We are currently usuing version 5.1 of vCenter and ESXi. During a DR test yesterday, we mounted a replicated LUN to our VMware cluster at our DR site. I then chose to add the LUN. I was given the option to keep the signature or resignature the LUN. I chose to keep the existing signature. The LUN was mounted but only to one server in the cluster. Is it required to resignature the LUN in order for other servers in the cluster to see it? Or, do you need to add the LUN seperately on each host in the cluster?
