does anybody know about the best Way to Upgrade HDLM on ESX Clusters?
My Plan would be:
1. Unmap all S-Vols to all Host in the ESX Cluster (we have all ESX WWNs in one Hostgroup)
2. Upgrade one Host after another
3. Map all S-Vols to all ESX Servers again
Would that be an appropriate way to do this? And what about point 2, do we have to uninstall the old version before installing the new one?
Actually we have 7.6.0 and want to upgrade to 8.1.0.
