Subject: Error messages from SCSI disk

I have 4 Hitachi D516C SCSI disks (1.3 GByte each) attached to two
different machines: a Hyundai HWS-S210 SPARC2 clone and an ELC.  I get
SCSI error messages like this:

Oct 14 01:04:00 bribri vmunix: esp0:    Target 3 now Synchronous at 4.0 mb/s max transmit rate

The SCSI cables have been shortened and are correctly terminated.
There are no address conflicts.  I am pretty sure this is a software
problem because I have no evidence of corrupt copies so far.  It is
annoying because each reset hangs the machine for 20 seconds or so.
Does anybody know of a patch to Solaris 4.1.1 which fixes this
problem, presumably with a longer time out?

Subject: Question about Sun Token Ring card

Date: Thu, 8 Oct 1992 20:30:54 GMT

I am about to buy a Sun Token Ring adapter card. In order for
the card to work with my Ring it should have 5 Volts DC available
on pins 3 and 8 of the 9 Pin connector on the card.  Does anyone
know if this voltage exists? Is there some technical hotline I
can call to find this out?  The voltage I am talking about exists 
on IBM manufactured PC cards.  The Token Ring MAU (I have special ones)
derives	its power from these pins. So unless the Sun card provides 
the same voltage I can't hook up my Sparc to the network and my
research will be held-up.....

Any help will be greatly appreciated and thanks in advance.

Both responders are close, but not quite right.

Double-slot (i.e., older) GX boards are 1152x900 at 66Hz only.

Single-slot (i.e., newer) GX boards are multi-sync and support 
1152x900 resolution at either 66Hz or 76Hz.  There are no switches; 
the board "automagically" syncs up with the monitor.

The newer Sun monitors are also multi-sync and will also 
"automagically" sync up with the frame buffer.  If a multi-sync GX 
is combined with a multi-sync monitor, the combo will default to the
higher refresh rate (76Hz).

The GXplus is capable of 1152x900 at 66Hz or 76Hz, or 1280x1024 at 67Hz.
Which resolution and timing will happen by default with which monitor
is more complicated than I care to go into here.

So, transfer speed/access latency are not unimportant,

I have a Tektronix Phaser II color printer (postscript) connected to a network
of Sparc2s.  Unfortunately the color which appears on the screen and the color
on the hardcopy output match very poorly.  Some experimentation has revealed
that the majority of the problem seems to be coming from the fact that the Sun
is not displaying the colors correctly, based on examing pure samples of the 
primaries.  This doesn't seem to be something that can be adjusted in the Sun
hardware, but I need to be able to get good looking results from the same image
on both the screen and the printer.  

I've seen products that compensate for problems like this advertised for the 
Mac.  Can anyone point me at something similar for Sun systems?

Subject: Switching a WangDAT 4 mm tape into "non-compressed" mode
Organization: Boston Business Computing, Ltd.
Date: Mon, 12 Oct 1992 21:55:12 GMT

Our new WangDAT 4mm tape drive has the ability to write tapes in either
compressed (3+ GB) or uncompressed (1 GB) formats.  We need to be able
to occasionally write uncompressed tapes, but can't find a reliable way
to switch the tape into uncompressed mode.

I'm using a modified entry for /sys/scsi/targets/st_conf.c which came
over the net a while ago.  It was necessary to get the full speed from
the drive.  I've duplicated it below.

---------------------
/* WangDAT Model 2600 3.81mm helical scan cartridge */
{
	"WangDAT 3.81mm Helical Scan", 7, "WangDAT ", ST_TYPE_EXABYTE, 512, 
	(ST_BSF | ST_VARIABLE | ST_BSR | ST_LONG_ERASE | ST_AUTODEN_OVERRIDE),
	5000, 5000,
	{ 0x13, 0x93, 0x00, 0x00, },
	{ 0, 0, 0, 0 }
}
---------------------

As you can see from above SCSI code 0x13 selects non-compression and
0x93 selects compression.  So, now I can access two tapes -- /dev/rst1
(uncompressed) and /dev/rst9 (compressed).   Unfortunately, the drive
refuses to write low density tapes if they are already formatted as
high density and vice versa.  If the tape is brand new then it is
formatted correctly.

