磁盘变化导致RAC不能启动

311ybb

虚拟机：virtual box 4.3.6
操作系统：Oracle Linux Server release 5.6
clusterware:10.2.0.1.0
数据库：10.2.0.1.0

现象： 在虚拟机上安装的RAC，原来使用的是固定大小的共享盘，系统内通过raw方式配置，现在raw设备结果如下
/etc/sysconfig/rawdevices文件：
/dev/raw/raw1   /dev/sdb1
/dev/raw/raw2   /dev/sdb2
/dev/raw/raw4   /dev/sdd

# fdisk -l /dev/sdb

Disk /dev/sdb: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sdb2              33          64      257040   83  Linux

# raw -qa

# ls -l  /dev/raw/*

crw-rw---- 1 oracle oinstall 162, 4 May 14 10:16 /dev/raw/raw4

# cat /etc/oracle/ocr.loc
ocrconfig_loc=/dev/raw/raw1

后来测试Linux 的multipath ，通过Openfiler，连接两个网卡模拟，创建了一个normal 的diskgroup 。
# multipath -ll

重启数据库主机后，CRS不能启动/var/log/messages内容：
May 14 10:33:51 db1 logger: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.2962.

# cat /tmp/crsctl.2931
OCR initialization failed accessing OCR device: PROC-26: Error while accessing the physical storage Operating System error [Device or resource busy] [16]


现在看OCR的磁盘raw和fdisk结果跟以前没什么区别，这个该从哪下手解决解决？
