Configuring the Interrupt Control Coalesce using the GUI (HBA only)
1. Select a port from the device tree.
•
From the Host Connectivity Manager, select Configure > Advanced Port Configuration.
The Advanced Port Configuration dialog box displays.
OR
•
Right-click a port and select Port Configuration > Advanced.
2. Set the latency and delay values:
•
Select On from the Interrupt Control Coalesce list.
•
Specify the latency monitor timeout value in microseconds, if coalesce is set to on. Latency
timeout values supported are 0-225 microseconds. Setting the latency timeout value to 0
disables the latency monitor time out interrupt.
•
Specify the delay timeout value in microseconds, if coalesce is set to on. Delay timeout
values supported are 0-1125 microseconds. Setting the delay timeout value to 0 disables
the latency monitor time out interrupt.
3. Click OK.
NPIV
N-Port ID Virtualization (NPIV) enables a single Fibre Channel protocol port to appear as multiple,
distinct ports. NPIV provides separate port identification within the fabric for each operating system
image (partition) behind the port, as if each operating system image had its own unique physical
port.
Each NPIV device has a unique virtual port ID (PID), port WWN, and node WWN. The virtual port has
the same properties as an N_Port and is therefore capable of registering with all services of the
fabric. In other words, multiple virtual devices emulated by NPIV appear no different than regular
devices connected to a non-NPIV port. The maximum number of virtual PIDs for an N_Port on a FC
switch is 255. For a CEE switch, the maximum number of V_Ports is 64.
NPIV is available at the physical port level or at the virtual fabric level. If virtual fabric ports are
detected, then you cannot configure NPIV parameters at the physical port level. If virtual fabric
ports are deleted on the switch port side, the NPIV parameters can then be configured at the
physical port level. No settings are available for V_Ports from basic port configuration.
NOTE
NPIV is not supported on Solaris platforms.
