ES45 Alpha Server with Tru645.1b and KZPCA scsi adapter

[Alice Daniel]

Driver (new hardware driver) help for an ES45 Alpha Server running TRU64 v5.1b OS.

I have a SCSI adapter, the KZPCA-AX installed on my system, with single-ended output.
Has anyone had any experience getting this card to run with a single-ended device?

In the supported options list, the actual card listed is KZPCA-AA. Is this difference from the AX and if so, why?

The driver I have for my unique device has a problem when using the "CAM_DIS_AUTOSENSE" option.

I think they are both the same, the -AX could be a newer version, but should be compatible.

Partnumbers are:
KZPCA-AA
SN-KZPCA-AX
146094-001
103385-001

What is the problem you get with the driver?

[Alvaro Ivan]

Usually parts ending in -AX are spare part numbers, and -AA are Option part numbers, so these two are exactly the same.

Learned something there .. thanks.

I have another one for you:

parts ending on -.X (AX/BX/CX) are single ended SCSI, parts ending on -.Y (AY/BY/CY) are high voltage differential SCSI. For example KZPBA-CY = diff. SCSI, KZPBA-CX = single ended.

On the REQUEST_SENSE command, I set up the cam_flags to be CAM_DIR_IN | CAM_DIS_AUTOSENSE. When the request sense cmd is initiated, I get the error msg from ccmn_ccb_status function: CAT_CCB_ERR (0x08) cam request invalid.

When I remove the CAM_DIS_AUTOSENSE from the cam_flags setting, the OS panics and crashes on the request sense command.

The KZPCA-AX card I have installed does not have a method (through the bios) to manipulate the enable or disable the AUTOSENSE.

I am not into programming myself, but it sounds possible that the error message you get is because you use the wrong command? What i mean: you use request sense only after an error has occured and you want more info on the status of that. If you want device info you should use mode sense. If you mixed these two up it would be logical that a request sense returns an error because there was no error before the command was issued.

I found the following documentation (you probably have it yourself) here:
