vmware server2 RAC的共享盘设置问题

1. 把第二块盘设置成scsi1控制，设置硬盘为independent-persistent,在两个节点都做同样的添加。

2. 添加或修改如下参数：

scsi1:0.mode = "independent-persistent"
scsi1.present = "TRUE"
#scsi1.sharedBus = "none"
scsi1.virtualDev = "lsilogic"
scsi1:0.present = "TRUE"
scsi1:0.fileName = "D:\VM RAC\vm_rac1\vm_shared_disk.vmdk"
scsi1:0.writeThrough = "TRUE"


disk.locking = "FALSE"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.DataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
scsi1.sharedBus = "virtual"
scsi1.shared = "TRUE"

3. 然后，启动两个vm，在第一个节点上，做fdisk共享盘，然后，partprobe 这个设备，在节点一查看下，再节点2再查看下，看看是否同步：

。。。。。
