I need to determine which storage adapter that one of my ESXi hosts is booting from.

Is there a way through SSH or the GUI to tell this?

Did you install ESXi 5.0 onto local disk?

Select the volume properties of each VMFS datastore,

Under Storage > Right Click > Properties >> if you then look at the Right Hand Side (box) you will see the formatted partitions which exist for ESXi 5.0.

from there you will be able to see the storage device your ESXi 5.0 is installed and boots from.

The ESXI server boots from SAN and I have 131 LUNS mapped to it.

are you sure you are using ESXi ?

which LUN is set in the HBA BIOS? (at post!)

if you have that many LUNs, would it not be the smallest, and the LUN which is Mapped to a SINGLE HOST!

We're running version 5.  There is only ESXi

The hosts use to be ESX 4.1 with 50 GB boot volumes.  We migrated to 5 by unmapping the boot lun and creating a new 5 GB boot lun to install esxi 5 on.

I resolved it with VMWARE

It was the smallest lun.  The issue was that lun was being displayed as available to create a datastore from so it made me second guess whether I accidently picked one of the other LUNS that were mapped to the host.

Turns out ESXi uses very little space, so most of the 5 GB volume was still available.

I stated in my Post 38347029, "would it not be the smallest!"

You replied in your post, it was the smallest!
