Figure 8-8. Identifying the SCSI Host ID
Figure 8-8 shows 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
.
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
