oracle 11g rac安装之grid报错解决

haloi

　　1.在rac2节点使用oracleasm找不到共享磁盘
　　[root@rac2 ~]# oracleasm scandisks
　　Reloading disk partitions: done
　　Cleaning any stale ASM disks...
　　Scanning system for ASM disks...
　　[root@rac2 ~]#
　　解决方法:
　　是因为在rac1节点格式化磁盘没有使用partprobe命令,分区没有生效
　　在rac1执行:
　　[root@rac1 ~]# partprobe
　　在rac2执行:
　　[root@rac2 ~]# /usr/sbin/oracleasm scandisks
　　Reloading disk partitions: done
　　Cleaning any stale ASM disks...
　　Scanning system for ASM disks...
　　Instantiating disk "VOL04"
　　Instantiating disk "VOL03"
　　Instantiating disk "VOL01"
　　Instantiating disk "VOL02"
　　[root@rac2 ~]# /usr/sbin/oracleasm listdisks
　　VOL01
　　VOL02
　　VOL03
　　VOL04
　　[root@rac2 ~]#
　　2.安装grid集群软件时出现ORACLE_HOME和ORACLE_BASE目录不对
　　错误提示:
　　INS-32026]The Software Location specified should not be under Oracle base location.
　　CAUSE: Grid Infrastructure for a Cluster installation will assign root ownership to all parent directories of clusterware software location. As a result, all named directories in the software location path will acquire root ownership. This may create problems for subsequent installations into the same Oracle base.
　　ACTION: Specify software location outside of Oracle base
　　解决方法:
　　我当前目录是:ORACLE_BASE=/home/grid
　　ORACLE_HOME=/home/grid/11.2.0/grid
　　这样目录是不正确的,因为ORACLE_BASE和ORACLE_HOME目录要分开,ORACLE_BASE安装好后是有root权限的,而ORACLE_HOME则没有.
　　这样才对:ORACLE_BASE=/home/grid/app
　　ORACLE_HOME=/home/grid/11.2.0/grid
　　3.在安装grid到最后一步出错误,是因为scan的IP问题补占用了

　　日志:
　　INFO: All nodes have same "hosts" entry defined in file "/etc/nsswitch.conf"
　　INFO: Check for integrity of name service switch configuration file "/etc/nsswitch.conf" passed
　　INFO: ERROR:
　　INFO: PRVG-1101 : SCAN name "scan-cluster" failed to resolve
　　INFO: ERROR:
　　INFO: PRVF-4657 : Name resolution setup check for "scan-cluster" (IP address: 192.168.3.155) failed
　　INFO: ERROR:

　　INFO: Checking OLR integrity...

　　INFO: OLR file check successful
　　解决方法:
　　(1).直接跳过不影响
　　(2),修改系统的nslookup二进制文件(http://www.ithao123.cn/content-1094742.html)
　　4.crs无法共享磁盘通信
　　错误信息:
　　CRS-0184: Cannot communicate with the CRS daemon.

　　解决方法:
　　这是共享磁盘的问题,我是用iscsi做的共享,查看了下asm只能挂载自己在磁盘组,将共享磁盘换成虚拟机自带的磁盘共享就解决了.
