If One-to-One Connections Link HBAs and Ports
Figure 6-1 shows an example of a network in which each host bus adapter is
connected to only one port on the storage system (Henceforth, this network is
referred to as
network A
). Host bus adapters and the storage system ports are
directly connected and are not connected via hubs and switches.

Network A (One-to-one Connections between HBAs and
Ports)
If one-to-one connections are established between HBAs and ports, take the
following major steps:
1.
Set priority to ports on the storage system using the
Port
tab of the
Server Priority Manager
window.
In
network A
, the ports 1A and 1C are connected to high-priority
production servers. The port 2A is connected to a low-priority development
server. Therefore, the ports 1A and 1C should be given high priority, and
the port 2A should be given low priority.
Figure 6-2 shows a portion of the
Server Priority Manager
window where
the abbreviation
Prio.
indicates that the associated port is given high
priority, and the abbreviation
Non-Prio.
indicates that the port is given low
priority.
Note:
Throughout this manual, the term
prioritized port
is used to refer to
a high-priority port. The term
non-prioritized port
is used to refer to a low-
priority port.
