Hello, currently I have a cluster of 3 hosts where each one has FC SAN connectivity to 4 LUNs: 3 are already configured as storage domains (1TB, 2TB, 4TB), one is free, not allocated. See here for screenshot: https://drive.google.com/file/d/0BwoPbcrMv8mvRVZZMTlNcTQ5MGs/view?usp=sharing
At the moment the command "multipath -l" run on hosts shows all the 4 LUNs. Now I want to do 2 things at storage array level: - remove the 2TB storage domain LUN - remove the 20Gb LUN not yet allocated What is the correct workflow, supposing I have already emptied the 2TB from VM disks ad such? Select 2Tb SD, then Datacenter subtab, then "maintenance", detach" and at the end "remove"? I think I continue to see 4 LUNs at this point, correct? Now I proceed with removal of lun at storage array level? Should I select an SD line and then "Scan disks" to see refresh the SAN and see in multipath only 2 of them at the end? Or any manual command at host level before removal from array? Thanks in advance Gianluca
