# Script to read EDD information from sysfs and

# echo the FCoE interface name and target info.

# This is a work in progress and will be enhanced

# Usage: sysfs_edd.sh -t for getting FCoE boot target information.
|
|
||||||
# sysfs_edd.sh -i for getting FCoE boot NIC name.
|
|
||||||
# sysfs_edd.sh -m for getting FCoE boot NIC MAC.
|
|
||||||
# sysfs_edd.sh -e for getting FCoE boot EDD information.
|
|
||||||
# sysfs_edd.sh -r for getting FCoE boot EDD interface type and path.
|
|
||||||
# sysfs_edd.sh -a for getting all FCoE boot information.
|
|
||||||
# sysfs_edd.sh -h for usage information.
|
|

# Optional: use -v to turn on verbose mode.

# FCoE Boot Disk is identified by the following format of boot information

# in its corresponding sysfs firmware edd entry, i.e.,
|
|
||||||
# /sys/firmware/edd/int13_dev??/interface

# which is formatted as (for FCoE):
|
|

# string format: FIBRE wwid: 8c1342b8a0001620 lun: 7f00
|
|
||||||
# Please ref. to T13 BIOS Enhanced Disk Drive Specification v3.0 for more

# defails on EDD.
