Query regarding one vcs node down
Hi Team, Please suggest, if I have 4 nodes and due to some network issue suddenly all 4 nodes down. 3 nodes came up but 1 node is not coming up. So what would happen to vcs services.Does that run automatically or need to run it manually. Please share the step by step activity. Thanks.

Hi Team, Many times we face resource faults alerts on our AIX server,but when we check it shows all are running fine. Also, when checked logs it shows not (initiated by VCS) alerts. Our main concern is to troubleshoot, why we get these alerts and if we get these alerts then why cluster resource is not showing faulty.

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 :) Thanks,Solved1.8KViews1like8Comments
