EVA4400 cache battery failure forces SAN offline

[Stu Gepp]

Mauro,

You have summed it up nicely.

It is for this reason I have obtained a complete set of batteries for all my EVA4400s and will shortly have them on site right next to each EVA. I wanted to take HP logistics out of the time line to get replacements fitted.

The nice thing is that the expiration date on the batteries (shelf life) says 2099-12-12. I hope to have retired by the time these batteries are no longer any good.

I'd be a bit dubious about that... Sure looks like an auto generated date routine gone wrong to me.

Previous EVA and HSG batteries had a 3 year shelf life, if I recall correctly. I somehow doubt that the battery technology has changed sufficiently to increase that to 90 years !

Cheers,

Rob

Does anyone have the part number for these batteries? I would like to order some too.

[Stu Gepp]

CommandView EVA shows the replacement part number as 460581-001.

I can't verify that this is what I was sent as I have already dispatched my spares to the datacentres.

PartSurfer is your friend:

460581-001 is the correct number.

Thanks Stu, thanks Rob.

I have a quote now from a local reseller. They do not know when they can get hold of these though.

Found this CA this morning:

Finally managed to get spare cache battery modules for my 2 EVA4400's.


I notice flash backed write cache is available for the Smart Array family, perhaps this will be available for the EVA family at some point.
