ISCSI 共享存储在RHEL5上的实现方法

1、iscsi 共享存储在rhel5上的实现方法近日辉总收拾了在vmware环境下安装rac的文档，没有涉及分享存储这层概念，有点美中不足，于是我向前推动一层，用法iscsi模拟分享存储的盘阵，讨论了一翻，收拾笔记内容如下，相关脚原来自唐sir，我狗尾续貂了一把，哈哈 环境介绍：服务器端：rhel5.4 64位, ip地址：客户端1: rehl6.0 64位，ip地址：客户端2: rehl5.4 64位，ip地址：95 一：服务器端：首先需要安装scsi-target-uti工具包，然后将tgtd服务设置成开机自动启动，然后划

2、出一个100g的lvm做分享盘阵，lvm的名称为datarootrhel5 yum -y install scsi-target-utils.x86_64 rootrhel5 service tgtd startstarting scsi target daemon: starting target framework daemonrootrhel5 tgtd on rootrhel5 lvs lv vg at lsize origin snap% move log copy% convert data volgroup00 -wi-ao 100.00g lv_data volgroup00

3、-wi-ao 50.00g lv_root volgroup00 -wi-ao 29.28g oracle10g_1 volgroup00 -wi-ao 100.00g 每次重启tgtd服务的时候，之前用法tgtdadmin绑定的target和logicalunit都会失效，因而写了个脚本用于简化操作iqn命名规范：iqn. :optional name，例如：iqn.2011-06-.766.rac:shardisk这里设置允许全部的ip举行举行挂载，取消target绑定的时候需要先取消logicalunit然后取消target rootrhel5 /e
