Hello, I’ve 2 Exsi hosts ( V5.5) which are connected to one SAN. One host is offline now due to hardware issue and wondering how can obtain the images and rerun those in the online host.

If ALL the Virtual Machines (I think that';s what you may be calling images) are on the SAN, just browse the datastore and add those VMs to the Inventory and power them on.

They can't be in a cluster or you would see them already so the SAN must have host mappings / LUN masking set up so one host sees one datastore and the other sees a different one. We would have to know make/model of the SAN to tell you how to change the host presentation.

HI Andrew,

I am able to browse the data store and access the VM folders. There are many files such as .log, .nvram , .vmdk , .vmsd ..etc.

Could you please clarify below points.

1 ) Is there any option add VMs directly from current data location ?
2 ) Only .vmdk is required if need to create a new VM with a existing file ?

The files you are looking for are called VMX.

Select the file and right click and select Register/Add to Inventory.

if using vSphere Client see the following Articles, see step 6 below

HOW TO: Clone or Copy a virtual machine in VMware vSphere Hypervisor ESX/ESXi 4.x or ESXi 5.0

and also this one... because when you power on it could ask a question.

And no, there is no way to just add all VMs found and not in inventory yet, it is a manual process.
