Hello. Please could you replace the RAID controller battery in an-worker1088, when it's convenient for you to do so?

I can shut down the machine for you ahead of time. I haven't marked the machine as failed in netbox, because it's still running, just a bit more slowly than it should.

It's not super-urgent, but it's operating with reduced performance until we replace it. I've done some troubleshooting in T336077: MegaRAID error on an-worker1088 and tried upgrading the firmware of the RAID controller. However, the server is one of those in the batch identified in T318659: Multiple RAID battery failures on hadoop worker hosts so it is not unexpected that the battery should fail around this time.
