How to prevent an iSCSI LUN being accessed by multiple hosts?
QSAN provide the LUN masking function which can add specific host to access the LUN. The default value is “*” which means allow every host for accessing; you would need to enter the IQN name of the iSCSI initiator in this allowed Hosts column if you would like to prevent multiple hosts accessing issue.
