It's been a while since I used a CX array, but I understood there were
the number of hosts the array was licensed to support which was a
different number from the number of power-path licences you may have. 
Our array could support 8 hosts but we only had 4 power path licences. 
(Which I never used, the RHEL servers were set-up with
mapper-multipath).

I think you will find your array will simply not allow more hosts than
it's licensed for to connect.
