I've not yet tried the drives with a recent version of 'ahc'. The
hardware is kinda buried in a rack right now.
If I had to guess at the difference I'd say that this bit of code from
sym_hipd.c is the reason for the difference:
static void sym_sir_bad_scsi_status(hcb_p np, int num, ccb_p cp)
{
...
/*
* Now deal with the SCSI status.
*/
switch(s_status) {
...
case S_TERMINATED:
case S_CHECK_COND:
/*
* If we get an SCSI error when requesting sense, give up.
*/
if (h_flags & HF_SENSE) {
sym_complete_error (np, cp);
break;
}
...
I'm mostly guessing at this point though.
