Having a problem reading from a 4mm tape?


Question:

Customer is on AIX Version 3.2.3e.  They have a 7206-001 tape drive and have 
PTF U404963 installed.  Customer says that she is using tapes between her 
system and an HP MPE minicomputer. If she uses brand new tapes on her machine,
they work fine. She can write to and read from them without any problem.
If the same new tapes are used first on the HP MPE system, they are no longer
usable on the RS6000 system.  The exact text of the error is:

 "/dev/rmt0.1: the input or output media is write protected"

Response:

The IBM drive can NOT read the HS-4/90 tapes.  If there is NOT 4 WHITE STRIPS 
near the front of tape on the TOP, the drive will produce the errors above. 
They need to use tapes like the HS-4/90S to have them work correctly.
