The VA7xxx series is a product of HP StorageWorks, a portion of Compaq
that HP acquired during the merger. It has produced some very nice
products for quite a while now. The mass storage stuff is really
excellent. I am at a loss to say the same about their tape libraries.
I am actually quite impressed that HP was able to provide MPE support
for this mass storage equipment, even though it was done after the EOL
announcement for the HP 3000. The biggest problem MPE users have with
this equipment is a version problem. There has to be some patches
installed on 6.0 or 6.5 to make this device work. Once you have that,
it is pretty straightforward. But the other problem on MPE, is a lack
of understanding what such an array can do. MPE people are more used to
a one-to-one relationship between device and Ldev or volume. With the
virtual array, this relationship disappears, everything is, well,
virtual. LUNs are also foreign to the MPE universe, but once these
concepts are understood, everything falls into place.
Perhaps this should be a thread on this list, or better yet, a session
at the Symposium or HP World. After all, these storage devices are
going to be critical for homesteaders.

Sounds like Neumann is an honest person from HP, but what does this tell
you
from what he does say? << I will admit I have not much idea of

but I am

This is a product that HP created correct? Maybe I am wrong, I have been
wrong before but what I can tell you is HP strains to help it's
customers
understand what they do not understand themselves and we all pay bigger
buck
than before since the gene pool at HP has depleted to the point that HP
cannot even spell HP3000.
This is not intended to pick on you as an individual since I have seen
many
helpful postings from you and know you really care, IT's YOUR COMPANY
that
Stinks
David is only one customer of a minimum of 5 that I have seen having
problems from HP trying to understand/install/train on the VA7XXX disks.
So why don't we get HP to post documents on "how to install on an HP3000
/
configure and maintain these VA7XXX units. They have them for HP-UX.

I will admit I have not much idea of CommandView, but I am
speculating that what it tells you about the LUNs are the
percentages of the overall VA's capacity being used by
these LUNs.
I.e. 7% + 3*17% = 58% of the VA's capacity is used by these
4 LUNs.
Sort of fits, since your LDEV 1 LUN is apparently 4GB and the
other 3 are 9GB.
