Thinking about this... 32 commands per host... Hum... As far as CRD's show their
logical partitions in a per-lun-basis, you could have e.g. 3 independend
partitions, each with a 10,6 (*g*) commands-cache...
Ough :( That dynamically things aren't good....
I'll setup a max of 4 in cam_xpt.c and check it out. Possibly a recommended
patch to cam_xpt.c would be to setup this, as far freebsd only supports 8 lun's
by default (afair?). Any chances to get that into 3.4R? Justin? :)
Actual added this to cam_xpt.c:
{
/* Broken tagged queuing drive, 32 tqs per host */
/* changed 12/12/1999 oliver blasnik fixno2 */
{ T_DIRECT, SIP_MEDIA_FIXED, "CMD TECH","CRD*","*" },
/*quirks*/0, /*mintags*/0, /*maxtags*/ 4
},
Cu, Oliver
