The basic core syntax for adding or deleting I/O resources is:
-a|d io:hardware_path
where:
add
delete
the hardware path of the I/O
To add all hardware using the SBA/LBA hardware path of 1/2 to an existing partition winona2:
winona1# vparmodify -p winona2 -a io:1.2
To remove all hardware with SBA/LBA 1/2 from partition winona2:
winona1# vparmodify -p winona2 -d io:1.2
