MSA1000 temperature overheat

[CLEB]

I was receiving this message in my IML:

"External Storage System Overheating (Chassis SGM051627V, Slot 1, Zone Unknown, Location Storage, Temperature Unknown)"

I couldn't find any problems with fans.
This has stopped appearing now but was wondering why it appeared in the first place.

Hi,

Didn't you have a cooling problem in your computerroom around the MSA1000??

[CLEB]

My computer room has been at an ambient temperature of 22°C.

There has not been much change around the room. As in there are not really any microclimates as we have underfloor air con blowing cool air upwards through the racks and units blowing cool air downwards too.

Carl,
Next time this happens can you pull the power supply of the MSA1000 and look for rev number, i.e. A1, B1.

I found that HP engineering advisory was recently released about false temperature readings on that model.

Basil

Do you have a link to this advisory?

[Basil Vizgin]

Unfortunally, no. I found reference to internal advisory (with its number) on Service Partner Network, but advisory itself is not available to me.

[John Kufrovich]

Carl,
The Advisory is forthcoming. When the problem occurs, use cli and issue >show globals. If the temp reads over 200c then the problem lies with the power supplies FW.

[CLEB]

John,

Thanks very much I'll monitor it. It hasn't happened for 6 days.

Is this the HP Array Configuration Utility CLI that is installed on the Server OS? I tried this command "show globals" but it said invalid command.

[John Kufrovich]

No, the controller cli.
You will not see this issue unless the temp falls below 25c.
