4 执行iscsi sendtarget 发现

#  iscsiadm -m discovery -t sendtargets -p 192.168.1.124:3260192.168.1.124:3260,1 iqn.2004-04.com.qnap:ts-809:iscsi.vnat001.c50c55

 下面为新发现的target

 

5 登陆target

＃　iscsiadm -m node -T iqn.2004-04.com.qnap:ts-809:iscsi.vnat001.c50c55 -p 192.168.1.124:3260 -l

 

6 查看iSCSI session信息

 

[root@localhost ~]# iscsiadm -m session -i
