[ ProLiant ML350 G5 ] Smart Array E200i battery failure?

[MelvinN]

Hello,

We have a ProLiant ML350 G5 server which gave me the notice to replace the battery of the E200i controller?

Where can I get such battery? En which one do I need?

Thanks in advance!

Yours sincerly,

Melvin

hi Melvin,

You need this battery:

HP part number: 307132-001

Description: Battery : 3.6V battery pack assembly - 500mAh nickel metal hydride (NiMH) - Oval shaped, 12.5mm (0.5in) high, 38mm (1.5in) wide, and 77mm (3.0in) long


good luck... er, bonne chance. If you appreciate the answers, we appreciate the points!

Hi WFH-WI,

Thanks for your reply!

After replacing the battery do i have to do something else? Like re-configure the raid array or something like that?

[Nikliz]

I would've recommend to verify the Firmware on your controller and if it's out of date to upgrade it to the latest version and wait for at least 72hrs and re run the ADU. But, if you keep having the error msg after that to go ahead and replace the battery. After that you don't need to make any other changes.

Cheers!
FYI:Also verify how many batteries you'r controller is currently supporting :D

[WFHC-WI]

Nikliz is right, no need to reconfigure your array or do any other actions once you have replaced this battery.

Easy as it gets!

[MelvinN]

Thanks! The firmware is v1.20... very old, i guess.

But I don't think it says "replace battery" without reason. If I don't replace the battery... what will happen?

And how exactly do i replace the battery?

I'm a servernewb... sorry.

If you don't replace the battery, it may not have enough charge to support the cache if there's a power failure. If the system detects the battery is dead, it may disable the cache altogether until the charge level comes back up, this can have a severe impact on your I/O rates.

I agree with the rest, verify your firmware is up to date first, sometimes the new firmware has better verification/management on charging the battery. remember to wait 72 hours to give the system enough time to trickle-charge the battery.

If you do have to replace the battery, it will be connected to the cache module with a few easy to release clips. Just power down the server (properly of course), remove the cache module from the system, and swap out the batteries. It can take up to 72 hours for the battery to get back to full charge.

If you like, HP offers a page where you can view most server models, and how to replace/remove many parts in them at http://h20464.www2.hp.com/index.html

Here's a direct link to the process to get the cache module out: http://h20464.www2.hp.com/results.htm?SID=1121586&MEID=8B57711E-5E25-479C-9F6A-BE5916307139

Hope this helps.

Thanks!

It can't go wrong with this information... great! :)

I noticed that there are two bateries. How can I determine which one is bad?

[Johan Guldmyr]

Jade: I think there are more than one battery cell inside the battery pack and that one of them is faulty. You replace the whole battery pack (one spare part). I would not advise you to try to replace individual cells inside there, unless you know what you're doing.

Or do you actually have two battery packs connected to the controller?

[JaceM]

1 pack. Thanks!!

Hello,

I am having the same error, so I am going to order part #307132-001.  The links to the "Self Help" show how to remove the cache memory SIMM/DIMM, but don't show how to replace the battery.  Will this be a "common sense" replacement once I get the battery?  I've searched HP's Web site for any documentation on replacing the BBWC Battery, but can only find replacing the entire memory module.

Many thanks,

Bruce

Hi All

i am also a newbe to the server club and also have a problem with the battery pack. i ahve found some top ideas about this subject in the above but i can give you my 10 cents worth the battery pack comes of very easly but mack sure the when you replace it with the new one check the 2 clips at the botom of the board have locked in. don't forget to follow static precautions and earth your self.

I am just wondering - would it be easiest to just replace the whole battery-backed write cache?  If so, do I need to rebuild the array after or will there be any configuration involved?

I know very little about server hardware management.

Thanks.

[Robert Klarmann]

Hello,

no - you have to replace only the battery module - it is clipped behind the cache module. It is easy to remove from the cache module. After clipping in the new battery you put the cache module back in place on the controller - close the server and power it up.

If you have too much money to spend you can also replace the complete BBWC module with battery :-) but as said befor - you should not ;-)

The battery will be charged and the controller will then reenable the write cache. That's all - no need to change config or array settings.

Regards

Robert

[DarthVal]

Thanks, Robert.  This will be much easier, since I am having difficulty determining exactly which part # I would need for the cache.  :)

[DarthVal]

Okay, I have replaced the battery, rebooted the server and waiting a few days to see if that battery just needed to charge.

I am still getting the same message.

Do I need to reboot again to be able to see that the battery has been charged?  Is there something else that I need to do to get it to recognize the new battery?

[DarthVal]

I have replaced both the battery and battery backed cache card.  I have installed the latest firmware.

I am still getting this error message.

Any ideas on what else to try?

[VelocityTracy]

413486-001 is a part number for 128mb cache. but of course there are other sizes. im unsure what you're using.

[VelocityTracy]

did you get this figured out already? If you are still getting the error i can only assume that either the battery that you bought was bad. i see this a lot. these are getting pretty old. OR the gold connections on the cache need cleaning. You could try mix and matching the old battery new cache, new battery old cache see if it still gives the errors. I'm at a loss otherwise.

[IT803]

I have an older ML350 with an e200i and a 128 MB cache module with a failed battery.  Yellow light flashing on the BBWC and the ADU reporting battery failure.

When the battery failed, I bought a new one but that failed to charge.  SO I bought 2 new ones from a different vendor - both new, HP parts (274779-001).  Neither of those batteries charged either.

So I bought a new BBWC (356272-001) with a bettery.  It did not charge either!  I also tried all of the batteries in the new BBWC.

So, what to do now?  Anyone have any ideas?  Thanks

I have simular issue,  replaced battery twice in last few months, first one was HP part , 2nd was HQRP compatable,

I am going to check voltage on the battery that is currently installed just to see...

The one I pulled a few months ago has 2.6 volts on it after sitting for months so I wonder what the newer one has

I will report back.

[IMR-TECH]

Hello - Having the same issue as well.

Battery failed destroyed all information on the server.

We ordered new battery and installed now its flashing amber and says cannot charge in the posting messages at boot up.

anyone have a solutions on this?

thank you for the time.

I am having the same issue.  Tried new battery and new cache board and mix of each, old with new, also new with old.  All combinations equal no joy!  I can configure RAID 0 with bad battery state.  I believe I can reconfigure as RAID 5 (without caching, but there will be a perfomance hit) if I do fresh.
