Hi!

I see the following when rebooting elastic1097:

UEFI0058: Uncorrectable Memory Error has occurred because a Dual Inline Memory
Module (DIMM) is not functioning.
Check the System Event Log (SEL) to identify the non-functioning DIMM, and then
replace it.

@Cmjohnson could you please check when you have a moment?

• - 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. - was staged, so its not online for use yet, and is offline in icinga.
• - Provide urgency of request, along with justification (redundancy, dependencies, etc) - 1 of 14 newly staged hosts so while it is likely not highly urgent, but requires sub-team feedback.
• - 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.
