disable TOC reboot

Is there a way to disable the TOC reboot of a node if it loses communication with the cluster? I want to troubleshoot communication problems of a test cluster, there is no shared storage so no risk of split brain and data corruption. NODE_TOC_BEHAVIOR in cmcluster.rc defaults to reboot, the only other option I see is panic.

Shalom,

No.

TOC is critical to prevent split brain syndrome corrupting your shared data.

Hi John,

To troubleshoot communication problems, instead of trying to deactivate TOC, you may try tcpdump or any other IP traffic sniffer (Ethereal, ...)

Good lcuk.

Those that you see are the only two options. With the panic you should be able to set up a dump.
