Description

This task will track the installation of (4) new RE-S-X6-64G-S modules for installation/swap (2 in each) in cr[12]-codfw.

This work will require coordination with the netops team for scheduling and execution.

  • Receive in and update procurement task T218794
  • Schedule work with @ayounsi and update this checklist with other steps.

Window steps:

  • Downtime alerting (Icinga/Librenms)
  • Ensure VRRP master is on the other node
  • Tune OSPF cost to drain transport links terminating on that device
  • Drain local BGP peers (graceful shutdown + deactivate)
  • Fail LVS over the ones connected to the other router
  • Ensure RE is connected to serial console
  • From the doc do Removing the Routing Engine and Installing the Routing Engine RE-S-X6-64G for the backup routing engine
  • Warn on IRC that it's going to be bumpy
  • From the doc do Verifying and Configuring the Upgraded Routing Engine as the Master All FPCs reboot after this step.
  • Verify device is healthy (logs, OSPF/BGP sessions, alarms, alerting)
  • Do the 5 steps above for the other RE (now backup)
  • Rollback BGP/OSPF/LVS/VRRP changes

The new backup routing engine is not coming online.
Rolling back to the old one is not working neither.
Opened JTAC Service Request ID: 2019-0731-0446 .

• ayounsi added a comment.Jul 31 2019, 8:34 PM

First JTAC suggestion is to re-seat the SCB. We didn't do that today as the doc wasn't clear if it could be done with the router online.
JTAC is looking into the logs.

• ayounsi added a comment.Jul 31 2019, 8:38 PM

Also noticed the following while looking at the doc again today:

  1. Use the request chassis routing-engine master switch command to make the Routing Engine RE-S-X6-64G (RE1) the master Routing Engine. All FPCs reboot after this step.

So this mean the RE failover will have production impact, and should be prepared accordingly.
