I was installing Clusterware using ASM on VMware shared disks. When I created the independent persistent virtual disks, I left the “allocate all disk space now” option unselected. Oracleasm was happy on both RAC nodes. The Oracle installer was happy when it created +ASM1 on the first RAC node. But when the ASM instance started on node 2 it did not like the “virtually provisioned” disk. The +ASM2 instance was not open and was complaining about one of the shared disks being corrupt at a certain byte. When I checked the virtual disk files, I saw that Oracle was trying to read past the end of the file. I started all over with new fully allocated shared disk and that fixed the problem. Everything is up and running now.
该方法我尝试后依旧未能解决，最终，通过修改vmx文件，添加如下：
在每一个scsi1:x的下面添加scsi1:x.deviceType = "plainDisk"
scsi1:1.present = "TRUE"
scsi1:1.mode = "independent-persistent"
scsi1:1.filename = "K:\VMDisk\Sharedisk\ocr.vmdk"
scsi1:1.deviceType = "plainDisk"
scsi1:2.present = "TRUE"
scsi1:2.mode = "independent-persistent"
scsi1:2.filename = "K:\VMDisk\Sharedisk\votingdisk.vmdk"
scsi1:2.deviceType = "plainDisk"
scsi1:3.present = "TRUE"
scsi1:3.mode = "independent-persistent"
scsi1:3.filename = "K:\VMDisk\Sharedisk\data.vmdk"
scsi1:3.deviceType = "plainDisk"
scsi1:4.present = "TRUE"
scsi1:4.mode = "independent-persistent"
scsi1:4.filename = "K:\VMDisk\Sharedisk\backup.vmdk"
scsi1:4.deviceType = "plainDisk"
scsi1:5.present = "TRUE"
scsi1:5.mode = "independent-persistent"
scsi1:5.filename = "K:\VMDisk\Sharedisk\ocr2.vmdk"
scsi1:5.deviceType = "plainDisk"
并添加：
disk.locking = "false"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.DataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
disk.EnableUUID = "TRUE"
终于第二节点跑过了root.sh
