#A2060, Envoy and GVP

To those (Eric and Chris) who've had problems with the A2060 and Envoy: what SCSI controllers are you using? An Envoy user called today to say that he was having lockups when transfering large files with Envoy and an A2060. The problem disappeared when he stopped using a GVP controller and went to a 2091. The problem was also worked around by patching the driver to reduce the MTU (use a raw editor to find and change "250000" to "25000," for example — a higher number still less than 250000 might work, too).

I'm using the MacroSystems WarpEngine in my 4000. It's using the SCSI-II 'warpdrive.device' built into the acc. Could you give me some more details on how to locate this MTU (?) value? When you refer to 'driver', I assume you mean 'filesystem.service'? Thanks! Erik Flom

Darn. I doubt the Warp suffers the same problem. Oops. In case it helps, the kludge is to fix the value contained in your A2060 driver (libs:networks/a2060.device), not filesystem.service or any other Envoy file. Dale L.

'Darn.' …My sentiments exactly! As far as editing the a2060.device, I should replace '250000' with ' 25000'? (I'm assuming there's only one instance of this in the driver? :^) Thanks, Erik Flom

The A2060.device should have one and only one occurance of "250000" that someone decreased to "25000" to make his problem go away. I haven't tried it, but thought you might want to know. Dale L.

If I convert '250000' to '25000' what do I fill the missing char in the file with? ie: ' 25000', or '25000 ' Thanks, Erik Flom

I haven't done it, but I'd think 025000. Dale L. Larson Intangible Assets Manufacturing (info@iam.com) "That's the best part about being crazy. You see things no one else can see."

Thanks! P.S. What do you think of the fact that it _always_ seems to hang at around 85MB? Erik Flom

Don't know. Am trying to look into it. Dale L. Larson Intangible Assets Manufacturing (info@iam.com) "That's the best part about being crazy. You see things no one else can see."

I'm using the builtin IDE interface in the A4000/040-25, and the builtin SCSI in the A3000/030-16. In both cases, my scsi.device is in ROM. Is that MTU number the "MaxTransfer" factor (or "MaxFactor" heheh :-)? I tried searching devs:networks/a2060.device for ASCII "250000" and HEX 0x3D090 and found nothing. -Chris

Chris, did you try 0x250000 ??? Just a thought. The Four Seasons of Southern California: Fire, Flood, Earthquake, and Riot.

"did you try 0x250000 ???" Yep. -Chris

I have a 2091 on one machine and a GVP 40 Mhz 030 comb board on the other… am I hosed?? I don't mind hacking a bit as a work-around, but I would like a slightly more stable permenant fix! Is it my imagination or do an awful lot of GVP products need extra help?? Bill… on Autopilot in Womelsdorf 😉

I'm looking into what I can do, but I didn't write the A2060 driver, I don't sell the A2060, etc., etc. Look for more info about the A2060 in a few days. Dale L. Larson Intangible Assets Manufacturing (info@iam.com) "That's the best part about being crazy. You see things no one else can see."
