3582 Firmware

[rob@xxxxxxxxx]

I recently upgraded the firmware on my 3582-L23 to
  Application  307B.GY001 
  Picker       004.0B2 
  RMU          190C 
  Drive1       53Y2 
  Drive2       53Y2 
  Boot         105A.00005 
  Picker Boot  BOOT.3F 
Since doing so I am getting the following error in my backup program
VRYCFG CFGOBJ(TAP04) CFGTYPE(*DEV) STATUS('*ON')
CPD2616-Device TAP04 vary failed. No recovery attempted.
Reason code is 00003404.  00003404: An error occurred during vary on 
processing.
Recovery  . . . :00003404: Check your hardware to ensure it is connected 
correctly and is powered on.  Look for any tape VLIC logs (major code 
2E00) or error logs that were created around the time of failure which may 
indicate the problem.  Then try the request again. 

Nothing in WRKPRB.
Nothing in the Product Activity Log.
Nothing in the Service Action Log.

Backup does a second vary on in the code and it works.

Varying on from the command line works the first time.

Programs have not been modified in months.

Tape drive is shared via a 2109-F16 fiber switch between 3 different 
boxes.  All three boxes use the 5704 fiber card, supported by a 2844 card. 
 Since the firmware upgrade they are all getting the errors.  There is a 
large time lag between one machine finishing it's backup and varying the 
tape drive off and before the next machine varies it on.  That rather 
rules out that conflict.  That, and the fact that it would be pretty 
freaking amazing for the second vary on to always work when it's only 
seconds away from the first.  Also, the error message from the first 
varyon occurs subsecond - no wait time involved.

Tried opening up a software problem but the lazy buggers there give me the 
old "We are not allowed to debug cl pgms."
