EMC Host Connectivity with Emulex FC HBAs and FCoE CNAs for the Linux Environment

Installing and Configuring the Linux Host with the Emulex Driver

◆ Start the Emulex Application daemons:

cd /usr/sbin/hbanyware

./start_elxdiscovery

./start_myserver

Note: While loading the Emulex driver using modprobe, it is possible to

specify driver parameters. However, any parameters set in the

/etc/modprobe.conf or /etc/modprobe.conf.local files will

override the values specified on the command line.

Target information exported to the /proc filesystem

The Emulex driver populates the

/proc/lpfc/<host_adapter_number> file with the WWPN and the

WWNN of all targets for each adapter in the system. The

host_adapter_number> increments every time the driver is

unloaded and reloaded.

For example:

cat /proc/scsi/lpfc/1

lpfc1t00 DID 491b00 WWPN 50:06:01:60:10:60:12:70 WWNN 50:06:01:60:90:60:12:70

lpfc1t01 DID 481b00 WWPN 50:06:01:68:10:60:12:70 WWNN 50:06:01:60:90:60:12:70

Dynamically modifying the driver and device information exported to the

/sys filesystem

The Emulex driver exports the driver versions, parameters, and

device information in

/sys/class/scsi_host/ directory. A new

directory is dynamically created for each Emulex

scsi_host_adapter

in the system. Similar to the incrementing of the

host_adapter_number> in the /proc filesystem, the directory

number will be incremented every time the driver is unloaded and

reloaded.

The following is a listing of the directory contents:

cd /sys/class/scsi_host/host1

. events lpfc_lun_queue_depth outfcpio

.. fabric_name lpfc_max_luns port_name

board_online fwrev lpfc_nodev_tmo port_type

cmd_per_lun hdw lpfc_scan_down portfcid

ctlreg host_busy lpfc_topology portnum

device info lpfc_use_adisc proc_name
