Storage: V6.2 3rd party SCSI problem
The Question is:
I'm facing a Disk problem on a DEC 3000/400 AXP machine.
I have a Fujitsu M2934SAU 4Gb external Hard drive that works fine
on VMS 6.1. When I try to use it on the same machine, booted in
VMS 6.2 I'm unable to mount the drive : I get a message
requesting operator assistance, and there are continuous
accesses to the disk until I do power it off.
What did you change between VMS 6.1 and VMS 6.2 that makes my
disk unrecognizable to VMS 6.2 ?
Thanks in advance.
The Answer is:
OpenVMS V6.2 makes use of SCSI-2 messages to dynamically configure the
SCSI device. You'll want to check with the drive vendor to see if the
drive vendor supports the full SCSI-2 command set, and with your hardware
support organization to see what support they can offer.
If the drive is visible as a "DK" device under OpenVMS, the V6.2 tool
SYS$ETC:SCSI_INFO can be run against the drive -- this tool can be used
to see what (if any) SCSI problems might be present.
The most common source of these problems is an incorrect response to
the (10 byte) SCSI mode sense command.
In this particular situation, OpenVMS engineering is looking at a
previously-reported problem specific to the Fujitsu M2934SAU drive.
