I,m trying to add shared SAN storage to 2 ESX 3.5 hosts in preparation to setting up HA, DRS and Clustering. I'm doing this through VMInfrastructure Client 2.5 connecting to VMware Virtual Center Server2.5 I add the SAN storage (600GB, Target ID vmhba2:0:0, LUN 0)to vhost-1 using the name vsan-0. I format it with 8MB blocks maximizing the size. I then add the same storage (600GB, Target ID vmhba2:0:0, LUN 0) to vhost-2 using the name vsan-0. However while doing this I get a message that it is going to destroy the previously created partition. I continue using the same parameters as before. The procedure completes. When I go to Inventory-> Datastores I have 2 shared storage objects, wcc-vsan-0 and wcc-vsan-0 (1) Each of the datastores shows 1 Host connected. This is not shared properly. How can I get this 600GB SAN storage shared properly? I've been going through the VMware documentation but can find no specific procedure for this. What am I missing?? Thanks in advance JHP1