This is almost what I need, but I'd like to be able to switch back and
forth between the two formats when I need to.  Does anyone have any
experience with this?  Will I have to bulk erase the tapes to switch
between compressed and uncompressed?

>The IPX by definition has a SPARC2 chip,

Actually, no, it doesn't.

"A SPARC2 chip" presumably means the integer unit chip and maybe
floating-point unit chip in a SPARCstation 2; the SS2 has a 40 MHz
Cypress 7C601 as its IU chip and, at least according the tables in
Appendix L of the SPARC V8 manual, as incorporated into "whichiufpu", a
TI TMS390C602A as its FPU chip.

An IPX has, according to the results of "whichiufpu" and an article in
*Microprocessor Report*, a 40 MHz Weitek W8701 or Fujitsu MB86903 as its
combined IU-FPU chip.  (An ELC has one of those same chips, but runs it
at 33 MHz.)

I suspect the Cypress chip, and the Weitek or Fujitsu chips, give
roughly the same integer performance at 40 MHz (I don't have the SPEC
numbers on them handy, but I remember the SPECmarks being fairly close);
dunno about the floating-point performance.

Neither of those are, however, a TI TMS390Z50, a/k/a Viking (which has
IU, FPU, *and* memory-management unit on the chip).

SunExpress isn't going to help in this case.  They sell consumables.  This

This is a story of a single tape, so it's not statistically sound, but
it is a data point: I recently retired a Sony P6-120MP video tape (not
data grade) because it was starting to regularly get enough write
retries that the driver would complain about them at close time.

I had been using the tape for daily backups about 4 days a week for
more than 2 years, so the section of tape at the beginning of the reel
had been written on at least 400 times, probably closer to 500.

I think something as simple as:

should work, assuming cg6 and bw2 are what you've got.

One really cool thing I like to do is run:

openwindows -server /usr/openwin/bin/xnews-rfx -dev /dev/rfx0

Has anybody succeeded in making their own adapter so they can use
serial port B on an SLC or ELC?
We'd like to use the ports on most of our ELCs, but we don't want to
pay the ludicrous price Sun is charging for the cable -- we could use
the money elsewhere.

As far as I can see the only mention of the pin-outs is on P.166 of the
ELC Installation and Repair Guide, and it doesn't really help (I'm not
an electronics genius...). Connecting pins 2 and 3 on the serial port
to 3 and 2 on the output gives a usable DTE cable for port A, but
connecting pins 14 and 16 to 3 and 2 doesn't give a similar result for
port B. I probably have to do something with the CTS and RTS signals
for the two ports, but what?

Thanks for any input.

Regular 8mm video cleaners *are* abrasive by nature, and should not be used
in Exabyte drives. The video cleaning tapes even warn they are abrasive in 
the fine print on the wrapper.

We get ours from IBM, 12-time tapes. Wouldn't the difference in the number
of cleanings be directly related to the amount of tape on the cartridge? If
so, it could easily be the same type of tape in all of them, and the same
degree of cleaning.

To summarize the responses to my original posting about whether this fluid
cleaner was better or worse than the dry tapes, the answer seems to be that
Exabyte themselves used to sell this fluid cleaner but for various reasons
(environmental considerations & PR, tests indicating the fluid evaporated 
before the tape got to the heads, customer misuse, etc.) discontinued it.
One person said Exabyte has been specifically not recommending it.

At any rate, based on the information I got, I don't plan to switch from the 
dry tapes. Exabytes do take a long time to load a tape, the fluid is very
volatile, and I can easily believe there wouldn't be much left after 20-30
seconds.

As far as I know, there are 66Hz and 76Hz GX's. The old double-slot GX
certainly is 66Hz, the newer one-slot GX is 76Hz.

I've got a 76Hz cg3 in my IPC. From the boot monitor, I selected the
other Xtal. The cg3 operated nicely in 66Hz mode then (although I
prefer 76Hz). If the GX+ has more than one Xtal, it can probably
also run on lower refresh rates.

The info on the cg3 registers are in /usr/include/pixrect/cg3var.h in
SunOS4.0.3c, but they removed the info in 4.1.2.
