ML350G5 :Raid Battery is not charged

[Ikarisan]

Hello!

I run five ML350-G5 server with Ubuntu Linux.Every server uses a RAID5 harddisk system. To increase the performance I installed the 128MB cache module in each one.But the batteries are never charged. Meanwhile the voltage of the batteries reached 2,7V and the E200i controlles refused to use the cache. :(

Why are the batteries not charged? Do I have to connect them directly to the power supply? There are two connectors on the upper corners of the PCB. What are they for?

Thank you for your help!!!

Hi,

Any particular error message generated during POST or in ACU/ADU or in Event Logs about E200i or Cache module?

I have attached an image of system board components, #13 is the slot for connecting E200i cache module.

If I am not wrong, the cache and batteries are attached togeather so no need to connect these directly to power supply.

Hope this helps.

Hi!

Only the following info is displayed during startup:

=====

Slot 0 HP Smart Array E200i Controller (128MB, v1.80) 1 Logical Drive

1794-Slot 0 Drive Array - Array Accelerator Battery Charge Low

   Array Accelerator Posted-Write Cache is temporarily disabled.

   Array Accelerator will be reenabled when batteries reach full charge.

=====

But it never reaches full charge... in none of my five ML350G server!

I get the same message as above except for one thing... It says the batteries have failed and should be replaced...

Are they replacable?

Hi,

Dont worry :)

You need to change the battery and the cache module in one go  also you need to update the firmware of the smart array E200i.

thanks

Hi!

But all five batteries didn't work from the beginning.

It must be a real contingency if they are all defective from day one. O.O

And why do I have to change the electronic components if only the battery is empty?

I can't argue to buy 5 new battery packs for a lot of money if I can't be shure that it will work. :(

You buy this server in 2011 ?

We have 3 ML350G5 with 128Mb Cache and Battery.

We already changed 1 time the battery during the 3 years of activity (2008-2012).

If your cache module is under warranty, please contact HP Support for change the battery module under warranty.

You saying the battery have a 2.7 of voltage, but the battery voltage is normaly 3.5V.

- First install the lastest Firmware.

When you measure the voltage, you mesure directly to the battery or you put a resistor ? 

When we got a defective battery, i tryed to give him a new born with a special charger for realive battery, but sincerly without a great success. You must replace it.
