VMware Workstation 8 RAC 共享磁盘配置

vmware server配置已经不存在问题了，

winddows 7对vmware server1.0.8的支持不太好，决定采用VMware Workstation 8试试，官方说支持share disk了下面是配置方式

首先在任意一节点增加四块磁盘分别：两个1GB（OCR），一个6GB（数据盘），一个5GB（日志盘）

添加磁盘的时候选择：

Independent-Persistent

Allocate all disk space now – store virtual disk as a single file

添加完以后记得更改下所有磁盘的SCSI总线，选中磁盘，然后点击右边的Advanced

 弹出的Virtual device node中选择1:0

 其他几个共享盘依次操作，分别是1:1,1:2,1:3

配置磁盘共享参数

 

找到两个节点的RHEL5 11GR2 RAC1.vmx ，RHEL5 11GR2 RAC1.vmx 文件

 

将其中文件末尾的scsi1相关的内容改为如下格式

 

scsi1.present = “TRUE”

scsi1.virtualDev = “lsilogic”

scsi1.sharedBus = “virtual”

scsi1:0.present = “TRUE”

scsi1:0.fileName = “E:\VMware\RAC\share\OCR1.vmdk”

scsi1:0.mode = “independent-persistent”

scsi1:0.deviceType = “disk”

scsi1:1.present = “TRUE”

scsi1:1.fileName = “E:\VMware\RAC\share\OCR2.vmdk”

scsi1:1.mode = “independent-persistent”

scsi1:1.deviceType = “disk”

scsi1:2.present = “TRUE”

scsi1:2.fileName = “E:\VMware\RAC\share\DATA.vmdk”

scsi1:2.mode = “independent-persistent”

scsi1:2.deviceType = “disk”

scsi1:3.present = “TRUE”

scsi1:3.fileName = “E:\VMware\RAC\share\BACK.vmdk”

scsi1:3.mode = “independent-persistent”

scsi1:3.deviceType = “disk”

disk.locking = “FALSE”

diskLib.dataCacheMaxSize = “0″

diskLib.dataCacheMaxReadAheadSize = “0″

diskLib.dataCacheMinReadAheadSize = “0″

diskLib.dataCachePageSize = “4096″

diskLib.maxUnsyncedWrites = “0″

修改完成后启动两个节点，在两个节点分别执行fdisk -l是都可以刚增加的四块硬盘的

安装rac的时候会遇到一个错误，bug，忽略即可，生产环境且不可忽略。
