuration > Storage. Select each Datastore and click Properties. If ESXi is installed on one of the LUNs you'll see a bunch of DOS partitions in the Extent Device listings.

Thanks cabraun and Dave.

However, I didnt find any esx installation so i guess its actually installed on sd card.

I also see that that my first post is a bit wrong.
We have this problem when the affected esx loses contact with our Fibre Channel SAN. Not when it loses contact with our IP SAN as I wrote.
And this happens even if at the time no powered on vm have storage in the FC SAN.

Now, i can check this theory of my trobleshootning list.

Another idea is that HA might be the cause, its shut of but some part of might be lurking around anyways... Who knows?

Thanks again!
Regards!
