1. use tctl command to position mksysb tape at the beginning of fourth
image.

2. use following example from AIX Infocenter:
-----------------------------
# To restore a specific file, type:

restore -xvqf myhome.bkup system.data

This command extracts the file system.data into the current directory
from the archive myhome.bkup. The archive in this example is in the
current directory. File and directory names must be specified as they
are displayed when using the -T flag. The -v flag displays additional
information during the extraction. This example applies to both
file-name and file-system archives.
-----------------------------

Of course, substitute myhome.bkup with /dev/rmt0 (or similiar, if you
have multiple such devices configured).

/usr/bin/restorevgfiles -f /dev/rmt0 -d /particular/location ./var/adm/messages

assuming the image is on rmt0.
