cpio error

Fernando Jose P de Souz — Tue, 06 Jul 2004 08:24:15 GMT

I have two servers with hp-ux 11.11 (one have a ultrium and the other don't have a tape).

when i make a backup by remote shell using cpio:
# find . -print | cpio -ovdumBc | remsh HP02PR "cat > /dev/rmt/0mn"
obs.: the server without tape for server with tape

The backup is ok, but when i list, appears the following message:
out of phase
and request to use an option R

When i restore a file, appears the following message:
errno:25 , can't read input

Wait.
Fernando.

Try this:

ON HP01PR:

mknod /tmp/somepipename p
echo "+ +" >.rhosts
find . -print | cpio -ovdumBc > /tmp/somepipename

ON HP02PR

remsh HP01PR -l root dd if=/tmp/somepipename | dd of=/dev/rmt/0mn

live free or die

Don't work.

According to /usr/include/sys/errno.h, error 25 means "not a typewriter", which suggests it's looking for input from the keyboard rather than a tape drive.

What command are you using to restore?

When i list the tape.
#cpio -iBtcR < /dev/rmt/0m

View the output in atach.

You're doing the backup by remsh, but it doesn't look like you're doing the restore by remsh. Is that right?

I normally get "out of phase" when I backup with the "B" option. Try removing it.

If that doesn't work, try removing the "c" option, and keeping the B.

cpio -ovdumc
cpio -ovdumB

If it still doesn't work, I'll start guessing....

The "v" option gives you lots of text on the screen. But you're running this with remsh? Maybe that's the problem?

Hope one of these is it.

Try a new tape to see if you get the same error. It could be a bad tape:

when i make a backup by remote shell using cpio is ok, and when i list or recover by remote shell, it's ok too.

Commands:
backup:
# find . -print | cpio -ocvBdxum | remsh mastermm "cat > /dev/rmt/0m"
restore:
# remsh mastermm "cat < /dev/rmt/0m" | cpio -icvBdxum

obs.: But, When i list or restore in other server, give me an error: "out of phase" and use the -R option

Presume my system crash and i would like to restore in other server. what should i do?

Wait.

The problem appears to be your "B" option which specifies 5k blocks.

Instead of:
remsh mastermm "cat < /dev/rmt/0m" | cpio -icvBdxum
Try:

# remsh mastermm "dd if=/dev/rmt/0m bs=5k" | cpio -icvBdxum

You will probably get better performance by larger input blocking:
# remsh mastermm "dd if=/dev/rmt/0m ibs=60k obs=5k" | cpio -icvBdxum
