A Storage driver-level parameters Examples Following is an example to set the LUN queue depth. esxcfg-module -s 'lun_queue_depth=1' bfa Following is an example to disable FDMI. esxcfg-module -s 'fdmi_enable=0 bfa' bfa Important notes Observe these notes when modifying driver configuration parameters: • The esxcfg-module reads and updates from the file /etc/vmware/esx.conf. • Editing this file directly is not recommended. • Be careful not to overwrite the existing options. Always query the existing configuration parameter value before changing it using the following command: esxcfg-module -q Windows driver configuration parameters The BFA driver configuration parameters are located under the registry hive: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\bfad\Parameters\Device Table 35 describes the Windows configuration parameters. TABLE 35 Windows driver configuration parameters Parameter Default Value Notes fdmi_enable 1 bfa_lun_queue_depth 32 ioc_auto_recover 1 rport_del_timeout 90 msix_disable 1 Enables or disables Fabric Device Management Interface (FDMI) registrations. To disable, set this parameter to 0. Maximum SCSI requests per LUN. This parameter is passed to the SCSI layer during SCSI transport attach Auto recoveries IOC (IO Controller) on heartbeat failure. Delay in seconds, after which an offline remote port will be deleted. Disable MSIx interrupt (and use line-based INTx). Managing Windows driver configuration parameters To change any driver configuration parameter, use the Registry Edit tool (regedt32) or the BCU drvconf --key command. For details on using these commands, refer to the Brocade Adapters Administrator's Guide. Important notes: • We recommend using the applicable BCU command to dynamically update the value (where available), rather than reloading the driver. • Disabling the devices will disrupt adapter connectivity. • To find out if the driver has unloaded successfully after disabling the Brocade HBA or CNA devices in the Device Manager, run any BCU command. This should result in an "Error: No Brocade HBA Found" or "Error: No Brocade CNA Found" message. If the driver did not unload for some reason, the BCU command should complete normally. 208 Brocade Adapters Installation and Reference Manual 53-1002144-01
