db1112 - DIMM replacement
Closed, ResolvedPublic


As detailed in the parent task, db1112 has recently had some errors on dimm B1, and hung hard yesterday.

This host is obviously out of warranty, but maybe we can get a spare DIMM somewhere and replace B1?

(Making this a dedicated dc-ops subtask so we can manage the service-level stuff in the parent task)

This is the DIMM information. I am not sure if we have one in a spare server but I will spot a check a few. @wiki_willy
we may want to purchase a DIMM.

Let me know if you're able to find a spare @Cmjohnson. If not, we can order one with @RobH. Thanks, Willy

Please coordinate with us before changing the DIMM as this host has MySQL up and running (although it is nos serving production it can still get corrupted if powered off without gracefully stopping mysql first).
Thank you!

@wiki_willy @RobH we're going to need to purchase a replacement DIMM
