SRX high end devices may not bring up the FPCs after first enabling cluster, or after an upgrade, or after an abnormal reboot.

Even after waiting 30 minutes the hardware does not start to come up.

{secondary:node1}
root@SRX-4600> show chassis fpc pic-status 
node0:
--------------------------------------------------------------------------
Slot 0   Present       SRX4600 SPM                                   
Slot 1   Present       SRX4600 MPC        

When configured for clustering, the SRX high end devices usually need a minimum amount of configuration in order to know how to configure and bring up the FPCs. 

If there is no configuration, please add the following. You can replace any of these values with the known proper values for your deployment.

set groups node0 system host-name node0
set groups node1 system host-name node1
set apply-groups "${node}"
set chassis cluster reth-count 1
set chassis cluster redundancy-group 0 node 0 priority 200
set chassis cluster redundancy-group 0 node 1 priority 100
set chassis cluster redundancy-group 1 node 0 priority 200
set chassis cluster redundancy-group 1 node 1 priority 100
set interfaces reth0 redundant-ether-options redundancy-group 1
set interfaces fab0 fabric-options member-interfaces xe-0/0/7
set interfaces fab1 fabric-options member-interfaces xe-5/0/8

***** If this is an SRX5K, we also must define control ports.

set chassis cluster control-ports fpc 0 port 0
set chassis cluster control-ports fpc 12 port 0

These configurations can be used as a placeholder until the proper configurations are available.

If the SRX looks like it does have the configuration but you see this behavior with the FPCs staying offline after something such as an upgrade, go into configure mode and run a "commit check". If the commit check fails, correct the configuration untiil it passes and then commit the updates.

If the minimum configuration is present, and the configuration does commit properly, then it may be appropriate to open a JTAC case to investigate why the hardware will not come online.
