Junos: vSRX Interface Un-Alignment Recovery

Please follow the below steps to perform re-alignment of the network interfaces on the vSRX appliance this can happen if you have been using a release older than D62

How to recover.
1.Shutdown node0 and node1
2. Remove all NICs
3. Power up node0 and node1 , when it reaches config loading power off node0 and node1
4. Add 3 NIC to node0 and node 1 and power on the nodes
5.Check the cluster status , node0 and node1 should see each other and fabric link should be up and working
If you require more network interfaces to be added to your appliance please follow the KB in the link below

If you are making changes to network firewalls ensure that you have a backup and a revert plan as a pro-cautionĀ

Junos: SRX Cluster Software Update

Junos: SRX Cluster Software Update

I have had the wonderful joy of performing a SRX software update and it was pretty painless so here is the procedure

  • Run the following command on each of the nodes
    • request system software add no-copy unlink
  • Once the above command has completed on all nodes complete by performing a reboot of the nodes
    • request system reboot
  • Allow the nodes to reboot and you are done!

If you are using the virtual model of the SRX appliance please ensure that you have a snapshot before performing any firmware / software updates

Junos: vSRX Cluster Gremlins

Okay so you can probably tell from the rest of the blog I work with Junos on a regular basis and I have found a bug that has been logged with Juniper that effects there current vSRX releases upto version D60. It would only effect your SRX if you running in chassis cluster mode and what would happen is that it would fail to detect the network interfaces

Anyway Juniper have agreed that it is an issue on there virtual appliance and a work around will be released hopefully the first week of December 2016

 

VMware: Cannot Complete Operation

VMware: Cannot Complete Operation

Hi Guys,

It has been a little while since I have last posted reason being that everything has been running smoothly until today!

Okay so on vCenter I was performing some VM changes in the settings and I got the following error

vmware-error3

To resolve this if you have a windows based vCenter it is much simpler just restart the VMware vCenter service on the box and off you go but if you have a vCenter appliance you are going to need to perform a full reboot

Anyway I hope this helps
