iscsiadm是open-iscsi包中的一个工具，用来发现和登陆iSCSI target。

关于iSCSI基本介绍，可以参考《鸟哥私房菜》，本文主要记录iscsiadm的常用命令，同时对其功能有大致的体会

发现

$ sudo iscsiadm -m discovery -t sendtargets -p 127.0.0.1:3260
127.0.0.1:3260,1 iqn.2010-10.org.openstack:volume-63cb9eb0-7eee-470e-b4a9-5c3d562926be
127.0.0.1:3260,1 iqn.2010-10.org.openstack:volume-252b5988-8f76-4988-a10b-413fb63d1a67

查看已发现的节点

$ sudo iscsiadm -m node
127.0.0.1:3260,1 iqn.2010-10.org.openstack:volume-63a98496-4f2a-4c37-bbb5-f4e5e6b304fe
127.0.0.1:3260,1 iqn.2010-10.org.openstack:volume-252b5988-8f76-4988-a10b-413fb63d1a67

查看会话状况

sudo iscsiadm -m session -P 3

登陆/登出

设置验证方式，用户名，密码

$ sudo iscsiadm -m node -T $iqn  --op update -n node.session.auth.authmethod -v CHAP -p <span style="font-family: Arial, Helvetica, sans-serif;">127.0.0.1:3260</span>
$ sudo iscsiadm -m node -T $iqn  --op update -n node.session.auth.username -v CHAP -p $portal
$ sudo iscsiadm -m node -T $iqn  --op update -n node.session.auth.password -v CHAP -p $portal

登陆，成功后会将target挂载到本地，可以通过上面的（session）查看详细信息

$ sudo iscsiadm -m node --targetname iqn.2010-10.org.openstack:volume-63cb9eb0-7eee-470e-b4a9-5c3d562926be -p 127.0.0.1:3260 --login

登出，卸载target

$ sudo iscsiadm -m node --target iqn.2010-10.org.openstack:volume-63a98496-4f2a-4c37-bbb5-f4e5e6b304fe -p 127.0.0.1:3260 --logout

Logout of [sid: 4, target: iqn.2010-10.org.openstack:volume-63a98496-4f2a-4c37-bbb5-f4e5e6b304fe, portal: 127.0.0.1,3260] successful.
