You must apply High Speed mode or Initiator/External MIX mode to groups of four ports, not to
individual ports. In LUN Manager terminology, each group of four ports is referred to as a port
block. You can apply High Speed mode or Initiator/External MIX mode to each port block.
When you apply High Speed mode or Initiator/External MIX mode, each pair of ports in a port
block must satisfy the following conditions.
•
The two ports take the same fabric option (Enable or Disable).
•
The two ports take FC-AL as the Connection option.
•
The two ports use different port addresses and no matching addresses.
•
When you apply High Speed mode, the two ports take the same port attribute (the attribute
can be Initiator, RCU target, or Target).
•
When you apply Initiator/External MIX mode, one port takes the Initiator attribute and the
other port takes the External attribute.
•
Only one port is to be used for connecting the host.
“Ports in High Speed Mode or Initiator/External MIX mode” (page 69) shows an example of High
Speed mode or Initiator/External MIX mode applied to one or two port blocks when the channel
adapter board has 8 ports.
