AIX 中以并发模式挂载VG

来源：互联网发布：中国导弹水平知乎编辑：程序博客网时间：2024/04/30 19:31

要想以并发模式挂载VG 必须要有/usr/sbin/gsclvmd 这个进程，而些进程是安装HACMP 的必要的文件集bos.clvm.enh，同时gsclvmd 也是由HACMP 启动的，多个节点挂载并发VG 的时候是以并发模式挂载的，当然我们在有gsclvmd 服务的时候也可以手工以手工方式挂载，如下所示：

# ps -ef | grep gsc
root 6553738 14680086 0 18:13:58 pts/0 0:00 grep gsc
root 16973844 4784366 0 17:45:02 - 0:00 /usr/sbin/gsclvmd
