rhel 5 cluster problem...........

Viral Ahire — Wed, 26 Aug 2009 07:33:06 GMT

Hi ,
I have configured 2 node cluster (redhat cluster suite)with Proliant 580G4 servers and MSA500 storage.
Cluster configured on RHEL5 64bit os.
Now the problem is ,when i stop cluster application (oracle), then the node where the application was running ,is leave cluster and it's cluster service stop and reboot server due to fencing.
HP-ILO is used for fencing.
I have attached logs and cluster.conf file...

Please help to solve this problem....

regards,

It looks like your stop script needs some checking. It should return 0 value if the database was stopped sucessfuly.

Jun 30 11:21:03 psfhost1 clurgmgrd: [3767]: script:Oracle: stop of /etc/init.d/orcl failed (returned 127)
Jun 30 11:21:03 psfhost1 clurgmgrd[3767]: stop on script "Oracle" returned 1 (generic error)

There you can see that ths script "Oracle" returned 1.

You must ensure that your start and stop script is working correctly before using the cluster commands.

Shalom,

Any time a script called by the cluster returns a return code other than 0 (zero).

It is game over for the service.

Often you will need to customize the script.

RHCS also does a service stop on the service at start up, even if the service is not running.

The start up script must be modified to detect this condition and return code zero when it occurs.

Hi lvan,

I can start/stop oracle manually. even right now cluster is working with oracle in live environment. but problem occure only when you try to stop cluster app (oracle).So currunt cluster setup will not usefull during failover situation.

Actully the problem is, my 2 node cluster was working good ,but i starting facing this problem after changed hostname and ip address of both nodes. due to this changes i had to reconfigur cluster (through system-config-cluster).

Please help to resolve this problem.............................
