The question:
------------------------------------8<------------------------------------
I've got a Netra i4 with Solaris 2.5.1. It has an external box with a 2 Gb
Quantum Fireball TM hard disk and a 2 Gb HP DAT. It works just fine most of
the time, except when the following happens:
WARNING: /iommu@0,10000000/sbus@0,10001000/espdma@4,8400000/esp@4,880000
0 (esp0):
Disconnected tagged cmds (15) timeout for Target 5.0
WARNING:
/iommu@0,10
000000/sbus@0,10001000/espdma@4,8400000/esp@4,8800000/sd@5,0 (sd5):
SCSI transport failed: reason 'timeout': retrying command
WARNING:
/iommu@0,10000000/sbus@0,10001000/espdma@4,8400000/esp@4,8800000/sd@5,0
(sd5):
SCSI transport failed: reason 'reset': retrying command
then, the hard disk thinks for a while (somewhat less than a
minute) and resumes working.
This failures are very unoften; the last one happened on a period
of very low activity, some minutes ago (just one or two users were using
the proxy cache, which resides in this disk).
Any clues besides cabling and the like? I have already checked
that. Ah, yes, the parameters:
# New disk/partition type saved on Thu Dec 5 22:14:38 1996
#
disk_type = "QUANTUM-FIREBALL_TM2110S-300N" \
: ctlr = SCSI : ncyl = 6483 : acyl = 2 : pcyl = 6485 \
: nhead = 4 : nsect = 159 : rpm = 4500
partition = "sda2" \
: disk = "QUANTUM-FIREBALL_TM2110S-300N" : ctlr = SCSI \
: 0 = usr, wm, 0, 4123188 : 2 = backup, wm, 0, 4123188
They were guessed by John DiMarco's scsiinfo (thanks, John).

The answers (short):
- Disable tagged queuing
- Cabling problem, esp. length
- DAT drive must be at the end of the chain; remove slick active
terminator.
- Sun patch 101378
- Plain incompatibility
