i dont know how the mt usage snuck in. what i meant to say was:
implement the DIOCGCACHE and DIOCSCACHE ioctls in mpii for raid volumes because its firmware doesnt handle the relevant mode page changes to do the same thing. this allows sd(4) to enable the write cache on such a volume on attach, like we do in mpi(4) and on normal scsi devices via mode page tweaks. cheers, dlg On 21/02/2011, at 7:36 PM, David Gwynne wrote: > CVSROOT: /cvs > Module name: src > Changes by: [email protected] 2011/02/21 02:36:15 > > Modified files: > sys/dev/pci : mpii.c > > Log message: > usage: mt [-f device] command [count] > > most of the work and bug fixes were done by mikeb@, i put it in ioctl > form. > ok mikeb@ and miod@ > tested by me > an earlier revision was tested by Eukasz Czarniecki who also reported > the problem in the first place.
