SCSI compatibility mode

Steve Woloszyn — Thu, 01 Mar 2001 17:19:10 GMT

Can I configure a SCSI adapter/target to run in compatibility mode (HP-UX 10.20/11.00) ? i.e.:
- disable wide SCSI
- disable tagged queuing
- enforce synchronous transfer
- lengthen timeout period
- etc.

I seem to recall Sun-Solaris allows a user to do this; e.g., configure isp driver for SunSwift PCI-SCSI adapter:
file: /kernel/drv/isp.conf
edit: scsi-options=0x78;

What is the HP-UX equivalent ?

You can test with SAM (Kernel drv).

You can adjust the scsi setting by interrupting a boot. Then go to the SER (service) menu. Type in scsi and you will see the settings for all of your cards. then try scsi help to get the details.

This sounds like a very good solution (7 points), however, my C-class machine does not have this SCSI option available from the SER menu. I will assume a software solution is not possible, and, continue on the SER theory. Thank you.
