SAN Transport on Dell Equalogic / SAN
I have two SAN environments (HP lefthand and Dell Equalogic). The HP allows us to present a LUN to one server as read only while still allowing read / write access to another server but the Dell does not appear to do so.
How do you typically manage these LUNs to be SURE that no one goes in and mounts these "drives" in windows and destroys your VM infrastructure? Do you know of another way other than to set the drives as read only on the backup server?
What if the backup server did mount these drives - how would you restore the VM servers? Would you just be able to create a new LUN and somehow get the data to the new LUN and present to to VMware or would you literally have to do VMDK restores to the Vcenter server on the new LUN?
