Redhat Linux从AS3 update 4开始集成iscsi-initiator。
[root@dell2650 etc]# cat /etc/redhat-release
Red Hat Enterprise Linux AS release 3 (Taroon Update 4)
[root@dell2650 etc]# rpm -qa|grep iscsi
iscsi-initiator-utils-3.6.2-4
|
在NETAPP上可以通过如下步骤分配iSCSI LUN
在菜单Luns部分，选择Add:
设置好相应的参数增加即可。
如果一切正常，即可显示成功:
添加成功后可以在如下界面查看:
此时可以在管理主机上启动/重新启动iscsi进程以识别增加的设备:
[root@dell2650 dev]# /etc/init.d/iscsi stop
Stopping iSCSI: iscsid[ OK ]
[root@dell2650 dev]# /etc/init.d/iscsi start
Starting iSCSI: iscsi iscsid[ OK ]

我们可以通过dmesg获得硬件信息:

从这里可以看到其设备符为:sdb,我们此时就可以向操作普通硬盘一样操作iSCISI硬盘了.
以下是简单的分区过程:
