Re: DASD capacity & fiber cables

Say what???

The only way that's possible is if the BP configured a huge number of 
tiny LUNs and used up all the LUN count on the existing ports. Thing is 
that's a LOT (like 128 per port!)

Normally what you would  need to do is create additional LUNs on the 
SAN, assign them to the existing host for the IBM i partition and then 
add them to the ASP (with balance of course) in service tools.

We saw a jump in disk performance, but for some reason IBMi didn't show an increase in overall DASD.  Our business partner said that we need to add additional fiber cables between the server and the SAN to see the additional capacity.  That seems like a simple enough thing to do, but I'm trying to wrap my head around how that works.  Can anyone explain why more fiber cables are required in order to have the increased disk capacity?
