When sharing 20 LUNs by 6 Linux operating systems you just need to have a
single subchannel on each of the FCP channels you are using as mentioned by
Steffen.
Since you are running in NPIV mode you just must apply the correct LUN
masking in your Storage servers for the WWPNs that are used by the guests.

So you should just have 4 WWPNs for each Linux instead of 80.
