QFX5100 VCF Backup RE dropping out

‎05-16-2016 02:56 AM

I have a VCF of all qfx5100 with 14.1X53-D35.3 code.

 

suddenly a commit cant reach the backup RE.

seems to be running the VCF protocols but comms are down?

 

rebooted the member, zeroised the member and has come back up and is back in VCF but still the same.

 

a show virtual-chassis status shows the node.

a show chassis hardware doesnt show the node.

 

I login to the node and see:

{backup:1}
root> show chassis hardware
Hardware inventory:
Item Version Part number Serial number Description
Chassis
Pseudo CB 1
Fan Tray 0 QFX5100 Fan Tray 0, Front to Back Airflow - AFO
Fan Tray 1 QFX5100 Fan Tray 1, Front to Back Airflow - AFO
Fan Tray 2 QFX5100 Fan Tray 2, Front to Back Airflow - AFO
Fan Tray 3 QFX5100 Fan Tray 3, Front to Back Airflow - AFO
Fan Tray 4 QFX5100 Fan Tray 4, Front to Back Airflow - AFO

 

wheres the rest of the hardware?

This looks like  a serious hardware issue on the switch and you have already done the obvious steps.  I would open an official JTAC case and see if you need an RMA or if this is a bug that can be resolved in software.
