Understanding RestartLimit for non critical ressource
Hello, we have some trouble with our oracle listener process. sometimes the listener is killed by vcs. We dont know why. xxx VCS ERROR V-16-2-13027 (node1) Resource(lsnr-ORADB1) - monitor procedure did not complete within the expected time. xxx VCS ERROR V-16-2-13210 (node1) Agent is calling clean for resource(lsnr-ORADB1) because 4 successive invocations of the monitor procedure did not complete within the expected time. xxx VCS NOTICE V-16-20002-42 (node1) Netlsnr:lsnr-ORADB1:clean:Listener(LISTENER) kill TERM 2342 xxx VCS INFO V-16-2-13068 (node1) Resource(lsnr-ORADB1) - clean completed successfully. xxx VCS INFO V-16-2-13026 (node1) Resource(lsnr-ORADB1) - monitor procedure finished successfully after failing to complete within the expected time for (4) consecutive times. xxx VCS INFO V-16-1-10307 Resource lsnr-ORADB1 (Owner: unknown, Group: ORADB1) is offline on node1 (Not initiated by VCS) However,Resource(lsnr-ORADB1) is set to non-critical, to prevent an failover. I'll now set an RestartLimit forResource(lsnr-ORADB1) to let the cluster try to restart the listener, but what happen if this failed?Will the Ressouce still staying offline or initiate the cluster an failover for the whole ResourceGroup? thanks in advance for any help!
VCS clustered Enterprise vault migrate index service to new node
Hi, We have three node cluster for Enterprise vault in Veritas Cluster server, the node details are as follows: Node 1: EV server with all services Node 2: SQL server Node 3: Spare server for EV service failover and SQl service failover. Also GCO and VVR is configured for SQl server and EV server volumes are replicating using VVR but are not in VCS control. Now we want to remove index service from EV server (node 1) and add it to new server, also add new server to the cluster. Can anybody share the steps we should follow from VCS end to perform above changes.Volume is mounted on two split-brain nodes in VCS 6.0
I have built a three-node cluster using vcs 6.0 in sles 11 sp1.

Apache is brought up in vcs1. But when I check vcs3, the mount point still exists . And after several minutes, a kernel panic occur in vcs3. I think it is very dangerous thatavolume is mounted on two split-brain nodes . How can I prevent this happens?
