Mon, Sept 14th - PDU Upgrade Racks D5 and D6
Open, MediumPublicRequest

Description

ps1-d5-eqiad & ps2-d5-eqiad:

  • - apply asset tags to each tower (both primary and link towers) as well has hostname labels.
  • - update netbox for new pdus (ps1 and ps2)
  • - check the existing PDU and all connected cables. Ensure all are properly seated and all items are receiving power from both A and B sides before continuing. Anything not seated or not receiving dual power will be rebooted by continuing this checklist.
  • - install new PDU brackets for the link tower in the rack (see above note on orientation of the brackets.)
  • - install link PDU into the cabinet
  • - de-power old/existing B side power, and plug in new B side link PDU
  • - migrate all B side power connections to new link PDU
  • - Note all B side power connections, input into netbox for every single power port used.
  • - When relocating power cables, please try to ensure that the A and B sides use the same port. If server bast1001 plugs into port 5 on tower B, please also have it plug into port 5 on tower A.
  • - audit all B side connections to ensure all devices are receiving full power on the B side connection (any not receiving power will be rebooted when we move the A side connections next.)
  • - BEFORE UNPLUGGING THE A SIDE ORIGINAL TOWER: Login to the PDU via the HTTPS interface and reset it to factory defaults!
  • - Unmount existing PDU tower and set aside (if possible) to install new PDU brackets into the rack.
  • - Install new PDU tower into the rack, and route power cable for easy cut-over.
  • - de-power old/existing A side power, and plug in new A side link PDU
  • - migrate all A side power connections to new link PDU
  • - audit all A side connections to ensure all devices are receiving full power on the A side connection.
  • - connect serial to new PDU, ensure serial connection is functional
  • - setup network configuration of new PDU via serial
  • - setup remaining pdu configuration via https interface
  • - update puppet repo file: modules/facilities/manifests/init.pp to add the senty4 line to the PDU entry.
  • - update librenms to reflect new PDU. (unclear if you must delete the old and add new, or if the new will update when its wholly online, so far only done via removing old and adding new device.
  • - Update IP address entries in netbox, for now just leave the ip tied to old PDU netbox entry (rob will change this to more detailed entry later)
  • - ensure all errors clear in icinga and netbox after work completes
  • - attach temp/humidity leads

Marostegui moved this task from Triage to Next on the DBA board.

Please take extra care of db1122 as it is an eqiad master and lots of slaves hang from it. We might stop mysql there just in case prior the maintenance.

Mentioned in SAL (#wikimedia-operations) [2020-09-09T11:03:53Z] <marostegui> Stop MySQL on s2 eqiad master to prepare for the PDU maintenance (this will generate lag on s2 on labsdb) T261453

Update: Due to the accident/injury at the data center today, @Jclark-ctr will try and complete the upgrade of these 2x PDUs tomorrow (on Thur, Sept 10) after T261454 is completed, should there be enough time during the scheduled maintenance window of 12pm-4pm UTC.

RobH updated the task description. (Show Details)Wed, Sep 9, 5:48 PM

Latest update: Due to another separate injury, the upgrades for these 2x PDUs will be postponed again for a later date. No PDU upgrades for the rest of this week. Thanks, Willy

Please note that ps1-d6-eqiad does not see ps2-d6-eqiad, I suspect it is not linked correctly via cable.

The new netbox entries for these two PDUs have not yet been created by the on-site, so I cannot migrate the ip info yet.

RobH added a comment.Mon, Sep 14, 5:00 PM

PDUs show correctly in icinga, so the errors for them are legit: ps1-d6-eqiad doesn't see ps2, so it has errors.
