make_tape_recovery -Avl -a /dev/rmt/0mn -x inc_entire=vg=00
...
WARNING: The volume group /dev/vg00 will be only partially included in the System Recovery Archive. 

The command line option has a spelling error: inc_entire=vg=00 should be inc_entire=vg00

Also, the -l option is used to specify the LAN MAC address so it will create an error message at the beginning.

The recommended command line would be:

make_tape_recovery -I -A -v -x inc_entire=vg00 -a /dev/rmt/0mn

Note the -I option is an uppercase letter i.

But more important:

errno=5 means that the data could not be read. This is a hardware failure. Your vg00 disk has gone bad and must be replaced. You should be seeing lots of error messages in syslog and also dmesg.
