Description

This task will track the migration of the ps1 and ps2 to be replaced with new PDUs in rack B2-eqiad.

Each server & switch will need to have potential downtime scheduled, since this will be a live power change of the PDU towers.

These racks have a single tower for the old PDU (with and A and B side), with the new PDUs having independent A and B towers.

- schedule downtime for the entire list of switches and servers.
- Wire up one of the two towers, energize, and relocate power to it from existing/old pdu tower (now de-energized).
- confirm entire list of switches, routers, and servers have had their power restored from the new pdu tower
- Once new PDU tower is confirmed online, move on to next steps.
- Wire up remaining tower, energize, and relocate power to it from existing/old pdu tower (now de-energized).
- confirm entire list of switches, routers, and servers have had their power restored from the new pdu tower
- connect via serial / confirm serial connection works
- setup PDU following directions on https://wikitech.wikimedia.org/wiki/Platform-specific_documentation/ServerTech#Initial_Setup
- update PDU model in puppet per T233129.

cp1079 and cp1080 just need normal depooling process here.

From the DB side, this can be done after Thursday 25th as db1072 will no longer be a master

As of today, db1072 is no longer a master (T228243#5363931), so this rack is also good to go. db1072 will be decommissioned in a few days

I will repool the db host, as I do not want to leave them off for a long time. Let me know if more operations on this row are planned at a later time.

I've completed all setup work from the software side for the PDU at this time.
