Hello, I need to get a crash dump and the only disk controller on the system in question is an eXtremeRAID1100 (DAC1164P) handled through the mlx driver. I'm running FreeBSD 4.7-release + security fixes. dumping to dev #mlxd/0x20001, offset 9372672 dump failed, reason: device doesn't support a dump routine Before I go try to write my own dump routine: Has anyone else already invented that wheel or is the wheel too difficult a pursuit in this case due to peculiarities of this hardware? I've only had a quick glance at the source under /usr/src/sys/dev/ and at first glance the only devices that appear to support crash dumps are aac_disk, ata_disk, ida_disk, and ccd. That last one (ccd) could be a point of interest. Is it possible to create a ccd device from a spare mlxd device? If so, is it also feasible to swap and dump to that ccd device or would it fail because the "real" device didn't support dumps?
