本章主要是搜集了一些安装rac的过程中出现的问题及解决办法，如果没有出现问题的话那么这一章可以不看的
目录结构：
新安装了Oracle 11g rac之后，不知道是什么原因导致第二个节点上的crsd无法启动？其错误消息是CRS-4535: Cannot communicate with Cluster Ready Services。其具体的错误信息还需要查看crsd.log日志才知道。
1、环境
[root@linux2 ~]# cat /etc/issue

[root@linux2 bin]# ./crsctl query crs activeversion

#注意下文中描述中使用了grid与root用户操作不同的对象。
2、错误症状

CRS-4124: Oracle High Availability Services startup failed.

ohasd failed to start: Inappropriate ioctl for device

第一次安装11gR2 RAC的时候就遇到了这个11.0.2.1的经典问题，上网一查才知道这是个bug，解决办法也很简单，
就是在执行root.sh之前执行以下命令
/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1
如果出现
/bin/dd: opening`/var/tmp/.oracle/npohasd': No such file or directory
的时候文件还没生成就继续执行，直到能执行为止，一般出现Adding daemon to inittab这条信息的时候执行dd命令。
另外还有一种解决方法就是更改文件权限
chown root:oinstall /var/tmp/.oracle/npohasd
重新执行root.sh之前别忘了删除配置：/u01/app/11.2.0/grid/crs/install/roothas.pl -deconfig -force-verbose
其中一个必要条件是网卡要一致，一致性表现在这几个方面
1.网卡名要一模一样，比如都叫eth0, eth2，不能出现一台节点eth0,eth2,另一台eth3, eth4
我在安装的时候就出现这种错误，造成的现象就是第一台节点能正常安装，但是第二台执行root.sh的时候总是报错Failed to Start CSSD。
2.不仅名字要一样，而且对应的public, private也要一致，也就是说不能一台
eth0: 192.168.1.2
eth2: 10.10.1.2
另一台
eth0: 10.10.1.3
eth2: 192.168.1.3
3.不仅地址要对应，还要求子网掩码要一致，也就是同一个public,private网络不能一台子网掩码
255.255.0.0
另一台的子网掩码是255.255.255.0
采用虚拟机克隆的话，网卡名不一致是最常见的。
Redhat Enterprise Linux 6下网卡名的修改方法：(比如eth6需要改成eth0)
1.修改配置文件 /etc/udev/rules.d/70-persistent-net.rules，把其中的网卡名改成新的网卡名
2.配置文件/etc/sysconfig/network-script/ifcfg-eth6也需要改成ifcfg-eth0
3./etc/rc.d/init.d/network restart重新启动
Oracle RAC的安装真是麻烦。一旦设置不对，后面就会出现各种错误。
补充：建议用同型号的网卡，不一样行不行没有试过但是根据资料，至少网卡的MTU（最大传输单元）必须要一致，否则也会导致错误。
现象：
在Redhat Linux 6上安装Oracle RAC的过程中，到65%的时候就没有任何反应。
原因：
因为防火墙开着
解决方法
chkconfig iptables off
service iptables stop

这里我们就给出配置UDEV的具体步骤，还是比较简单的:
1.确认在所有RAC节点上已经安装了必要的UDEV包
[root@rh3 ~]# rpm -qa|grep udev udev-095-14.21.el5
2.通过scsi_id获取设备的块设备的唯一标识名，假设系统上已有LUN sdc-sdp
fori inc d e f g h i j k l m n o p ;
do
echo"sd$i""`scsi_id -g -u -s /block/sd$i` ";
done
sdc 1IET_00010001
sdd 1IET_00010002
sde 1IET_00010003
sdf 1IET_00010004
sdg 1IET_00010005
sdh 1IET_00010006
sdi 1IET_00010007
sdj 1IET_00010008
sdk 1IET_00010009
sdl 1IET_0001000a
sdm 1IET_0001000b
sdn 1IET_0001000c
sdo 1IET_0001000d
sdp 1IET_0001000e
以上列出于块设备名对应的唯一标识名
3.创建必要的UDEV配置文件，
首先切换到配置文件目录
[root@rh3 ~]# cd /etc/udev/rules.d
定义必要的规则配置文件
[root@rh3 rules.d]# touch 99-oracle-asmdevices.rules
[root@rh3 rules.d]# cat 99-oracle-asmdevices.rules

