Query on using CPIO

Harinath N — Wed, 26 Dec 2001 08:26:09 GMT

Hi,

I need to know the command for going through or to list (without writing onto the disk) the contents of the data backed up in a DLT media using CPIO.

Could someone help me on this?

Thanks and Regards,
N.Harinath.

Hi,

Use the -t (listing) option.

if your device is /dev/rmt/2m, then execute:

# cpio -itv < /dev/rmt/2m

Hope this helps. Regards.

Hi,

Thanks for your reply.
I tried with it, but its giving the following output,

"Out of Phase - get help
Perhaps -c option shouldn't be used"

Please help me out on this.

Hi,

It depends on the options you used during the cpio output mode to tape.

Since it is a tape device, use the block device -B option. Thus to list,

# cpio -itvB < /dev/rmt/2m

If -c was used in the output mode, then similarly the -c option must be used in the input mode. Thus to list,

# cpio -ictvB < /dev/rmt/2m

Remember to replace /dev/rmt/2m with the appropriate device file of your DLT tape drive.

Hope this helps. Regards.

Hello,

looks like your tape was NOT the first to be written during that backup - you'll have to start with "cpio -ictv < /dev/rmt/0m" on the first tape, wait until it has been completly read, then you'll get the messaeg to exchange the tape and enter the name of the device containing the follow-up tape, and then you re-do the whole procedure until you used the tape you are interested in...

HTH,
