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]
