RAC环境中HACMP的vg为non-conrrent的解决经历

在rac环境中，HACMP的vg为unconcurrent状态，是多么糟糕的一件事，而这个不幸就在某生产系统上发生了。环境介绍：AIX6.1的系统，使用的是EMCCLARiiON存储，oracl

环境介绍：

AIX 6.1的系统，使用的是EMC CLARiiON存储，oracle10.2.0.5

问题状况：

   先看下各个卷组的状态

有好多盘不是missing就是removed的，数据库日志报错为：

两节点的gsclvmd 都是inoperative，看来只能重启hacmp来把gsclvmd给拉起来。

解决过程：

1.先进行数据库的备份，，然后停库：

节点1: su – oracle srvctl stop listener –n ctscrm1 ps –ef | grep “LOCAL=NO”| grep –v grep | awk ‘{print $2}’|xargs kill -9 oracle> alter system switch logfile; oracle> alter system checkpoint; srvctl stop instance –d ctsdb –I ctsdb1

节点2: su – oracle srvctl stop listener –n ctscrm2 ps –ef | grep “LOCAL=NO”| grep –v grep | awk ‘{print $2}’|xargs kill -9 oracle> alter system switch logfile; oracle>　alter system checkpoint; srvctl stop instance –d ctsdb –I ctsdb2

关闭crs：节点1和节点2

crsctlstop crs

2.重启hacmp
