[Notes]
(1) The new parameter settings is needed to be activated after executing the utility software.
The procedure depends on OS type and parameters.
[Windows] The system is needed to be rebooted after some parameter values is modified,
in order to activate the new settings.
[Linux]
-
The system has to be rebooted when Connection Type(ct)，Port Speed(sp) and
Login Delay Time(lo) are changed.
-
The RAMDISK image is needed to update and rebooting the system if parameters
except Connection Type(ct)，Port Speed(sp) and Login Delay Time(lo) are
changed.
-
If the driver and utilities support Dynamic Parameter Activation feature and this
feature supports the changed parameters, the parameters are can be activated
temporarily without reboot. However, to use the newly configured parameter
continuously after reboot, the RAMDISK image has to be updated to change this
parameter permanently.
-
If the specified parameter value or the activated parameter value is needed to
check, refer to the section "Display or Set the Port Information" for details.
(2) If both types of parameters, general to all ports and port-specific one, are stored in the
/etc/hfcldd.conf in Linux or the registry in Windows, the driver uses port-specific parameter
value. Parameter values general to all ports are configured when the command-line
parameter '-p all' is specified to hfcmgr command, or the entries is changed in the menu
"Set parameters to All Adapters" of hfcddutil commands.
(3) When parameter values of "Connection Type (ct)", "Port Speed (sp)" or "Login Delay Time
(lo)" are changed, these values are stored in the FLASH-ROM on the Adapter. Therefore,
do not close the working window, terminate the command forcibly, turn the power off or
reboot the system. Such operations might damage FLASH-ROM and may lead the failure
of the Hitachi Gigabit Fibre Channel Adapter.
(4)
If the adapter port is used as shared FC, the following settings have to be applied.
①
If the port is connected to the FC switch, set Connection Type 'Point to Point'.
②
If the port is connected to the disk device directly, set Connection Type 'FC-AL'.
(5) If the FC extension card is mounted on Hitachi Compute Blade 320, the parameter value
'auto' should not be set to the Link Speed parameter and a fixed value has to be set. Refer
to 'Hitachi Compute Blade 320 User's Guide' - 'FC HBA BIOS' for details.
(6) Notes on setting interrupt type. [Linux]
Depending on the system configuration, the driver may fails to activate the specified MSI-X
interrupt type and reports Error Number 0xB0 to the OS log.
If Interrupt Type is changed, then after updating RAMDISK image and rebooting the system,
be sure to check the activated parameter value. 2Gbps and 4Gbps Fibre Channel Adapters
cannot work with MSI or MSI-X interrupt type. If both 4Gbs Fibre Channel Adapter and
8Gbps Fibre Channel Adapter are used on a system and MSI-X interrupt type is specified
for all adapters, the error code 0xB0 is reported for the 4Gbps Fibre Channel Adapter since
MSI-X interrupt type is not supported on the 4Gbps Adapter.
(7) Supported parameters and its range are different depending on the type of Hitachi Gigabit
Fibre Channel Adapter. Refer to the following table below. Please refer to 'HITACHI Gigabit
Fibre Channel Adapter USER'S GUIDE (Support Matrix Edition) for Correspondence
between Hitachi Gigabit Fibre Channel Adapter's model name and its product ID.
