SG is not switching to next node.

Hi All,

I am new to VCS but good in HACMP.

 

In our environment we are using VCS-6.0,

I one server we found that the SG is not moving from one node to another node when we tried manual failover using the bellow command.

hagrp -switch <SGnamg> -to <sysname>

We able to see that the SG is offline in the currnent node but it's not coming online in the secondary node.

There is no error locked in engine_A.log except the bellow entry

cpus load more than 60% <Secondary node name>

Can anyone help me to find the solution for this. I will provide the output of any commands if you need more info to help me out to get this trouble shooted Smiley Happy

 

Thanks,

Issue could be Preonline

Issue could be Preonline script so you could test if this is being called by amended preonline script (in /opt/VRTSvcs/bin/trigger) to create a file so you know if it is being called.  If Preonline is being called then issue is with preonline script.  Also you could just try disabling preonline (set PreOnline = 0 and remove PREONINE from PreOnline = 1 in your group attribiutes).

But your main.cf does not correspond to the log as the main.cf contains group mdwapd2_sg, but log says ora_sg_01, and the system names are different too, so please send correct main.cf

The log also says the mounts have to kill processes (looks like WebLogic), so any processes running in the mounts should be brought down cleanly by putting app under VCS control.

Hi,

engine_A.log would be the place I would look in, if possible, attach the engine_A.log here. There will be entries around group been taken offline & then starting to online on other node ...

Hi Mike, Thanks for your

Hi Mike,

 

Thanks for your suggestion, The fault is due to preonline script, The server is not having enough resource to bring the SG online so it's stoping the SG to come online.

Thanks for your help, I will have more doubts in future Smiley Happy

 

Thanks,
