Amber light on one of my redundant power supplies suggested
something went wrong. That's what I've found in SEL:
978 | 04/21/2008 | 19:12:03 | Power Supply #0x70 | Failure detected |
Deasserted
98c | 04/21/2008 | 19:12:04 | Power Unit #0x02 | Fully Redundant
9a0 | 04/21/2008 | 19:12:04 | Power Unit #0x02 | Redundancy Lost
9b4 | 04/21/2008 | 19:12:04 | Power Unit #0x02 | Non-Redundant:
Sufficient from Insufficient
Ok.. lets have a look:
[EMAIL PROTECTED] ~]# ipmitool sdr list | grep PS
PS1 AC Current | 0.06 Amps | ok
PS2 AC Current | 0.93 Amps | ok
PS1 +12V Current | 0 Amps | ok
PS2 +12V Current | 15.50 Amps | ok
PS1 +12V Power | 0 Watts | ok
PS2 +12V Power | 184 Watts | ok
PS1 Status | 0x03 | ok
PS2 Status | 0x01 | ok
Hm... OK? Let's look deeper:
[EMAIL PROTECTED] ~]# ipmitool sensor get "PS2 Status"
Locating sensor record...
Sensor ID : PS2 Status (0x71)
Entity ID : 10.2
Sensor Type (Discrete): Power Supply
States Asserted : Power Supply
[Presence detected]
[EMAIL PROTECTED] ~]# ipmitool sensor get "PS1 Status"
Locating sensor record...
Sensor ID : PS1 Status (0x70)
Entity ID : 10.1
Sensor Type (Discrete): Power Supply
States Asserted : Power Supply
[Presence detected]
[Failure detected]
SO, how come sensors report "ok" while it's definitly
NOT OK? Another sensor also misleads:
[EMAIL PROTECTED] ~]# ipmitool sdr list | grep "Power Redundancy"
Power Redundancy | 0x0a | ok
while:
# ipmitool sensor get "Power Redundancy"
Locating sensor record...
Sensor ID : Power Redundancy (0x2)
Entity ID : 21.1
Sensor Type (Discrete): Power Unit
States Asserted : Redundancy State
[Redundancy Lost]
[Non-Redundant: Sufficient from Redundant]
PS. Intel SR1550SASR box with S5000PAL m-b
