I have two DELL Poweredge 1950 as my ESX Hosts. They connect via HBA's to a 3TB SAN. I created a LUN on the SAN, made sure all four HBA cards were added as adapters. When I re-scan both servers, both of them pickup the new LUN as LUN ID 2, I goto add Storage to one server, its fine, picks it up, everything is good. I goto add it to the other server, the other server finds it and when I create it puts a (1) at the end and doesn't "share" it. When I goto create a VM to use that datastore, it throws up an error.
However, before I made the cluster, I created a LUN and was able to share it the same way described above fine.
I read somewhere to break the cluster and just create all the LUNs, however, since we are doing 1 LUN per server, it will get to the point of being unreasonable to break the cluster everytime we need to create a new server. Any ideas!?
