Subject: Replacing 1542B by 1742A in NetWare server without formatting?
Date: 12 Jan 93 14:43:58 GMT
Followup-To: comp.periphs.scsi
Organization: /WW/ai-gate/home/webus/.organization

Hi netters,

we have a new Novell Netware 3.11 Fileserver with a 486/50DX EISA CPU
and 32MB of RAM.  Currently we are are using two Adaptec 1542B host
adapters (for some historical reasons) for duplexing 4 SCSI-drives
(Maxtor XT-8760S, Seagate WREN CDC 94191-15 and 2 * Micropolis
1528-15). Do we have to format all drives when we replace the 1542B's
by 1742A's (running in enhanced mode)? Can we expect a performance
boost by doing that?

Thanks 
Thomas Weber

	I suspect that the Mac is only scanning early on.  Some SCSI drives
ignore the bus for up to 10-15 seconds (Seagates are renowned for doing this,
to the point that the "slow boot" jumper on Amiga SCSI controllers is often
called the "Seagate jumper").  This is allowable under the spec, though the
spec recommends that they at least return BUSY 250ms after powerup/reset.

	Have you tried warm booting?  Sometimes they come up faster from a
warm boot.  Is there some way to slow down the mac's boot? (I doubt it).
The only other option would be to get an external box, put the drive in it,
and power it up before the Mac (you might have to cut the reset line as well.

I have not been able to get ASPIBIN nor ASPITAPE to work regardless of the

the default timings are an on time of 11 and an off time of 4, Adaptec
notes that 11 may be too high for some drives to stream, however I don't
think that is the problem here, since the above programs seize where the
Novaback doesn't.

The ISA busmastering SCSI controllers (Adaptec 154x, BusLogic 54x and
WD7000) all run at at controller->host transferrate well below 10MB/s.
They are also not fast SCSI. Better ISA boards generally allow the
1540 to use a 6.7MB/s transferrate.

The AHA174x and BT74x series EISA controllers are able to handle
10MB/s. The AHA174x and BT747 can handle 10MB/s SCSI transfers.

Subject: Interactive Unix w/ SCSI Install problem
Date: 5 Jan 93 16:07:09 GMT
Organization: Auburn University Engineering

My system configuration is as follows :

486-50 DX
16M of Ram
Adaptec 1542 SCSI Controller
Fujitsu 520M SCSI Hard Drive
Video 7 1024i Video Card
Generic IO Card for serial/parallel ports
Wangtec tape Drive and card (non SCSI)

I had Interactive Unix running on my 386-33 w/ IDE controller, but I am
having trouble getting it to run on my new system listed above.  I run the
install program and do the install from tape (I have tried installing from 
the disks also and the results were the same).  It partitioned the drive
correctly and copied everything to it, but when I reboot the machine, it 
doesn't boot UNIX.  If UNIX if the only OS on the drive, I get "non system
disk or disk error" message.  If DOS is in partition 1 and UNIX in 2
(regardless of how the active partition is set, it boots DOS.  If UNIX is in
1 and DOS in 2 the system checks drive a and then just sits there and
does nothing.

BTW, After I installed from tape, I did comfigure a new kernel w/ the 
Adaptec Driver in it set up as the Boot Device.

And an install from the floppy disks does the exact same thing.

Any suggestions?

	A lot of vendors have problems like this.  We found them because
Amigas are commonly ready to access their drives within <1-4 seconds of
power-on or reset.  So long as the drive is nice and at least returns BUSY
we'll wait for it to initialize itself.

	We had to add a switch to make the driver delay 15 seconds before 
scanning the bus to support a fair number of drives.

I also had colour/flicker problems on my 1200. On the kickstart screen the disk
animation would flicker, in fact, anything moving on the screen would flicker
with black and white bands across the screen. Finally the 1200 gave up and the
kickstart screen went pink(!). Luckily the shop I bought it from gave me a new

	Start with having to have 8 copies of all the r/w channel hardware,
8 banks of ram (well, maybe less, but almost certainly more than 1), etc, etc.
Plus the PCB space for all this hardware.  $$$$

	Of course, drives have been made in similar ways in the past. I can't
think of any recent ones.  There was one drive that had two sets of arms, but
I don't know if it had two sets of control hardware.

Don Lancaster, author of the column Hardware Hacker, and writer
of many articles on the use of Laserwriters and Postscript
had a method for doing such a thing.

Basically it reserved blocks of free space at a know location
on the laserwriter's SCSI disk.  This was done by writing
temporary files to the disk right after initialization.
The the fonts and other files for use by the laser were
installed.

To use it, he used the SCSI device to load a document to
the SCSI drive.  He had to use this 'known location' hack,
because in operational mode he can access block scsi I/O, but
not the file system on the laser writers SCSI disk.
Then once the data is in the known location, he could tell
the printer to print the document that was stored in that
'known location'. 

So instead of having to force his entire postscript file thru
a serial port, he used SCSI to get the data out to the printer
and then just had to send the 'do it' command via the serial
port, at a great savings in time.

You can download the details on GEnie's PSRT Postscript Round
table libarary.

I believe that other apple printers take their commands direct
from the scsi bus too, the cheaper, non-postscript ones.

As far as I know it's the only VL-BUS SCSI HA available right now.
Please correct me if I'm wrong.  Anyways, I like it.  It's fast.

  Good, reliable drive.  We used them in RS6000, Sparc and Netware without
any problem.  They are a little slower and much noisier than the new

It plugs right in and runs without problem so far (about 1 year).
Its size is just below the wraparound zone where older versions of
software self destruct with larger drives.

Heat and noise are about average, somewhat noisier than a Wren V on seeks.
The seeking sounds make the drive seem faster ("COMPUTING clickitta ...").

There seems to be some confusion about the type and amount of buffering
on the drive.  Or at least there was when I bought mine a year or so ago.
Of course the more aggressively the drive is buffered, the greater the
mess if you lose power or otherwise crash Unix.
