The unsupported 'SHow LIBrary' command is useful in revealing what ADSM
thinks of the status of your library and drives.  We had a situation a week
ago wherein one of our 3590s died on a DC power supply failure.  This showed
up in the AIX error log ('errpt'), and 'SHow LIBrary' revealed that ADSM knew
about it - even when AIX and other ADSM commands knew not of the problem.
(Additionally, the 3494 still thought the drive Available.)  I might mention
that the 3590 errors flooded the AIX error log until I rendered the drive
Unavailable at the 3494 console, whereupon they instantly stopped; so that's
a way to end them.            Richard Sims, BU
