2. Move the cartridge from slot 1 to the first tape drive.
# mc –p /dev/rac/c9t0d0 –s S1 –d D1
3. Ensure you are in the root directory.
# cd /
4. Back up the HP-UX kernel using tar.
# tar cvf /dev/rmt/1mnb ./stand/vmunix
5. Move the cartridge back to slot 1.
# mc –p /dev/rac/c9t0d0 –s D1 –d S1
Restore the HP-UX kernel (iSCSI and Fibre Channel)
1. Move the cartridge from slot 1 to the first tape drive.
# mc –p /dev/rac/c9t0d0 –s S1 –d D1
2. Create a temporary folder to restore the backup into.
# mkdir temp
# cd /temp
3. Restore the HP-UX kernel to the temporary folder.
# tar xvf /dev/rmt/1mnb
4. Move the cartridge back to slot 1.
# mc –p /dev/rac/c9t0d0 –s D1 –d S1
5. Compare the original HP-UX kernel with the restored HP-UX kernel.
# cmp /stand/vmunix /temp/stand/vmunix
If no differences are found between the two files, no message will be displayed.
