We are currently on version 5.1 of vCenter and ESXi. We have a DR test coming up for one of our applications which includes approx 12 VMs. My question is, when presenting the replicated LUNs to our DR / Test vSphere environment at our DR site, should we choose to resignature the LUNs? I thought I had read somewhere that in order for all hosts in a VMware cluster to see the LUN, it needs to be resignatured, as opposed to just mounting the LUN without resignaturing, which I believe can only be presented to one host when doing it this way. I just wanted to confirm whether or not this is correct.
Also, if resignaturing the LUN, will we need to manually update references for each VMs vmdk files, or is that done automatically?
When doing a DR test previously and just choosing to mount the LUN and not to resignature, the LUN was only visible on that one host which is in a three node cluster.
Thanks
