Hello,
There will be an upgrade from ESX vSphere 4.1 to Vsphere 5.0 on 2 ESX hosts. The upgrade will be done one by one.
The question raised by our change management team is : what is the manual way to allocate LUN storage while the ESX hosts are down for upgrade

Is there any way to present the LUNs to the VMs directly?

Thanks in advance,
Moinuddin Imam.

If you want to present LUNs directly to VMs, you would use a RAW (RDM) LUN.

But if the Hosts are down, the VMs would also be down, unless you move the VMs from the host to be patched, to another host.
