iscsi操作总结

增加iscsi存储

(1)发现iscsi存储:iscsiadm -m discovery -t st -p ISCSI_IP

(2)查看iscsi发现记录:iscsiadm -m node

(3)登录iscsi存储:iscsiadm -m node -T LUN_NAME -p ISCSI_IP -l

(4)开机自动: iscsiadm -m node –T LUN_NAME -p ISCSI_IP –op update -n node.startup -v automatic

删除iscsi存储

(1)登出iscsi存储 iscsiadm -m node -T LUN_NAME -p ISCSI_IP -u

(2)对出iscsi所有登录 iscsiadm -m node –logoutall=all

(3)删除iscsi发现记录:iscsiadm -m node -o delete -T LUN_NAME -p ISCSI_IP

登入需验证码的节点

(1)开启认证

iscsiadm -m node -T LUN_NAME -o update –name node.session.auth.authmethod –value=CHAP

*.使用-o同–op

(2)添加用户

iscsiadm -m node -T LUN_NAME –op update –name node.session.auth.username –value=[用户名]

(3)添加密码

iscsiadm –m node –T LUN_NAME –op update –name node.session.auth.password –value=[密码]
