1、安装客户端
[[email protected] Packages]# rpm -Uvh iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm warning: iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY Preparing... ########################################### [100%] 1:iscsi-initiator-utils ########################################### [100%] [[email protected] Packages]# rpm -q iscsi-initiator-utils iscsi-initiator-utils-6.2.0.873-2.el6.x86_64
2、设置服务自启动
[[email protected] Packages]# chkconfig --list | grep iscsi iscsi 0:off 1:off 2:off 3:on 4:on 5:on 6:off iscsid 0:off 1:off 2:off 3:on 4:on 5:on 6:off [[email protected] ~]# chkconfig iscsid on [[email protected] ~]# chkconfig iscsi on [[email protected] ~]# chkconfig --list | grep iscsi iscsi 0:off 1:off 2:on 3:on 4:on 5:on 6:off iscsid 0:off 1:off 2:on 3:on 4:on 5:on 6:off
【此处Linux的版本为RHEL 6.4，iSCSI的操作已于以往不同】
3、发现iSCSI Targets
[[email protected] ~]# iscsiadm -m discovery -t sendtargets -p 172.1.2.200:3260 [ OK ] iscsid: [ OK ] 172.1.2.200:3260,1 iqn.syksky.com.openfiler:tsn.7b99cc2f92ee
4、启动服务
[[email protected] ~]# service iscsi start Starting iscsi: [ OK ]
5、查看会话状态
【此处新版本，原先-i的参数已被替换，-P是print level，取值0-3，具体可以查看帮助】
[[email protected] ~]# iscsiadm -m session -P 3
