1、安装客户端
[root@node01 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%] [root@node01 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
[root@node01 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 [root@node01 ~]# chkconfig iscsid on [root@node01 ~]# chkconfig iscsi on [root@node01 ~]# 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
[root@node01 ~]# 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
[root@node01 ~]# 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】
[root@node01 ~]# iscsiadm -m session -P
iSCSI Transport Class version 2.0-

6、发现的新磁盘
[root@node01 ~]# fdisk -l | grep "Disk /dev" Disk /dev/sda: 42.9 GB, bytes Disk /dev/mapper/vg_node01-lv_root: 38.2 GB, bytes Disk /dev/mapper/vg_node01-lv_swap: MB, bytes Disk /dev/sdb: MB, bytes Disk /dev/sdc: MB, bytes Disk /dev/sdf: MB, bytes Disk /dev/sde: MB, bytes Disk /dev/sdd: MB, bytes Disk /dev/sdg: MB, bytes Disk /dev/sdh: MB, bytes Disk /dev/sdj: MB, bytes Disk /dev/sdi: MB, bytes Disk /dev/sdl: MB, bytes Disk /dev/sdk: MB, bytes Disk /dev/sdn: MB, bytes Disk /dev/sdm: MB, bytes Disk /dev/sdo: MB, bytes Disk /dev/sdp: MB, bytes Disk /dev/sdq: MB, bytes
