Thanks people,

    Once again you have performed your Kirkian duty and saved the
universe ( or was it humanity ) from destruction. As usual most of
the replies arrived before my post did. As usual I am sorry for taking
so long to reply. But the news is GOOD.

My original posting:

The replies were of three main varieties:
     1. Let me know what you find out.
     2. The drives work fine under 4.1.1, and should work under 4.1.2.
     3. We have a 6X0MP system and the WREN{V,VI,VII,VIII} drives work

About 30% of the replies were of variety 3! More than statistically
adequate, my friends. There were several comments about the true
meaning of 'not supported' ranging from straight forward to highly
subjective. ( I think the quote was "pissing down your back and telling
you it's raining".) There were also several comments about the
inadequacy of the format.dat entries provided by Sun for these drives.
( of course they are 'not supported', so why should we believe those
entries anyway ?) And there were a couple of reminders about recreating
filesystems ( re-newfsing, is that a real word?) because I'm going from
4.0.3 to 4.1.x. TFM says this is not required, but the comments were
that I would be losing some performance if I did not.

I have not done the upgrade yet, due to VME issues, but
these are almost resolved. I will be doing the upgrade in about two
weeks. I'll be happy to respond to anyone who would like to hear my
continuing upgrade saga.

Thanks to All: ( hope I didn't miss anyone )
