No one really could decode the uerf output. Surprise, surprise! But that disk
is essentially an RZ28, and Knut.Hellebo_at_nho.hydro.com pointed out the caveat
in the release notes for recent versions of OSF/DU about adding a SZ_NO_TAG
flag to the entry for the disk in /sys/data/cam_data.c. (For example, see the
release notes for version 3.2C, page 2-7.) I added the flag to
the entry for "DEC DSP". Unfortunately this did not eliminate the error
messages, though it may have reduced them. So the problem is unresolved.
Thanks anyway to Knut and the other who responded.
