Not if you explicitly want to change it w/o recompiles.

We all know Quantum F/W if flakey..
I put the latest (d01) patches and and used the sym driver instead and
did 64 tags for the linux side and put a much heavier load on both sides.
What I get now at least once was:
scsi : aborting command due to timeout : pid 112110, scsi1, channel 0, id
4, lun 0 Read (10) 00 00 89 58 da 00 00 52 00
sym53c8xx_abort: pid=112110 serial_number=112157
serial_number_at_timeout=112157
scsi : aborting command due to timeout : pid 112111, scsi1, channel 0, id

sym53c8xx_abort: pid=112111 serial_number=112158
serial_number_at_timeout=112158
sym53c895-0: abort ccb=c325f000 (cancel)
scsi : aborting command due to timeout : pid 112109, scsi1, channel 0, id

serial_number_at_timeout=112159
sym53c895-0: abort ccb=c2fc2000 (cancel)
SCSI host 1 abort (pid 112109) timed out - resetting
SCSI bus is being reset for host 1 channel 0.
sym53c8xx_reset: pid=112109 reset_flags=2 serial_number=112159
serial_number_at_timeout=112159
sym53c895-0: restart (scsi reset).
sym53c895-0: Downloading SCSI SCRIPTS.
sym53c895-0-<4,*>: FAST-40 WIDE SCSI 80.0 MB/s (25 ns, offset 31)
The other side (still Solaris) sees:
WARNING: /pci@1f,4000/scsi@4/sd@4,0 (sd162):
SCSI transport failed: reason 'reset': retrying command
I don't see a gap in transfers from the Solaris side. It's also now true
in this configuration that the Solaris side has lower priority (at ID 6).

Next on my list... I'm running wads of tests right now. When the
complete, I'll rehook the UltraLinux.
