[Notes]
(1) If the parameter values was changed using the utility software, the new parameter value
should be activated to the Adapter. The procedures are different depending on the OS type
and the changed parameters.
If the parameters which do not support dynamic parameter activation is changed, then the
OS should be rebooted. As for the parameters that support dynamic parameter activation,
the OS is not needed to reboot.
If Linux is used and the parameters stored in /etc/hfcldd.conf is changed, then the
RAMDISK image should be updated. For details, refer to the section "Updating RAMDISK
Image [Linux only]". If the OS is rebooted without updating the RAMDISK image, the OS do
not activate the changed parameters after the reboot. If Windows is used or the parameters
stored in /etc/hfcldd.conf are not changed, the RAMDISK image does not needed to be
updated.
If the specified parameter value or the activated parameter value are needed, 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' to hfcmgr command is specified, or the entries in the menu "Set
parameters to All Adapters" of hfcddutil commands is changed.
As for the parameters stored in FLASH-ROM, the values finally stored in the FLASH-ROM
is used.
(3) When the parameters stored in FLASH-ROM is changed, 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 a malfunction 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.
