cpio on hp-ux 10.20

[OldSchool]

"So the bottom line is you can not setup block size for cpio when restore from the tape drive."

see Dennis' reply above. He notes -B will reset the block size to 5120.

better yet, he suggested (twice) that you use "pax" instead, which will sort out the blocking correctly.

having hit "End of Volume" and continued on using the same tape w/o rewind makes me wonder how the tape was produced in the first place.

So I can pax to restore the file that created via cpio? If so, what's the command?

Can you provide the cpio commands that I can use with -B and dd for getting cpio file from /dev/rmt/0m?

Tks.

Yes: pax -rv -f /dev/rmt/0m

>Can you provide the cpio commands that I can use with -B and dd for getting cpio file from /dev/rmt/0m?

-B works only if you used -B to write it.

Using dd(1) is completely separate more complicated approach.

Hi Tammy:

I would add, for your further information, that 'cpio' cannot archive 'largefiles' (files > 2GB).

With 'pax', when Using '-x cpio' or '-x ustar' files up to 8GB can be archived.

In 11.31 or in 11.23 with the PAX_ENH product installed, 'pax' can archive files larger than 8GB.

HP is making 'pax' a defacto standard for HP-UX and is in fact, deprecated (the extremely useful but proprietary) 'fbackup' utility.

Regards!

Hi (again) Tammy:

Oh, the above is just another reason to move from the unsupported, ancient 10.20 release to at least 11.11.

I keep missing the fact that you noted your release as 10.20.

Regards!

Thanks all. We moved from hp-ux to redhat linux. For this particular case, I need to restore file that was created years ago on hp-ux 10.20 with cpio command to get some oracle data out...
I will try the "pax" command.

Tks.
