Figure 8-8. Identifying the SCSI Host ID

Figure 8-8shows that the QLogic 8100 Series Adapter FCoE function at PCI device ID 85:00.2 maps to host6. QLogic driver parameters can now be configured using /sys/class/scsi_host/host6 and /sys/class/fc_host/host6.

NOTE:

Rebooting the server or reloading the QLogic FCoE driver (qla2xxx) may change the value of the SCSI host ID.

Displaying and Modifying sysfs Entries

To display sysfs entries, use the Linux Cat command. For example, to display the adapter firmware version, issue the following command:

#cat /sys/class/scsi_host/host6/fw_version

To modify sysfs entries, use the Linux Echo command. For example, to enable the beacon on the adapter port, issue the following command:

#echo 1 > /sys/class/scsi_host/host6/beacon
