After installed REDHAT OS on a used to be ESX host, we still can see the old storage LUNs, in addtion to the new NetApp LUNs.
It could be caused by the same WWPN number on the same HBA card, and the old zone on SAN switch is till active. Please confirm if it could be the cause, or any other courses you can think of?
One way to resolve it is to remove WWPN from old zoning configuration on the switch. My question is, is there anything I can do on the host, to comopletely deconfigure these old LUNs?
Thank you for sharing!
