Linux挂载ISCSI TARGET磁盘
1.安装iscsi-initiator-utils包：
[root@rhel2 .vnc]#mount /dev/cdrom /mnt
mount: block device /dev/cdrom is write-protected, mounting read-only
[root@rhel2 .vnc]# cd /mnt/Server
[root@rhel2 Server]#rpm -ivh iscsi-initiator-utils-6.2.0.871-0.10.el5.i386.rpm
warning: iscsi-initiator-utils-6.2.0.871-0.10.el5.i386.rpm: Header V3 DSA signat
ure: NOKEY, key ID 37017186

2.确保和存储服务器的连通：
[root@rhel2 Server]#ping 1.1.1.1
PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.
64 bytes from 1.1.1.1: icmp_seq=1 ttl=64 time=7.12 ms
--- 1.1.1.1 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 7.129/7.129/7.129/0.000 ms
3.探测存储设备失败：
[root@rhel2 Server]#iscsiadm -m discovery -t sendtargets -p 1.1.1.1:3260
iscsiadm: can not connect to target="_self">iSCSI daemon (111)!
iscsiadm: can not connect to iSCSI daemon (111)!
iscsiadm: Cannot perform. discovery. Initiatorname required.
iscsiadm: Discovery process to 1.1.1.1:3260 failed to create a discovery session.
4.安装kernel相关包：
需要安装iscsi-target，这个可以到sf.net上下载最新的来编译，编译需要内核文件，所以要安装kernel,kernel-devel,kernel-headers3个包。
安装这3个包：
[root@rhel2 Server]# ls kernel*
kernel-2.6.18-164.el5.i686.rpm kernel-headers-2.6.18-164.el5.i386.rpm
kernel-debug-2.6.18-164.el5.i686.rpm kernel-PAE-2.6.18-164.el5.i686.rpm

kernel-doc-2.6.18-164.el5.noarch.rpm kernel-xen-devel-2.6.18-164.el5.i686.rpm
[root@rhel2 Server]#rpm -ivh kernel-devel-2.6.18-164.el5.i686.rpm kernel-headers-2.6.18-164.el5.i386.rpm

5.安装iscsi-target：
[root@rhel2 Server]# cd /opt/soft/
[root@rhel2 soft]# ls

11.再次探测存储，成功：
[root@rhel2 init.d]#iscsiadm -m discovery -t sendtargets -p 1.1.1.1:3260

12.将探测到的存储挂载到本地：
[root@rhel2 init.d]#iscsiadm -m node -T iqn.2006-01.com.openfiler:tsn.af7b14fe4761 -p 1.1.1.1:3260 -l
