One database was down today. So I login the server try to check and fix it. I found the Oracle home do not exist. So I check the /etc/fstab and found below.
[root@aaaa~]# cat /etc/fstab # This file is edited by fstab-sync - see 'man fstab-sync' for details LABEL=/ / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 none /dev/pts devpts gid=5,mode=620 0 0 none /dev/shm tmpfs defaults 0 0 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 LABEL=SW-cciss/c0d0p3 swap swap defaults 0 0 /dev/vx/dsk/orabin1adg/orabin /opt/oracle/product/10.2 vxfs defaults 1 2
The file system /dev/vx/dsk/orabin1adg/orabin is the directory should be mounted but not. It is controlled by VCS so I try to mount it with VCS.
First I use hastatus to check. Hit below
[root@aaaa~]# hastatus attempting to connect.... VCS ERROR V-16-1-10600 Cannot connect to VCS engine attempting to connect....not available; will retry attempting to connect....retrying VCS ERROR V-16-1-10600 Cannot connect to VCS engine attempting to connect....not available; will retry attempting to connect....retrying VCS ERROR V-16-1-10600 Cannot connect to VCS engine attempting to connect....not available; will retry
Then I start the VCS
[root@pss1sitdb1a ~]# /etc/init.d/vcs start
Starting vcs: [ OK ]
Then I use hastatus to check
[root@pss1sitdb1a ~]# hastatus attempting to connect.... attempting to connect....connected group resource system message --------------- -------------------- -------------------- -------------------- aaaa RUNNING MultiNIC_sg aaaa ONLINE cvm aaaa STARTING OFFLINE nfs_sg aaaa OFFLINE -------------------------------------------------------------------------
Try to online the nfs_sg hit below
[root@aaaaa~]# hagrp -online nfs_sg -sys aaaa VCS WARNING V-16-1-10154 Group nfs_sg is frozen
Then
[root@aaaaa~]# hagrp -unfreeze nfs_sg -persistent VCS WARNING V-16-1-11309 Configuration must be ReadWrite
Here is a quota which can explain the frozen.
Freezing a Service Group 凝固一个服务组是为了防止它离线；上线；或者failover. 当你凝固一个服务组时，VCS继续监视这个资源，但是不允许服务组(或者它的资源)背离线或者上线，failover也被禁止，即使资源故障。 注意：当凝固的时，VCS不能在服务组上面采取行动即使你通过带起服务上线在另一个系统上导致并行扰乱。 命令： hagrp -freeze service_group hagrp -unfreeze service_group 为了永久凝固一个服务组，你必须先要打开配置 haconf -makerw hagrp -freeze service_group -persistent hagrp -unfreeze service_group -persistent 为了确定是否一个服务组被凝固显示Frozen(永久性)和TFrozen(零时性)服务组属性对于一个服务组 hagrp -display service_group -attribute Frozen
