We have a EMC Clarion CX4 san connected to several ESXi 5.1 hosts.
Following procedures in kb2004605 we have successfully unmounted, detached and physically unpresented luns from the esxi host.
There is only one 0B dummylun 0 connected to the esxi 5.1 host from this san at the moment.
We are going to remove the EMC Clarion CX4 san completely.
Should the dummylun 0 be detached from the esxi 5.1 host before we remove the Clarion san
or will this lun just disappear when the access to the san is removed from the esxi 5.1 hosts?
