NERC Maintenance 1/7/2025

[hakasapl]

Purpose

• Transfer management of NERC top-of-rack switches to MOCA
• Move uplinks from Harvard aggregation to new NERC core Cisco switches for all TORS
• Return borrowed TORS in R2-PC-C06 and R7-PC-C03
• Relocate ALL equipment in R7-PC-C03 to R2-PC-C21

Maintenance Timeframe / Affected Clusters

All NERC Clusters (Openstack and Openshift)
1/7/2025 9 AM Eastern Time to 1/8/2025 9 AM Eastern Time

Pre-Maintenance Tasks

• Order new optics and uplinks required for connection to new NERC core
• Run uplink cables to racks and let dangle for now
• Post announcement to users (Communication Plan for NERC Core Network Upgrade #798)
• Make MOC user on required Harvard switches so it is ready
• Write manifests and dry run configuration for core and TORS
• Configure MSTP on NERC core switches and coordinate with Harvard for VLAN uplink (Switch from RSTP to MSTP in MOCA Network CCI-MOC/ops-issues#1336)
• Install single TORS in R2-PC-C21 and configure uplink
• Review this plan with NERC admins and Nick Amento

Maintenance Tasks

• NERC ADMINS: Bring down all services gracefully
• Move core uplink to Harvard from MOC-CORE to NERC-CORE
• Add link from MOC-CORE to NERC-CORE for NERC VLANs
• Move uplink for R8-PA-C23 from MOC-CORE to NERC-CORE (R6-PB-C02) - Cable already in rack, just port swap
• Move uplink for R1-PC-C20 from Harvard aggregation to NERC-CORE (R6-PB-C02) - Cable already in rack, just port swap
• Remove 2x Harvard switches in R2-PB-C06
• Install 2x Dell S5048-ON switches in R2-PC-C06 to replace existing switches
• Move uplink for R2-PC-C06 from Harvard aggregation to NERC-CORE (R6-PB-C02) - Cable already in rack, just port swap
• Move equipment from R7-PC-C03 to R2-PC-C21 and cable up with new switch in R2-PC-C21
• NERC ADMINS: Bring up all services and verify all networks are behaving the same (maintenance should be transparent from the perspective of NERC hardware)

Support

• One other person on-site would be good to help with moving stuff around (Techsquare?)
• Nick Amento is available for remote support for anything relating to networking
