PS6210 san and vmware 5.5 volume removal

have unmounted and detached a datastore in Vmware (KB2004605) from our 4 esxi 5.5 hosts.

If I look at managed paths  for the datastore ( starts with iscsi naa. number ) I assume the iscsi alias target number (iqn.2001-05.com.equallogic number) that matches the volume over on the Dell san manager screen is the volume I delete? Then go back over to vmware and rescan the hosts??
