lldpad: FCoE Application TLV fails to become active during install
Last modified: 2012-05-24 06:06:15 EDT
Description of problem:
The anaconda script for fcoe will start lldpad and then invoke a couple dcbtool commands to enable DCB and enable the FCoE application TLV for the selected interface.
The dcbtool commands may fail depending on timing of the commands and whether or not the link is up or down. If the application TLV is not enabled, the results can be indeterminate. Sometimes the installation may complete fine, in other cases, an important feature like priority flow control (PFC) may not be enabled by the switch and the resultant FCoE traffic needed for installation is not able to complete due to too many dropped packets.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. begin the installation process and take the options to install to
special devices. search for FCoE targets/LUNs.
2. once the FCoE target search is completed, switch to a command line console
query the state of the FCoE application TLV. Ex. dcbtool gc eth0 app:fcoe
The dcbtool query will show that the FCoE Application TLV is not enabled.
(can also check for the 'dcbtool' commands in /tmp/program.log file and check
for the results of the commands to see if they succeeded or failed)
The FCoE Application TLV should be enabled.
