Affected Product:  See more info
Whitethorne AOM(all modules)

Known Affected Versions:
11.4.0, 11.4.1

Opened: Apr 07, 2014
Severity: 2-Critical


On BIG-IP 5000/7000 Series platforms with AOM (LOP/LBH) firmware version 3.05 or later installed, removal or insertion of a power supply (PSU) does not result in the correct status being updated/shown by the 'tmsh show sys hardware' or 'system_check -d' commands.


The system does not determine correct PSU status after removal or insertion.


BIG-IP 5000-/7000-series appliances running BIG-IP software versions prior to 11.5.0, with LOP/LBH firmware version 3.05 or later installed.


On BIG-IP v11.4.1, it may be possible to accurately refresh the PSU state by restarting the lopd and chmand daemons using the command: bigstart restart lopd chmand. On earlier versions of BIG-IP, a full system reboot or hard power-cycle may be required to accurately reflect the changed PSU state.
