HP XP Array Manager Software - Manual (Page 66)

• If you select the Fibre folder, the Port list displays a list of Fibre Channel ports in the storage
system.
• If you select a channel adapter, the Port list displays a list of Fibre Channel ports on the
channel adapter.
3. Select a port from the Port list or the Select a Port drop-down list.
The Mode area displays information about the selected ports.
4. If a fabric switch is used, select Enable from the Fabric drop-down list in the Mode area.
If a fabric switch is not used, select Disable from the Fabric drop-down list in the Mode area.
5. Select FC-AL or P-to P from the Connection drop-down list.
Note: If a fabric switch is used, consult the documentation for the fabric switch to check if your
fabric switch requires the point-to-point topology. Some fabric switches require the point-to-point
topology to get the system running. To specify point-to-point topology, select P-to-P.
6. Click the Set button.
A message appears and asks if you want to change the port settings.
7. Click the OK button to close the message.
The settings are applied to the Port list (but not to the storage system). The changes are indicated
in blue.
8. Click the Apply button.
A message appears and asks if you want to apply the setting to the storage system.
9. Click the OK button to close the message.
The settings are applied to the storage system.
Warning : When you change the settings while you are online to the hosts, the device may not be
recognized from the hosts. In this case, you will need to reboot the hosts.
Changing the Fiber PCB Mode Between Standard, High Speed, and
Initiator/External Mix Mode
Channel adapter boards have built-in ports to be used for connecting hosts and a storage system. The
ports can be in Standard mode, High Speed mode, or Initiator/External MIX mode, though all the ports
are in Standard mode by default. If a port satisfies certain conditions, you can apply High Speed
mode to the port to improve port performance. Or, if a port satisfies certain conditions, you can apply
Initiator/External MIX mode so that one port can be used as both an initiator port for Continuous Access
or HP StorageWorks XP Continuous Access Journal Software and an external port applied to a remote
command device. For more information on how to define the remote command device, see the HP
StorageWorks XP24000 External Storage Software User’s Guide.
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.
Figure 38 on page 67 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.
