Can't use Tape using pmt

[lela810]

As you can see, I can use < mt > to manage my tape.
Sadly, using < pmt > like PBS, it doesn't work.

I've tried:
-Different Tapes
-Cleaning Tapes
-LTO-4 Tape
-PBS Upgrade

None of the above helped.

Below I've attached you a print out of the error and some general device info.
Hope it helps

Thank you so much in advance!

does using the tape (drive) work for regular PBS purposes?

 

[lela810]

Sadly it doesn't.
I can't add any tapes to a Media-Pool.

 

[fabian]

could you also post the output of pmt cartridge-memory? thanks!

 

[lela810]

Ofcourse

[fabian]

thanks! I guess we'll require some more debug output to figure out what's going wrong.. @dcsapak @dietmar

 

[dcsapak]

ok, could you post the output of

pmt status
sg_raw -r 1k /dev/tape/by-id/scsi-HUJ52949NU-sg 01 00 00 00 00 00

?

on rewind we literally only issue the scsi REWIND (01h) command, i don't see how what could go wrong there...

 

[lela810]

Sure thing

mhmm ok so the raw 'REWIND' command fails already... strange that the mt command works then..

could you check if there is a firmware update for your drive? we encountered some cases in the past where updating the drive firmware fixed most issues...

 

[lela810]

Sadly I dont have access to the newer Firmware Files from HP

 

[dcsapak]

this is a very basic command and the error message does not really help with finding out whats wrong (the message is most definitely not 'invalid')
so aside from checking the hardware (controller/cable/drive) for errors and updating the firmware there really isn't much we can do here...

 

[Neobin]

Completely wild guess, but what type of controller do you use?
If it is not already an HBA in IT-mode, you could flash it if possible (hardware-side and your environment-side) or try with another pure HBA in IT-mode.
