由于我安装了Redhat Linux AS4版本的系统，目前的开源版本还不支持。 查询了一下Redhat的发行记录,在Redhat Linux AS4 初始版本中不包括iscsi部分:
红帽企业 Linux 4 的初始发行版本不包括对 iSCSI 软件 initiator 或 target 的支持。对 iSCSI 的支持正处于测试阶段，测试的结果将决定对 iSCSI 的支持是否会被包括在以后的 红帽企业 Linux 4 升级产品中。
然后在Redhat Linux AS4 Update2中包含了关于iSCSI的支持，通过初始安装或手工安装以下组件可以加载iscsi组件: iscsi-initiator-utils-4.0.3.0-2
在Redhat Linux AS4 Update2上安装很简单，内核版本为2.6.9-22:

在Redhat Linux AS4 初始发行版本（内核版本为2.6.9-11）上安装，会遇到点问题，需要sysfsutils-1.2.0-1.i386.rpm的支持，这个rpm包可以从网上下载,搜索rpm包rpm.pbone.net是个很好的站点。 1.在内核2.6.9-11上安装的提示
[root@test1 opt]# uname -a Linux test1.hurray.com.cn 2.6.9-11.ELsmp #1 SMP Fri May 20 18:26:27 EDT 2005 i686 i686 i386 GNU/Linux

2.下载安装sysfsutils

3.安装iscsi-initiator-utils-4.0.3.0-2
