Ah, dammit, dc-ops missed this ticket and now 1013 is back in service on 1G. So it's no longer a good time to do this, there's real workload on that host.

@Andrew This is already located in 10g rack just needs Dac cables and connected to 10g nic. I have talked to @JHedden regarding this not sure if additional changes with switch is needed if using same ports.

@Andrew not sure if you noticed my last comment?

@jclark, typically we need to drain the workload from a host before we can swap it. It was empty when I opened this task but no longer, so this is blocked until we have a good way of draining it (and a good place to move the workload.)

Mentioned in SAL (#wikimedia-cloud) [2020-10-06T21:30:09Z] <andrewbogott> moved cloudvirt1013 out of the 'ceph' aggregate and into the 'maintenance' aggregate for T243414

Andrew raised the priority of this task from Low to Medium.

@Cmjohnson , This host is empty again; you can power it down any time. I'm happy to do the re-imaging steps but do please check the firmware.

Thank you!

From the parent task:

Note that now racks C8 and D5 are dedicated to WMCS servers (including cloudvirt). So please move servers there when able.

[operations/puppet@production] Adding new mac address for cloudvirt1013

@Andrew The server didn't have to move locations, added 10G cables, fixed the network switch, updated dhcpd file with new mac address. Verified the server will pxe boot off the 10G card now. I did not update f/w

Thanks! I'll re-image and see what I can see.
