- Check BOM against what's been received and power all equipment and test for hardware issues
- Also ensure directors and interconnects are the same version (should not be a problem yet but as 'newer' builds come old stock might pop up)
- Build and power ex4200 VCs for control plane
- I would recommended to upgrade to the JTAC recommended version of Junos on your 4200s
- Patch Up directors into control plane VCs and boot the desired 'master director'
- Complete the console initialisation and then after ~60 seconds boot the slave and complete it's initial configuration
- Patch directors into correct control ports and boot
- Turn each node into 'fabric mode'
- Patch into each interconnect and boot each node
- The directors will adjust the version of Junos if required on the QFX3500 node
- You now have a functional QFabric and can now beging to alias nodes and add them to network/server groups
Configuration (all centrally from the Director)
To build a new Fabric you need to
Create aliases for nodes
- set fabric aliases node-device SERIAL ALIAS_NAME
- set fabric resources node-group NW-NG-0 network-domain
- set fabric resources node-group NW-NG-0 node-device ALIAS_NAME_X
- set fabric resources node-group PRON-NG node-device PRON_SW1
Aggregated Interface: NODE_GROUP:ae0.0
- show fabric administration inventory director-group status all
- See the directors status and who is master
- show fabric administration inventory [terse]
- Shows all the hardware the directors have found and are including in the QFabric
- show chassis fabric connectivity
- Shows the connectivity through the interconnects to each nodes
- show fabric aliases
- See the serial to alias mappings
- show fabric inventory
- ex4200 Control Plane VCs
- QFabric Interconnects
- Director Master
- Election of master is based on uptime. Wait for ~60 to boot secondary director node
- Nodes
- I have not tested this, but I would power the network group first, with the members I would prefer to be the masters of the 'vc' first (remember each group with multiple members is an incarnation of VC - same rules apply)
Node Replacement
Replacing a node, and keeping the configuration is EXTREMELY easy due to the 'replace pattern' feature of Junos.
- Repatch cables
- replace pattern OLD_SERIAL with NEW_SERIAL
