iSCSI lun assignments change after "service iscsi restart" and become read-only

Solution Verified - Updated -

Issue

  • How can I make the system recognize newly cloned iSCSI LUNs?
  • How can I rescan for new iSCSI LUNs without changing the LUN assignments?
  • I've tried to rescan the system with "service iscsi restart", but this causes already mounted filesystems to lose their assigned device which are already mounted.
