Please would you replace the RAID battery in an-worker1078.eqiad.wmnet

This is yet another Hadoop worker with a failed RAID controller battery. I'd be grateful if you could change it please.

If you let me know when would be a convenient time for you to replace it, I can shut down the machine ahead of time.

• - Provide FQDN of system.
• - If other than a hard drive issue, please depool the machine (and confirm that it’s been depooled) for us to work on it. If not, please provide time frame for us to take the machine down.
• - Put system into a failed state in Netbox.
• - Provide urgency of request, along with justification (redundancy, dependencies, etc)
• - Describe issue and/or attach hardware failure log. (Refer to https://wikitech.wikimedia.org/wiki/Dc-operations/Hardware_Troubleshooting_Runbook if you need help)
• - Assign correct project tag and appropriate owner (based on above). Also, please ensure the service owners of the host(s) are added as subscribers to provide any additional input.
