Degradation of hard drives after extinguishing gas

Hello,

Yesterday we had a fire alarm with release of gas.
When we arrived in the datacenter, several discs were down.
Question: is that hard drives are sensitive to pressure or/and noise. If yes, where can we  find the limit ?

 

Best regards

Re: Degradation of hard drives after extinguishing gas

pressure or/and noise are not the problem, but temparature.

Sometime the gas will released with about -40 degrees celsius or even down to -78 degrees.

This may cool down your disks by 80 degrees delta or more!

 

This will damage your disks.

 

 

Anything in IML or ILO logs?

 

 

Don't know if the servers know a kind of "undertemp" condition...


Hope this helps!
Regards
Torsten.
