As for the time it takes for a RCLSTG.  I ran one this weekend on a 4-way
320 with 75+/- Gig about 50 % and it ONLY took
1 hour.  I was pleasantly supprised. I have heard that this system had a
history of disk failures.  Of cource your mileage may vary.

Who, ME??

One of the biggest problems we had with running a RCLSTG is that NO ONE can
estimate how long it will take.  I think the last time we ran one may have
been back on the S/38...
Back then it took the better part of a weekend, time we can't afford to
keep the users away from the system.
Now, of course, we are working towards a MIMIX solution that will allow us
to bump the users off of the system for part of a weekend to allow us to do
RCLSTG and install cume tapes and all sorts of maintenance functions that
we just don't have the time to do without impacting the production
schedule.
Yes, I know, these things have to be done.  And we do our cume tapes at
least quarterly (and strays as we find 'em).  But with the possibility of a
RCLSTG taking a day or more, we couldn't take the risk that the machine
wouldn't be back up on Monday (let alone Saturday night).
With that spectre hanging over our heads, and with our operations group
being fanatical about checking our backups for damaged objects, we judged
that we wouldn't have any problems with damaged objects.
