你说的是配置asm盘吗？可以用udev方式来做

####添加scsi设置

vi  /etc/scsi_id.config

options=-g

####获得磁盘scsi_id

## Linux 6

/sbin/scsi_id -g -u -d /dev/sdb

##Linux 7

/usr/lib/udev/scsi_id -g -u -d /dev/sdb

####映射磁盘及规则

vi /etc/udev/rules.d/99-oracle-asmdevices.rules

##linux 6

KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="36000c295e277570b8390c69cc7d46188", NAME="asmdisks/ocrvotedisk01", OWNER="grid", GROUP="asmadmin", MODE="0660"

###测试

/sbin/start_udev

ls –l /dev/asm*

##linux 7

KERNEL=="sd?1", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="1ATA_VBOX_HARDDISK_VBaa5c0f02-73fc8889", SYMLINK+="asmdisks/datadisk01", OWNER="grid", GROUP="asmadmin", MODE="0660"

###测试

/sbin/udevadm trigger --type=devices --action=change

ls –l /dev/asm*

刷不出来用

partprobe刷新下磁盘

###用multipath多路径绑定的盘做udev

linux7

用fdisk划分原始盘就可以了

vi /etc/udev/rules.d/12-dm-permissions.rules

ENV{DM_NAME}=="mpatha1", OWNER:="grid", GROUP:="asmadmin", MODE:="660"

ENV{DM_NAME}=="mpatha2", OWNER:="grid", GROUP:="asmadmin", MODE:="660"

ENV{DM_NAME}=="mpatha3", OWNER:="grid", GROUP:="asmadmin", MODE:="660"

ENV{DM_NAME}=="mpatha4", OWNER:="grid", GROUP:="asmadmin", MODE:="660"

ENV{DM_NAME}=="mpatha5", OWNER:="grid", GROUP:="asmadmin", MODE:="660"

ENV{DM_NAME}=="mpatha6", OWNER:="grid", GROUP:="asmadmin", MODE:="660"

###清空记录

multipath –F

###重新扫盘

multipath –v2

###检查共享盘

ll /dev/mapper/*

###检查权限

ls –l /dev/dm* |grep grid

自己windows电脑安装虚拟机软件，怎样把两个虚拟机的磁盘做成共享的磁盘

能给一个虚拟机下安装rac的安装步骤吗

OracleBase上有很多：
