I have a Windows 2000 server instance providing Networker 7.2.1 master service, 
attached to a Dell136T with LTO1 drives.  However, the last powercycle of the 
Dell came up with only 2 of the 4 drives online.  The other 2 report hard 
errors on the library console/LCD.  Thing is, I can survive just fine on two 
drives....the environment has been shrinking.  But the Wintel + Dell reboot 
also re-ordered the drives, so I can't simply down the 2 broken and leave the 
other 2 online...I have to rebuild the jukebox.

This is where my problem comes in.  JBCONFIG of autodetected SCSI of the 136T 
tries to force me to enter values for elements 254, 255, 256, and 257.  And 
only 256/257 are working devices.  No matter what I try, jbconfig will only 
accept \\.\Tape0 and \\.\Tape1 (discovered)...and I can't repeat them then 
disable either.  But what about the other 2 elements?  Can I create a spoof or 
fake \\.\Tape2 and \\.\Tape3 so that I can put the broken drive elements as the 
spoofed values, and the working drive elements with their proper discovered 
device path?

Any other ideas are welcome....I had not anticipated being forced to enter 4 
different \\.\TapeX values when I only have 2 recognized by the OS.  Thanks.
