A single LUN among from a group disappeared following the ESXI host restart. Neither the host nor the Vcenter can see it. I have four virtual machines on the LUN hiden now showing just unknown from VCenter.

Although strange I see the LUN available from the list you get when you try to ADD datastore from configuration ==> storage ==> Add Datastore.

I really need to mount the lun without formating since i have those four servers on it.

As an alternative being able to copy the files will do.


  • I have a LUN. I'm having a problem with it. I'm not going to tell you anything about it like where it resides and how I connect to it but I'm going to ask you to help me fix it. – joeqwerty Nov 11 '12 at 0:42
