I have a simple VMware infrastructure with 3 VM Hosts and 1 SAN at the back end. Hosts connect to SAN via SAS. I have a primary partition on the SAN that the hosts see/access and where all the VMs reside. Hosts run ESXi 5.5 (with latest updates) and my VMs are Win2012 R2.
I now want to create a second SAN partition and make it available to the Hosts/VMs. I created the partition and gave it a different LUN. However I cannot figure out how to have the hosts "see" it. I tried to create a new Datastore but there are no "available LUNs" to connect to. Am I doing something wrong? Could someone help?
