fan0 disconnected on L2000

[KCS_1]

Hi,

My server is givming me a message "Fan0 disconnected and reconnected,No Action required" in event.log by EMS as well as syslog.log in feb/16

But system is running as normal condition and slow fan0 speed.

How should I do for this??

Hi,

Sounds to me like the sensor - or even the fan itself - is cycling between good & bad.
Either way it should be a case where an HP CE dhould be summoned so give the Response Center a call & log a case.

Rgds,
Jeff

Should check for the fan0, I think you need to call to HP support and get support form HP. Because, if you want to check must be HP engineer present :):)

Anyway, the fan has redundance!

Hi,

It looks like tempeature sensor problem. The fan management board should be replaced. Could you talk with HP support ?

Good luck.

Hello Kim,

How often does the system report the fan events? Is it intermittent or solid? Did the EMS log another entry for the fan connection after logging the fan discinnection entry? It is better you attach the EMS output copy for our reference.

L-class system has the N+1 fan redundancy and the system can be up and running with 1 fan failure. I would suggest you will check the fan status with the GSP PS command when the event was logged.

GSP> ps

If the system has "failure" entry something like below, I would suggest you will contact HP call center for more troubleshooting.

What is your system model?
If your system is support redundancy, it operate
any problem. Send your system's log to HP Response Center.
event.log, syslog, GSP log...
Have a nice day....
