add new disk in /etc/tgt/targets.conf and reload without affect other disks/initiator hosts

I have added a new disk to the server: [root@ns1 tgt]# lsblk |grep sdh sdh 8:112 0 600M 0 disk Also, I have created a new entry for /dev/sdh in /etc/tgt/targets.conf [root@ns1 tgt]# cat /etc/tgt/targets.conf |grep /dev/ direct-store /dev/sdb direct-store /dev/sdc direct-store /dev/sdd direct-store /dev/sde direct-store /dev/sdf direct-store /dev/sdg direct-store /dev/sdh [root@ns1 tgt]# How can I reload the new configuration and make available the new lun? I have tried systemctl reload tgtd, tgt-admin -e and tgt-admin --ready ALL, but none has worked. Bellow we can see there is no /dev/sdh yet. [root@ns1 tgt]# tgtadm --mode target --op show|grep /dev/ Backing store path: /dev/sdb Backing store path: /dev/sdc Backing store path: /dev/sdd Backing store path: /dev/sde Backing store path: /dev/sdf Backing store path: /dev/sdg [root@ns1 tgt]# I have tested with systemctl restart tgtd and it has worked, but it affect the initiator hosts. ie after restart tgtd (log from some initiator host): Jun 6 18:20:41 rac1 kernel: connection1:0: detected conn error (1020) Jun 6 18:20:41 rac1 iscsid: iscsid: Kernel reported iSCSI connection 1:0 error (1020 - ISCSI_ERR_TCP_CONN_CLOSE: TCP connection closed) state (3) Jun 6 18:20:43 rac1 iscsid: iscsid: Kernel reported iSCSI connection 1:0 error (1020 - ISCSI_ERR_TCP_CONN_CLOSE: TCP connection closed) state (2) Jun 6 18:20:43 rac1 kernel: connection1:0: detected conn error (1020) Jun 6 18:20:45 rac1 kernel: connection1:0: detected conn error (1020) Jun 6 18:20:45 rac1 iscsid: iscsid: Kernel reported iSCSI connection 1:0 error (1020 - ISCSI_ERR_TCP_CONN_CLOSE: TCP connection closed) state (2) Jun 6 18:20:46 rac1 kernel: session1: session recovery timed out after 5 secs Jun 6 18:20:47 rac1 multipathd: checker failed path 8:112 in map data1 Jun 6 18:20:47 rac1 multipathd: data1: remaining active paths: 0 Jun 6 18:20:47 rac1 kernel: device-mapper: multipath: Failing path 8:112.
