Dell Power Edge R710 PERC 6/E Controler Battery Degraded
Hi
I can see this Battery Degraded warning message in Dell Open Manage against PERC 6/E Controller. Do we need to change this battery immediately or there is no harm to keep like this? Appreciate any one can explain about it and i want to know this battery contains any configuration or settings saved.
Dell MD1000 Direct Attached storage is connected through this PERC 6/E controller.
Thanks

Hi Akther
In that case, please make sure the server have a continuous power supply to prevent any power trip, just in case there is data being written to your MD at that point of time.

Hi Akther
First of all, is your PERC 6/e driver and firmware up-to-date? If not, do update to the latest and see how it goes.
If the battery is indeed degraded or failed, the write policy of the controller card will be changed from write-back to write-through. (By default is set to write-back)
Please refer to this manual on page 76, to understand more on write policy:- ftp://ftp.dell.com/Manuals/all-products/esuprt_electronics/esuprt_software/esuprt_ent_sys_mgmt/dell-opnmang-srvr-admin-v7.2_User%27s%20Guide2_en-us.pdf
The battery does not contain any information on settings or configuration. The battery protects the integrity of the cached data on the raid card providing backup power during a power outage. The battery provides up to 24 hours of backup power for the cache memory.
Hope this helps.

Hi Manfred
Thanks for the reply. All the firmware are up to date. Only Battery showing degraded. Any way if it doesn't contains any configuration or settings then we would continue with this battery warning, because this server will be decommission near future, mostly 4-5 months.
