redhat with HP tape

[kemo]

Hello

I have a problem with HP MSL2024 Library with redhat Enterprise 4, ,kernel: Linux version 2.6.9-78.0.17.ELsmp
tape is giving the below kernel errors on the system's messeges
--------------------------------------------------------------------------
kernel: st0: Error 70000 (sugg. bt 0x0, driver bt 0x0, host bt 0x7).
kernel: st0: Error with sense data: Info fld=0x10000, Deferred st0: sense key Medium Error
kernel: Additional sense: Write error
kernel: st0: Error with sense data: Info fld=0xf4240, Current st0: sense key Medium Error
kernel: st0: Error 70000 (sugg. bt 0x0, driver bt 0x0, host bt 0x7).
--------------------------------------------------------------------------
tape stops working unless you reboot the server, this happens 3 times in a week.
any clue?

Quick look, it says, medium error. Is this medium is new or old ? Have you tried to use new medium ? How many tape drives connected ?
