1.查看target 信息
# tgt-admin --show
或者
# tgtadm --lld iscsi --mode target --op show

2.手动发现target，侦测 172.26.80.5 这部 iSCSI 设备的相关数据
#iscsiadm -m discovery -t sendtargets -p 172.26.80.5
3.显示系统所有target
#iscsiadm -m node
172.26.80.5:3260,1 iqn.2010-10.org.openstack:volume-00000008
4.登入target
# iscsiadm -m node -T iqn.2010-10.org.openstack:volume-00000008 --login
Logging in to [iface: default, target: iqn.2010-10.org.openstack:volume-00000008, portal: 172.26.80.5,3260]
Login to [iface: default, target: iqn.2010-10.org.openstack:volume-00000008, portal: 172.26.80.5,3260]: successful
#fdisk -l 可以查看到多了一个新的磁盘，大小和volume-00000008一样大
5.登出target
# iscsiadm -m node -T iqn.2010-10.org.openstack:volume-00000008 --logout
Logging out of session [sid: 1, target: iqn.2010-10.org.openstack:volume-00000008, portal: 172.26.80.5,3260]
Logout of [sid: 1, target: iqn.2010-10.org.openstack:volume-00000008, portal: 172.26.80.5,3260]: successful
6.查看建立的session
#iscsiadm -m session
tcp: [3] 172.26.80.5:3260,1 iqn.2010-10.org.openstack:volume-00000008
只有登录target才能看到会话
7.删除target
#iscsiadm -m node -o delete -T iqn.2010-10.org.openstack:volume-00000008
只有logout后，才能删除target
