Given the relative dearth of DSSI equipment in the NW USA, I hacked in a HSD05 SBB to my VAX 4000/200 so I could use SCSI disks (don't worry - it's reversible. HSD05 module removed from the SBB holder and attached to a plate that fits in the drive sled tracks in the top of the BA430, with a 50-pin pin header soldered into the HSD05 and a loop cable connecting to the backplane at one end and the original backplane->bulkhead connector on the other. SCSI and power brought in via a custom perfboard DIN-96 breakout board. Disks mounted on another "sled plate" and power brought out from the TK70 sled power connector).
Anyway, after a bit of use the first drive (a Sun OEM Seagate ST34371WC) would often fail to boot (b dia100 would go 2.. and then stop), and later it didn't even come up as an option under "show dev". I immediately suspected my DIN96 adaptor board (erm, actually after worrying that I'd blown my HSD05 and turned the 4000 into a doorstop), but replacing the Sun drive with a RZ01-xx 4.5GB unit started it working just fine. Tests of the Sun drive in a Sun have so far come back OK.
And now for the question: Do the HSD devices only work reliably with DEC-firmware disks? Do they require a firmware tweak (such as some CD-ROM drives have, e.g. the SGI drives for 4Ds that pass themselves off as hard drives so the PROM will boot from them), or was this just one oddity?
So in general I shouldn't need to worry about keeping a stock of true-(beige? burgundy?) DEC disks around as replacements. Good, makes it a bit easier. I'm running v7.3, so SCSI support should be good. How much of the SCSI-ness is exposed to the VAX, though? It sounded like the HSD05 took care of much of that.
I've never really run an HSD05 but I have run systems HSD10... VERY fussy on the disks it will "see"... 4.3 GB and below in the putty color bricks. I have also run SE scsi on an MV4000-100A to a BS35x storage shelf... it only sees half the slots(every other one) but allows you access to at least 18GB disks :-). I've been buying the dec bricks on eBay for quite some time for $10 plus shipping... not worth the time or potential data loss in making non-dec firmware disks work.
malmberg December 12 2017 HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.
nmbonao December 08 2017 Is anybody knows OpenVMS 8.2 version downloadable version? or CD copy? Thank you very much
