Here are the steps:
Before the system is hung: # mdb -K -F <-- this will load kmdb and drop into it Don't worry if your system now seems hung. Type, carefully, with no typos: :c <-- and carriage-return. You should get your prompt back Now, when the system is hung, type F1-a (that's function key f1 and the "a" key together. This should put you into kmdb. Now, type, (again, no typos): $<systemdump This should give you a panic dump, followed by reboot, (unless your system is hard-hung). max _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
