1、在enterprise linux4上安装oracle clusterware 10.2.0.1.0 时，要求在各节点上执行root.sh时报的错误：

metalink上查询到doc id为 466673.1，按如下方法解决

检查clsfmt命令运行状况:

[root@rac01 bin]$ ./clsfmt ocr /dev/raw/raw1
clsfmt: Received unexpected error 4 from skgfifi
skgfifi: Additional information: -2
Additional information: 104857600

下载补丁284719，并用补丁中的clsfmt.bin替换$CRS_HOME/bin/clsfmt.bin文件

rac1@oracle[/tmp]> unzip *zip
Archive: p4679769_10201_LINUX.zip
creating: 4679769/
inflating: 4679769/clsfmt.bin
inflating: 4679769/README.txt
rac1@oracle[/tmp]> cd 4679769/
rac1@oracle[/tmp/4679769]> cp clsfmt.bin /oracle/product/crs/bin/

使用dd命令将ocr信息删除(如果补丁文件替换后，不dd清理ocr,执行root.sh报错还是一样，切记)

[root@rac01 bin]dd if=/dev/zero of=/dev/raw/raw1 bs=1024 count=256
dd: writing `/dev/raw/raw1': No space left on device
101+0 records in
100+0 records out
104857600 bytes (105 MB) copied, 1.98218 seconds, 52.9 MB/s

这时，再次执行root.sh，问题解决

2、ASM: rac2节点mount diskgroup报错

SQL> alter diskgroup DG1 mount;
alter diskgroup DG1 mount
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "DG1"

ERROR: no PST quorum in group 1: required 2, found 0
ERROR: diskgroup DG1 was not mounted

Metalink(309815.1): There are two issues with using multipath disks in ASM. ASM cannot handle seeing the same disk twice. If it does, it will cause an error.

vi /etc/sysconfig/oracleasm
ORACLEASM_SCANORDER=”oracleasm”
ORACLEASM_SCANEXCLUDE=”sdb sdc sdd sde sdf”
