HP-Unix B:11 #32 bits - Write Failed : I/O Error ....

[Bokoko]

Hi Stephen,

Thanks for oyur prompt reply.

Unfortunately, I've cleaned and changed a new Tape. The Backup is not running as I hope. Is there any conflict between the Device and the current driver? How can I know or check this conflict. Before calling the HP suport, is there any problem with the connection?

Many thanks,

Engo.

If youve got a hardware problem it will show up in dmesg. Run /usr/sbin/dmesg and see if it lists any errors at the end of its output. If it is hardware you will have to call HP.

I doubt its a driver problem - unless youre using a non HP supported tape drive. Normally HP DDS drives look like this (DDS first then DLT);

ioscan -fknCtape

Do yours look like this ?

Hi there,

after running "ioscan" and "dmesg", this is what I've found :

cyb_hpux [ / ] # ioscan -fknCtape

I think, it is fine but what about the Message Error.

I recommend you contact your local HP support office to assist you with this issue.

Hi:
I am experiencing the same problem, only on a DLT8000 drive. I have changed tapes and am running a new backup and mine seems to be running fine now. I had the same errors you had, I would try a couple different tapes, to rule out a tape problem... If it keeps stopping, does it stop on the same file everytime? If so, it might be a file or block problem on that disk??

[Stefan Farrelly]

Yeah, I/O error during close is either tape or else the drive is on its way to the bin and you will need to call HP to replace.

[Jon Finley]

Or.. it's time to break out the cleaning tape.
