Hello,
This is my first message in this list and also this is the
first time I dig my hands in the FreeBSD kernel.
I got there because I'm building a machine equiped with two
NCR adaptators (Asus SCSI-2000 for exactitude) hooked on a TP55 Asus
motherboard. All of this is drived by FreeBSD 2.2-960501-SNAP.
Boths of the SCSI busses are loaded with hard drives with the
auto spinup feature disabled. Upon system powerup, devices on the
first bus are spined up by the NCR bios: the second adaptater is
leaved aside.
I decided, to correct this to add sinup code in the scsi code.
I've choosen to add this in sd.c sd_get_parans() function. I may be
wrong at that point.
The start of the function looks like this (ommiting variables
declaration):
/*
* Is this unit ready?
*/
if(scsi_test_unit_ready(sc_link,flags|SCSI_SILENT)!=0)
{
printf("Unit is not ready trying to spinning it up\n");
if(scsi_start_unit(sc_link,flags)!=0)
printf("Spinup failed!\n");
return(0);
}
This code almost work: the unit is detected as not ready
(generating errors messages despite the SCSI_SILENT flag) the command
is sent (the unit starts) and then the NCR driver barfs but I don't
know why.
What am I doing wrong? From the boot messages (included
bellow) I guess there is something wronf with command queing. Is it
necessary to wait for the queued commands to complete before sending
the start unit command?
Thanks for your help.
