frecover is wroking from sam but not from the command line

[Ali Kouider]

Hi

I am trying to read a DDS tape without restoring.
I am using the command frecover -Nxv
it gives me the following error message

hptest:/>> frecover -Nxv -f /dev/rmt/0m
frecover(5419): checksum on volume header is incorrect.
frecover(5420): not an fbackup volume; magic value is incorrect
frecover(5412): Do you wish to try to salvage this volume? (^[yY]/^[nN])

The same tape I can read through SAM and restore also through SAM.

Please advise

Hi

Have a look at the output in /var/sam/log/samlog to see what command sam is running when it is reading your tape

Have you attempted to use frecover with -I option to create an index file. Index file contains the list of all files backed up by fbackup in that archive.

frecover -I /tmp/index -f /dev/rmt/0m

more /tmp/index

I've gotten that error with bad media. The problem with that is if the media is bad its going to fail commmand line or interactive. Trying another tape does seem in order however.

Could this be a patch problem and may be this patch could resolve.
