Go to SolutionDEGRADED Battery status H700 Raid adapter
Hi,
Just got an email from monitoring system.
WARNING: [XYZABC] Cache Battery 0 in controller 1 is Degraded (Non-Critical) [probably harmless]br/------ SYSTEM: PowerEdge R310, SN:XYZABC
Checked Battery status under Main System Chassis-Good. However, battery status for H700 RAID Adapter shows Degrade state. O/p is pasted below.
| Name | Battery 0 |
| State | Degraded |
| Predicted Capacity Status | Ready |
| Learn State | Due |
| Next Learn Time | 0 hours |
| Maximum Learn Delay | 7 days 0 hours |
| Learn Mode | Auto |
This is PowerEdge R310.
Firmware:
BIOS:
| Manufacturer | Dell Inc. |
| Version | 1.8.2 |
| Release Date | 08/17/2011 |
H700 Adapter :
| Firmware Version | 12.10.2-0004 |
| Driver Version | 00.00.04.31-RH1 |
BMC:
| Baseboard Management Controller | 1.70 |
| Unified Server Configurator | 1.4.0.25344 |
What is there I can try myself before I contact Dell support? This is just warning so obviously I am not going to call dell support but email them, and that I believe will take 2 days for me to get a response from them..
Thanks in advance.

Honestly, playing the odds, upgrading the firmware probably isn't going to "fix" the status, so if you are looking for a single reboot only, then wait for the battery. Just know that it is good preventative maintenance to keep system firmware up to date, as many unexpected drive failures/timeouts, battery degradation, error recovery/foreign configuration handling, memory errors, PCI/CPU errors, etc. can be fixed before they happen.
4/26 is right inline with the 90-day cycle ... I suspect it entered degraded when the learn cycle was supposed to begin, because it couldn't begin; still, I would think, there would be a controller log entry to that effect. I'm also not surewhat time is is for you ... MST, it is not yet 5 hours from the time is listed to start.

And, as Chris said, because the controller is responsible for monitoring and managing the battery, having the controller firmware up to date can be important.
Thanks guys, appreciate your quick helpful replies.
Makes sense what you just said about learn cycle.
I see this in the event log for January.

but don't see anything like that today

I recently had a dell engineer come and replace battery on PE R310 as server got rebooted abruptly and was using H700 adapter for internal raid. That time I didn't see H700 adapter Battery degraded but support technician said BBU needed replacement after seeing DSET o/p. Makes me wonder if there was a bad batch of batteries :(
On that R310 all firmwares were up to date.
I will wait till the end of day today and give dell support a call but if this status(DEGRADED) is confirmation of BBU being bad, then I don't really wannt to take system down two times being in production. I will want to do firmware update and BBU replacement , both at same time.

UG,
The server and controller look to be slightly out of date. The battery error can happen due to it being behind.
What is the OS on the server and I can get you the links you need?

If your January log goes back far enough, you might be able to get a sense for how long it will take, but it sounds like part of the cycle to me.
Oh, I agree with your note on keeping firmware up 2 date. Right now I don't have any mechanism that tells me that new firmware is available. If there is anything I could use to keep myself updated regarding new package/firmware updates available for a server/Service Tag, I'd be willing to use it. If there is anything like this on Dell site, please let me know. Thanks.
Thanks for continuing to advice.
I see more items in the log now.
2415 Thu Apr 26 10:05:26 2012 Storage Service Controller battery is discharging: Battery 0 Controller 1
2248 Thu Apr 26 10:05:26 2012 Storage Service The controller battery is executing a Learn cycle.: Battery 0 Controller 1
2176 Thu Apr 26 10:04:21 2012 Storage Service The controller battery Learn cycle has started.: Battery 0 Controller 1
By the way I am using CDT(US Central time)
Battery properties for H700 adapter are now as below.
Name Battery 0
State Learning
Predicted Capacity Status Unknown
Learn State Active
Next Learn Time 0 hours
Maximum Learn Delay 7 days 0 hours
Learn Mode Auto
I just hope that what you said is exactly what is happening here:)
Everything is in good state now. Battery status changed to Ready from DEGRADED.

If you are in the States or Canada, you can call them 24/7 and get a response immediately. Every 90 days, the PERC's initiate a "learning cycle", which completely drains the battery, then recharges it. During this time, write cache is turned off, an warning and error thresholds are tripped for the battery charge. O would give it up to 24 hours; if it hasn't returned to optimal/normal status, then call Support.
If you want to confirm the learning cycle is responsible, the controller log will usually log when this event is going on.
