LU paths are removed from the table on the right of the tree. The LUNs corresponding to the
removed LU paths are displayed in blue.
5. Click Apply in the LUN Manager window.
A message appears and asks if you want to apply the changes to the storage system.
6. Click the OK button to close the message.
The changes are applied to the storage system.
Configuring Fibre Channel Ports
You can use the Port window ( Figure 9 on page 26) to configure Fibre Channel ports in your storage
system. You can also use this window to modify the port configuration when the system is in operation.
• Specifying the data transfer speed for Fibre Channel ports (see
“ Setting the Data Transfer Speed for Fibre Channel Ports ” on page 63)
• Addressing Fibre Channel ports (see “ Setting Fibre Channel Port Address ” on page 63)
• Specifying topology (see “ Setting the Fibre Channel Topology ” on page 65)
• Choosing between standard mode and the high speed mode (see Changing the Fiber PCB Mode
Between Standard, High Speed, and Initiator/External Mix Mode on page 66)
Setting the Data Transfer Speed for Fibre Channel Ports
As the system operation continues, you might notice that a larger amount of data is transferred at
some ports but a smaller amount of data is transferred at some other ports. If you set a faster data
transfer speed for ports where a larger amount of data is transferred, you will be able to optimize the
performance of your system. If you set a slower data transfer speed for ports where a smaller amount of
data is transferred, you will also be able to optimize the performance.
To specify the data transfer speed for a Fibre Channel port:
1. Start LUN Manager and display the Port window ( Figure 9 on page 26).
2. In the Package tree, select the Fibre folder or a channel adapter of a Fibre Channel
( Figure 9 on page 26).
• 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. Select the desired data transfer speed from the Host Speed drop-down list in the Mode area.
5. Click the Set button.
A message appears and asks if you want to change the port settings.
6. 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.
7. Click the Apply button.
A message appears and asks if you want to apply the setting to the storage system.
8. Click the OK button to close the message.
The settings are applied to the storage system.
Setting Fibre Channel Port Address
When configuring a system, you need to set addresses for Fibre Channel ports. When addressing
Fibre Channel ports, you can use AL-PA (arbitrated-loop physical address) or loop IDs as the addresses
(for details, see Table 6 on page 64).
Note: For more detailed information about Fibre Channel device addressing, see HP StorageWorks
