Title:
ledmon does not work in Ubuntu 14.04
Status in The Dell PowerEdge project:
In Progress
Status in “ledmon” package in Ubuntu:
Fix Released
Bug description:
ledmon will not work in Ubuntu 14.04, due to a change in kernel 3.13.
I've tested this with ICH10R and C600/X79 chipset.
Symptoms: ledctl gives 'enclosure management not supported' on
supported hardware.
This problem has just been fixed by upstream, see this patch:
http://sourceforge.net/p/ledmon/code/ci/6f7d38bbe5d7b13c84987cf3b3b550a11c39392e/
Please update the Ubuntu package to include this patch, so ledmon
works again.
Installed package: ledmon 0.79-0.2
~$ lsb_release -rd
Description: Ubuntu 14.04 LTS
Release: 14.04
[Impact]
* The type of libahci parameter ahci_em_messages was changed from int to
bool in kernel v3.13, which caused AHCI HBAs to not be detected
properly.
* This basically means that ledmon no longer works in 14.04
[Test Case]
* install ledmon and start up the openipmi service
* The following ledctl commands should no longer give 'enclosure
management not supported' on supported hardware with the fix in place:
sudo ledctl locate=/dev/nvme0n1
sudo ledctl locate=/dev/rssda
sudo ledctl locate_off=/dev/rssda
sudo ledctl locate_off=/dev/nvme0n1
[Regression Potential]
* Low, as this bug affects 14.04 and higher due to the newer kernel
version. Systems running the older kernel releases should be fine.
