Hi,

Extracting files from tape
After the system recovery tape has been created, a single file or
files can be extracted from tape by seeking to the tape position where
the archive is located. The mt command can be used to seek to the
appropriate location, and pax or tar can be used to extract files from
the archive.

To extract a single file from the recovery archive:

mt -t /dev/rmt/0mn fsf 1
tar -xvf /dev/rmt/0m filename

Extracting files from tape can take a long time, especially when
archives are large.

check out man make_recovery

Hope this will help,

Gideon

Hello,
Insert your ignite tape
when the server boots interrupt at startup.
Use
main menu>sea
to search for bootable devices
check the path for the tape drive

main menu>boot

Then
# mt -t /dev/rmt/0mn fsf 1

no-rewind option with the 'mt' command to skip over the LIF written on the tape by Ignite

# tar -xvf /dev/rmt/0m
use 'tvf' to list the contents of the tape.

Thanks

Hi

This should workto extract a single file from the recovery archive:

# mt -t /dev/rmt/0mn fsf 1 # this moves forward

# tar -xvf /dev/rmt/0m filename # use the regular tar command


To be sure as this is theoretical use
tar -tvf first to see if the tape reads and then repeat to extract the file.

Remember
Extracting from tape can take a long time, when
archives are large.

mt -t /dev/rmt/0mn fsf 1
tar xvf /dev/rmt/0m your_filename

Note: for /dev/rmt/0mn, you must use "n" option.

Hi,

Off course all answers are correct.

Just one remark !

It is not needed to boot from the tape as TG mentioned.

Just skip the first part of the tape with the mt command and then use tar to restore the file from the tape.