Result为/sbin/scsi_id -g -u -s %p的输出--Match the returned string of the last PROGRAM call. This key may be used inany following rule after a PROGRAM call.
按顺序填入刚才获取的唯一标识名即可
OWNER为安装Grid Infrastructure的用户，在11gr2中一般为grid，GROUP为asmadmin，MODE采用0660即可
NAME为UDEV映射后的设备名，
建议为OCR和VOTE DISK创建独立的DISKGROUP，为了容易区分将该DISKGROUP专用的设备命名为ocr1..ocrn的形式
其余磁盘可以根据其实际用途或磁盘组名来命名
4.将该规则文件拷贝到其他节点上
[root@rh3 rules.d]# scp 99-oracle-asmdevices.rules Other_node:/etc/udev/rules.d
5.在所有节点上启动udev服务，或者重启服务器即可
[root@rh3 rules.d]# /sbin/udevcontrol reload_rules
[root@rh3 rules.d]# /sbin/start_udev Starting udev: [ OK ]
6.检查设备是否到位
[root@rh3 rules.d]# cd /dev [root@rh3 dev]# ls -l ocr* brw-rw---- 1 grid asmadmin 8, 32 Jul 10 17:31 ocr1 brw-rw---- 1 grid asmadmin 8, 48 Jul 10 17:31 ocr2

自"手把手教你用VMware在linux下安装oracle10g RAC"一文发布以来，俺个人的虚荣心再一次得到了极大满足，因为持续不断的有朋友对俺持续不断地表达感谢(就是没几个表示请俺吃饭的，5555，这帮口惠心不实的家伙`~~)，说俺这篇文档写的好是写的妙，不光步骤清晰又明了，还有图片做参照。
不过，这其中也有不少朋友与我联系，说是安装过程中遇到问题，其中大多数 问题 均是 出在 节点2执行oracleasm listdisks时检测不到共享的磁盘。
对于vmware下配置RAC数据库，出现这一问题的原因通常有两个方面，下面分别描述 。
１、VMWARE中添加磁盘共享参数
使用VMWARE 配置RAC数据库，一定要选择server的VMWARE(VMWARE分为server和workstation两种类型)，这一点三思在文档中专门强调了，有些朋友可能仍未注意 ；再一个就是 各个 vmware 节点的*.vmx配置文件中，添加相关的磁盘共享参数， 否则也有可能导致 无法正常识别共享的磁盘。
下面举一下三思配置环境时，vmx文件中关于磁盘共享参数的示例，如下：
disk.locking = "false"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.DataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
scsi1.sharedBus = "virtual"
２、共享磁盘不共享
第2个原因就更加BT了，不过这种问题导致磁盘无法共享的例子也不鲜见，出现这种问题 主要是对于 Oracle RAC 架构的理解不深入导致的。
在阐述主题之前，俺首先想明确一个相关概念：究竟何为共享存储。所谓 共享存储，顾名思义，也就是 磁盘空间应由相关的节点共享访问，更直白的讲就是节点访问的是同一个(或几个)磁盘， 对于虚机 环境 的话，就是访问相同的磁盘文件。
ORACLE 数据库是由实例+数据库组成，实例是由一组操作系统进程+操作系统的一块内存区域组成；数据库则是一堆各种类型的特性文件的合集(比如数据文件、临时文件，重做日志文件、控制文件等)，RAC环境的ORACLE数据库，实际上是多个实例(每个实例分别运行在不同的节点上----一般情况下，你要让它运行于同一个节点应该也是可行的)访问和读写一份数据库。数据库是放在哪呢，就是放在共享存储上，也就是说RAC的几个实例 访问的文件应该在 相 同的磁盘上 。
Ok，回到主题，有些朋友在创建第二个节点，为该节点添加用于voting disk,ocr以asm用的磁盘时，并不是选择第一个节点中创建的文件 (Use an existing virtual disk) ，而是又重新创建了 新的磁盘文件(Create a new virtual disk)， 这种情况完全没有共享的概念，自然也就不可能实现磁盘的共享存储了。
在安装GI，第一个节点的root.sh一般不易出错，但是第二个节点就遇到了下面的错误Start of resource"ora.asm -init"failedFailed to start ASMFailed to start Oracle Clusterware stack
