Library Manager, microcode level        Obtain at the 3494 control panel:
                                        First: In the Mode menu, activate the
                                        Service Menu (will result in a second
                                        row of selections appearing in menu bar
                                        at top of screen).
                                        Then: under Service, select

                                        "LM Patch Level", which will show a
                                        number like "512.09".

>Can anybody explain what the device category of A6A0 means?

That's a mystery - I've never seen that before.  It's within the defined
range of "General programming use", though.  When the Library Manager microcode
was updated, was any peculiar inventory function started (and perhaps
canceled)?  Were the six tapes with this odd category code together in one
frame wall of the 3494 (suggesting odd inventorying)?

You may want to have your CE search the hardware database for this code,
as it may be indexed as relating to some odd condition with this microcode
level.
