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.

Re: disable TOC reboot

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.

Re: disable TOC reboot

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