Sharing SAN volumes within 2 ESXi hosts for High Availability


my understanding is that to configure high availability in a VMware ESXi environment, I will have to add the hosts to a cluster, enable vSphere HA on the cluster and share the SAN volume between the hosts.

My question is, do I have to manually map the SAN volume to all host  in the cluster, by specifying the iqn of the scsi connector (for each host in cluster) on the SAN? or is the volume sharing between host automatically done by just adding the host to the cluster?

You need to present all datastores to all hosts, before you start configuring your Cluster. (or enable HA and DRS).

It depends what SAN and SAN software you have with a NetApp Filer, you can present a single datastore to all hosts in the cluster at the same time, and it will do all the configuration for you.
