You probably want dumpadm(1m) for this, actually. That, and savecore(1m). Crash dumps should already be enabled by the OS setup utility; dumpadm should confirm that for you. As for the original problem, I'm not sure. You clearly are having a problem between your SAS HBA and one of the targets; you can try to decode those codes using the information in the mpt_sas header files. As a result of that problem, the HBA's I/O controller was reset. I do not know why or how that induced a panic; hopefully that information can be gleaned from the crash dump. If you want to debug it yourself, run savecore on it and then mdb <number>, where the number is the highest-numbered crash dump present (i.e., vmcore.3 -> mdb 3). Also, if it's the same target every time this happens, you probably have a bad disk or possibly a bad disk bay. Replacing that device may work around this by avoiding the trigger for the bug (it's still a bug, though). > > On Nov 27, 2014, at 12:17 PM, Len Weincier via smartos-discuss > > <[email protected]> wrote: > > > > Hi > > > > We have a host with some decent supermicro kit that has spontaneously > > rebooted twice in the last week under normal conditions.
