output file /dev/rmt/3m is not a valid device file for backup

[jhay reccion]

Hi All,

All device file in ioscan -fnC tape output backup and restore using tar command works fine. But using fbackup command, the above message appears.
Can some help me identify the problem?
Thanks.
Jhay

[Robert-Jan Goossens]

HPUX version ?

[Fred Ruffet]

Could you post output from "ioscan -fkn -C tape", fbackup and tar ?

Regards,

Fred

[jhay reccion]

It's HPUX 11.11

[Robert-Jan Goossens]

Hi Jhay,

could you check the device file /dev/rmt/3m

# file /dev/rmt/3m
0m: character special (205/12288)

anc could you check your system for this patch. PHKL_29899

# swlist -l | grep PHKL_29899

Best regards,
Robert-Jan

[jhay reccion]

hi Robert,

[/dev/rmt]#file /dev/rmt/3m
/dev/rmt/3m: character special (205/24576)

[/dev/rmt]#swlist -l product |grep PHKL_29899

--> it seems that i'm lacking of this patch

[Robert-Jan Goossens]

Just to check :-)

Is there a tape inside the drive ?

Robert-Jan

[jhay reccion]

Hi Robert-Jan,

Yes, there is. I've used that tape on my tar backup/restore.

[bhavin asokan]

hi,

which tape drive you are using --which is appeared as 3m.pls post a copy of output of ioscan -fn command.

can you move the file to some other name and recreate with insf -e command.


regds,

[Fred Ruffet]

What kind of tapes do you have in your drive ? (LTO, DDS, DLT...)

Regards,

Fred

[jhay reccion]

Hi,
I'm using a DLT tape.
It was strange because it works on tar command but not on fbackup.

PS. I've already installed patch PHKL_29899, but still doesn't work on fbackup.

[Fred Ruffet]

May sound stupid, but : Have you tried to use a cleaning cartridge ?

Regards,

Fred

[Fred Ruffet]

you could also try to rewind tape :
# mt -f /dev/rmt/3m rew
or init tape usinf mediainit (man mediainit) for more info.

Regards,

Fred

[jhay reccion]

Hi Fred,

I did use a cleaning tape.
mt rewind command is successful.
still fbackup won't work.

FYI. I'm using a Digital DLT7000 tape drive (taken from our other server- Tru64 machine)

Thanks, jhay

[John Palmer]

The drive you are trying to use is not supported by fbackup.

Have a look at this previous thread...
http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=629179

One question though... Is this a genuine DEC TZ87 drive or a DLT4000 set to emulate one. If it's a DLT4000, you can change the config switches so that it appears as a DLT4000 and will work with fbackup.

Regards,
John

[jhay reccion]

Hi John,

It is a genuine DEC TZ89 tape drive.
I did try to use the recommendation on the other thread to use hostname in fbackup command, but still, it doesn't work.
Is there any patches available so that i could use non-HP tape drive?

Thanks, jhay

[Fred Ruffet]

And what about mediainit ?

Regards,

Fred

[Gennaro Tarone_2]

Mediainit usually doesn't work with a DLT7000 tape drive will get SCSI_IO_CMD error message. What firmware rev is the tape drive at? Since it was hooked up to a True64 server it may have a different firmware rev that is not compatible with HP-UX. You can use Library Tape & Tools to down load/check tape drive & firmware.

[jhay reccion]

Hi To All,

The tape drive is not supported by the current HPUX box i'm using as per HP support. We manage to replace the tape drive with supported one and my backup works as expected.
Thank you for all your support!

Cheers, jhay
