BlueSCSI crashes in Initiator mode

[martinborgman]

I am trying to read some OpenVMS disks and one of them crashes BlueSCSI in Initiator mode.

Both disks are Seagate ST34371W disks with Digital (DEC) firmware see below

[SCSI0]
  Vendor = "DEC     "
  Product = "RZ1CB-BS (C) DEC"
  Version = "0818"
  Type = 0
Preallocating image file
Starting to copy drive data to HD00_imaged.hda
[SCSI1]
  Vendor = "DEC     "
  Product = "RZ1CB-BS (C) DEC"
  Version = "0818"
  Type = 0
Preallocating image file
Starting to copy drive data to HD10_imaged.hda

The Disk with SCSI ID 0 works fine bet the disk with ID 1 crashes the BlueSCSI devise.

Also BlueSCSI doesn't crash at the same percentage done on every try.

Looks like it could be an SD Card issue so lets start with the basic troubleshooting here: https://github.com/BlueSCSI/BlueSCSI-v2/wiki/Troubleshooting#what-to-try-first

Specifically doing a full overwrite format with the SD Card Formatter linked in. This is a lower level cell format of the SD Card and addresses many issues.

Second is to grab a second SD card and format the same way and try.

Hopefully that'll get you past this. Let me know how it goes.

As it turns out, it wasn't the SD card at all, it was bus termination.

When I removed both drives from the cage I noticed that the one that was working fine had a jumper on termination enable and the one that didn't work did not have the jumper. I moved the jumper over, reconnected the drive and it worked fine.

These drives are significantly faster than the drives I was reading before. This unfortunately showed the terminator I was using isn't good enough.

This issue is fixed
