Dear Managers,

sorry for the late summary. Thanks to:

Frank Bos
Nikola Milutinovic
Tom Blinn
Alan Davis
Nick Maniscalco
Emanuele Lombardi

The short answer is that it *should* work. As Nikola Milutinovic and
Tom Blinn point out, there is a block issue (512 vs. 2048) here. The
particular CD-ROM however, is correctly described in /etc/ddr.dbase
as one returning 2048 bytes blocks. Moreover, the system mounts cdfs
cds without problems. Therefore the evidence seems to point to
something wrong with V5.0 in this respect, perhaps in combination
with the drive itself. As Tom Blinn says:

     I can imagine many possibilities, including but not
     necessarily limited to that we have some subtle bug in V5.0
     that wasn't present in the older release (would not be the
     first time), that the newer release is just more sensitive
     to something the drive is doing (or to some defect in the
     media), and so forth.. It *should* work with no problems.

A further mean of analysis would probably be trying a different
drive.

Thanks,

Ettore

-------- Original message.

Dear Managers,

        I installed [*] Tru64 v5.0 (the non-commercial kit) on an
AlphaPC 164SX. It appears it has serious problems when trying to
mount a cdrom with a ufs filesystem on it. Except on rare
occasions when it does mount, I get:

# mount -r /dev/disk/cdrom0c /mnt
/dev/disk/cdrom0c on /mnt: No valid filesystem exists on this partition

# file /dev/rdisk/cdrom0c
/dev/rdisk/cdrom0c : character special (19/54) SCSI #0 CD-ROM
XM- disk #2 (SCSI ID #4) (SCSI LUN #0)

Everything is fine when mounting ISO9660 cdroms. The SRM console
reports the CD-ROM as

dka400.4.0.7.0 DKA400 TOSHIBA CD-ROM XM-5701TA 0167

(the scsi controller is an NCR 810). The funny thing is, the very
same cd Tru64 v5.0 is not able to mount, can be mounted by Linux
as ufs filesystems. Also, v4.0F seems to be less picky.

Any ideas?

Thanks,
        Ettore

[*] One cd displaying this behavior is in particular the installation
one. Booting from it fails, presumably because this problem prevents
vmunix from mounting /. Booting from a 4.0F CD and making an
update installation worked.
