Interrupt Type
(-p ir) [Linux only]
This parameter specifies interrupt mode. The parameter is set to the optimum value for a general purpose,
so usually this parameter does not need to be changed.
In Windows, this parameter can be set in Windows Server 2016. In Windows Server 2008 R2 or lower
Windows version, the driver runs with INT, and in Windows Server 2012 and Windows Server 2012 R2, the
driver runs with MSI-X.
Refer to the table below for the descriptions of the diplayed values.

<Notice: when logical device name is used>
In Linux, if 2G/4G/8G Fibre Channel Adapters is used and a logical device name is specified, all ports on
the Fibre Channel Adapter that contains the logical device is set to use the specified value. If 16G Fibre
Channel Adapter is used, only specified device is set to use the specified value.
Logging Mode
(-p lm)
If FC-Switch is used and its ports are not separated into zones, for example, Access Gateway mode of the
FC-switch is used, the adapter ports access each other. Because of this reason, Link Down of the other
adapter port or the server reboot may make the driver log unnecessary errors, such as the followings;
0x18 (RSCN is received)
0x0e (Login is failed)
0x16 (PLOGI is received)
0x17(LOGO is received)
If this option is disabled, the driver does not log when accessing the other port. However, this option makes
the driver not to collect any 0x0e (Login failed) log, for example, due to incorrect Zoning in FC-Switch or
false LUN security setting. Please read Access Gateway mode in the manual of the FC-Switch.
If "verbose" is set to this parameter on a 16G Adapters, the driver rejects unsupported FC protocol frames or
supported FC protocol frames with some errors and logs errors as 0xDC. If 16G adapter is not used, the
driver recognizes this parameter as a default.
