Herbie,
That may be another possibility.
However, the clunkers I worked with in the past seemed to require a
different touch. If I had a tape drive go offline/boxed because of a
hardware error in the drive and the drive had to be repaired, quite
frequently a 'vary online' wouldn't work. Don't ask me why, but that's how
it was. We assumed that it was a problem with the RS6000 masquerading as
control unit not properly recognizing that the drive was OK again, not
resetting itself internally and not properly communicating that fact to the
M/F. A reboot of the control unit always helped get everything back to
working again.


Regards,
Ulrich Krueger

Ulrich,

The last time I had a boxed one... on a R14... I took all the tape units
offline, took the chpid offline, Varied the chpid online, varied the
units online, and it was OK. I normally don't go near the hardware
inside the Steel casings... 

Regards

Herbie
