标题:11.2 RAC 系列-安装新主机,识别老存储-1-识别ASM磁盘

作者:Lunar©版权所有[文章允许转载,但必须以链接方式注明源地址,否则追究法律责任.]

在有些场景下,RAC环境中如果主机出现问题,比如硬件故障等,不能启动,我们需要尽快存储上的启动数据库,恢复业务,那么就需要迁移以前的RAC环境到新的主机环境下,我测试了11.2和12.1的RAC,恢复过程还是很快的,基本上就是安装软件的过程,如果真实场景恢复业务,有两种方法:
1,按照我这里的方法重新安装主机,恢复RAC和数据库
2,如果之前有可用的操作系统的备份(比如NBU备份了OS),那么直接使用NBU还原即可
.
我这里测试的是方法1,重新安装11204的GI(Grid Infrastructure)和ORACLE RDBMS软件,然后识别老存储。
测试环境:单节点RAC, 操作系统是OEL Linux 6.6, 数据库版本是11.2.0.4
11.2 RAC 系列-安装新主机,识别老存储-1-识别ASM磁盘
11.2 RAC 系列-安装新主机,识别老存储-2-准备识别数据库
11.2 RAC 系列-安装新主机,识别老存储-3-配置老存储的数据库
Oracle 12.1 RAC 系列-安装新主机,识别老存储和恢复数据库
.
首先,因为存储使用的是11204的ASM,测试过程只安装11204的GI(Grid Infrastructure)软件,不用OUI配置GI。

相应的checkpoint文件内容:

[root@lunar5 ~]# ll /u01/app/grid/Clusterware/ckptGridHA_lunar5.xml
-rw-r--r-- 1 grid oinstall 4176 Feb 15 19:31 /u01/app/grid/Clusterware/ckptGridHA_lunar5.xml
[root@lunar5 ~]#

   <CHECKPOINT LEVEL="MAJOR" NAME="ROOTCRS_NODECONFIG" DESC="ROOTCRS_NODECONFIG" STATE="SUCCESS"/>
</CHECKPOINTS>
[root@lunar5 ~]# 

这里看到“DESC=”ROOTCRS_NODECONFIG” STATE=”SUCCESS””表示GI已经配置完成。
图形界面点击ok,继续执行其余配置,配置完成后,再次检查checkpoint文件:

[root@lunar5 ~]# ll  /u01/app/grid/Clusterware/ckptGridHA_lunar5.xml
-rw-r--r-- 1 grid oinstall 4176 Feb 15 19:31 /u01/app/grid/Clusterware/ckptGridHA_lunar5.xml
[root@lunar5 ~]# cd /u01/app/grid/Clusterware/
[root@lunar5 Clusterware]# ll
total 8
-rw-r--r-- 1 grid oinstall 4176 Feb 15 19:31 ckptGridHA_lunar5.xml
[root@lunar5 Clusterware]# 

这里看到,checkpoint文件的日期没有变化,说明checkpoint文件是执行root.sh的时候才有用的,也就是这个过程是11.2中为了方便客户,增加了root.sh的失败后继续配置二设计的,非常体贴的功能。在12.2中,该功能更加方便,他将会只管的告诉你当前配置的检查点情况,如果有些步骤失败后,oracle会自动清除老的配置,以便可以失败安装后不用重装,而是纠正错误后继续配置,类似“断点续传”那种意思。
.
比如,下面是12.2beta上安装RAC时执行root.sh的过程:

[root@lunar1 ~]#  /stage/root.sh
Performing root user operation.

The following environment variables are set as:
    ORACLE_OWNER= grid
    ORACLE_HOME=  /stage

检查ASM磁盘组中的内容(比如包含哪些数据库),因为ASM是采用OMF的,因此大部分情况下,通过磁盘组的目录结构就可以看出来这个存储中以前包含哪些数据库和其他相关信息:

这里看到,该存储中,包含了一个数据库,crsdg中的信息已经被我删除了,因此,没有老的ocr和voting disk文件了

现在,已经确定只有datadg2上面有数据,因此可以重组磁盘组,以便合理利用空间(后续我要用这个vm做很多其他测试):

ASMCMD> lsdg

使用kfod查看:

确认当前的crs状态都是正常的:

[root@lunar5 ~]# crsctl status res -t

至此老存储的ASM磁盘组已经在新的主机上可以识别了。
