luns

A single LUN among from a group disappeared.

Neither the host nor the Vcenter can see it.

Four virtual machines on the LUN now are unknown.

The strange thing is the LUN is now available in the list when you try to ADD datastore from configuration ==> storage ==> Add Datastore

But this cannot help me since i need the vms on the lun and i do not get options to add the lun without formating it to VMFS

How can i get the lun back or atleast be able to copy the vms from it

Yes, I know running a virtual machine inside of a virtual machine is a bad idea. Yes, I know it will be very slow.

Eject disk on Mac Pro running VMWare ESXi

I'm almost embarrassed to ask this, but I'm stuck. I installed VMWare ESXi on a Mac Pro. It's working great! The problem is that you press F12 to eject the disk, and F12 is what you use to shutdown ESX. I can power down, open the case, pull out the CD drive and use a paper clip to force the drawer… >>> More
