Description

ps1-d7-eqiad & ps2-d7-eqiad:

  • - apply asset tags to each tower (both primary and link towers) as well has hostname labels.
  • - netbox updated
  • - 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
  • - Note all A side power connections, input into netbox for every single power port used.
  • - 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
  • - (Rob) setup network configuration of new PDU via serial
  • - (Rob) setup remaining pdu configuration via https interface
  • - (Rob) update puppet repo file: modules/facilities/manifests/init.pp to add the senty4 line to the PDU entry.
  • - (Rob) 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.
  • - (Rob) Update IP address entries in netbox, for now just leave the ip tied to old PDU netbox entry.
  • - ensure all errors clear in icinga and netbox after work completes

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

Please take extra care with db1123, db1093 and db1109, they are an eqiad masters and lots of slaves hang from them. We might stop mysql just in case.

Marostegui moved this task from Next to In progress on the DBA board.Thu, Sep 10, 5:53 AM

Apologies for the last minute change, the upgrades for these 2x PDUs will be postponed until a later date. Both dc-ops engineers at eqiad are recovering from independent injuries (both earlier today), and will be out the rest of the week. Thanks, Willy
