10-3-4 Configuring Fibre-Channel Adapters (StorageWorks XP1024/XP128
and XP512/XP48)
CAUTION: Before changing the setting of a channel adapter, make sure that the storage subsystem is
equipped with channel adapters capable of high-speed mode, that you are aware of the impact of changing
the setting, and that you understand the procedure for connecting hosts to a channel adapter in high-speed
mode.
The system administrator and the storage administrator can configure fibre-channel adapters on the
StorageWorks XP1024/XP128 Series and StorageWorks XP512/XP48 storage subsystems. Guests, local
system administrators, local storage administrators, and local guests do not have access to this function.
The three types of fibre-channel adapters for the StorageWorks XP1024/XP128 are 4-port, 8-port, and 16-port
adapters. You can set the fibre printed circuit board (PCB) mode only for 4-port fibre channel adapters.
Standard mode is the default channel adapter mode. High-speed mode provides faster access speed by using
more processors to handle data access. However, high-speed mode limits the number of available ports on the
channel adapter card (one port for XP1024/XP128, half of the ports for XP1024/XP128). Servers or switches
attached to these ports must be changed for this configuration. Once the storage subsystem and attached
servers or switches are configured for high-speed mode, you can use Device Manager to change the mode of
the channel adapter.
For more information on the channel adapter settings, refer to the HP StorageWorks LUN Configuration and
Security Manager XP User Guide for the XP1024/XP128.
To configure the speed mode of the fibre-channel adapters in the XP1024/XP128 or XP512/XP48 storage
subsystem:
1. Log in to Device Manager as a system administrator or storage administrator.
2. Select the Subsystems object in the navigation frame, select the desired storage subsystem, and then
select the Physical View button.
3. Select Port Controllers to open the Port Controller panel (see Figure 10-28 ).
