Dell r610 Battery Learn Cycle.

[RedTech443]

Hello all

I am preparing to do a upgrade to a mas + mss 3 physical server configuration. 2 of the servers are showing alarms for dead or low raid battery, and according to the Avaya docs, we need to replace those batteries before any template upgrade or it will fail. My question is, after replacing the battery how long does the "learn cycle" take to clear the alarms in system platform?

This page on Dell's site lists the learn cycle at ~3 hours. I think most Avaya Dell R610s have the PERC H700 RAID controller.

From System Platform point of view the important thing is that the RAID controller is not in Write Through mode because that seriously degrades performance which could lead to some operations timing out during the upgrade you are trying to perform. You could check the RAID controller status by running 'raid_status' from a root prompt on dom0. You could also run the command '/opt/avaya/bin/raid_bbu_check.sh' to see if the alarms are still present. Both of those commands run the MegaCli command underneath the hood so if you are familiar with that you can see all kinds of stuff. System Platform runs its hardware alarming check every 5 minutes so it should clear the alarm shortly after the RAID controller is happy that the battery is good.

It should be almost immediate - as in, turn the server off, place the battery in and and when it boots up it should go into the charging status and the alarms should cease.

Is the battery charging? check from dom0

I am running this command in the dom0 CLI. I was just able to check them it has been almost 24 hours since the battery's were replaced.

[RedTech443]

Other than looking at the above stuff and checking alerts for previous alarms, is there any other way to verify the battery is good and I can proceed with any updates to the server?

 

[dialtonebone]

It looks like they are all fully charged. Are the alarms stopped?
