Why doesn't ipmitool detect my second power supply?
I have 2 powersupplies plugged into my machine, but calling ipmitool sensor only shows PS1:
:~$ sudo ipmitool sensor |grep PS
PS1 Status | 0x1 | discrete | 0x0b00| na | na | na | na | na | na
Unplugging PS1 and rerunning that command gives:
:~$ sudo ipmitool sensor |grep PS
PS1 Status | 0xb | discrete | 0x0b00| na | na | na | na | na | na
So I know that ipmitool is detecting the first powersupply status correctly, and that the second powersupply is actually plugged in and working (because the 0xB implies that PS1 has failed, yet the machine is still running)
I'm seeing this issue on multiple units, these machines are:
- SUPERMICRO X9DRW-7TPF+
- OS: Ubuntu 14.04
- ipmitool: 1.8.13-1ubuntu0.2

Unplug all power cables from power supplies. Insert all power supplies into chassis. Plug the power cables into outlet. Then, IPMI should detect all power supplies.
