SRX

Hi, I have SRX1500 running Junos OS with upgraded FreeBSD and I want to make a recovery snapshot just like on the previous branch series devices with slice alternate for case with failure booting. I also saw a KB artice https://kb.juniper.net/InfoCenter/index?page=content&id=KB34038

Output when I trying to make a snapshot

>request system snapshot recovery 
error: command is not valid on the srx1500

OK, I can understand that this command isn't support on TVP platforms like SRX1500, but I don't understand next things:

1. How I can make a recovery snapshot and be sure that device will booted when my primary volume corrupted? Should I take care of resiliency at boot in my case?
2. Is it possible to make a backup on a separate medium (on TVP platform), and then just plug it in and boot?
3. What is ToR Velocity Program? What benefits I can take with TVP architecture? What this mean in practice?

Thanks.

Hello , 

Snapshot is not supported on TVP platforms with Linux kernal . You can make recovery snapshot on USB using the install media availible in download site from Juniper :

Hello 

To add , if the primary partition is corrupted , it will be taken care by the backup /recovery :

root@srx1500> show system software backup
Backup JUNOS package information:
File name: /recovery/images/install-media-srx-700e-junos-19.1R3.9.tgz
File size: 1176466362

Hi ZohTah3o,

TVP has a different architecture differentiating PFE from Junos and additional API compatibility. As per my understanding SRX1500, SRX4100, SRX4200 are the devices with TVP architecture in SRX series. 

From a working/practical perspective, I believe there would not be any change that you should be worried about. The difference would lie with the underlying architecture and internal processing flow.

Hope this helps 🙂

Hi ZohTah3o,

Good day!!

I hope you are doing great.

From the case notes I understand that you have some problems while executing a system snapshot on your SRX1500. 

Please notice that the snapshot feature is only supported on old and new Branch SRX devices:
https://www.juniper.net/documentation/en_US/junos/topics/concept/security-dual-root-partitioning-scheme-overview.html

The SRX1500, is one of the High-End Data Center SRX devices and only have a single partition.

In order to perform a snapshot of this device’s image you need to plug in a usb and perform the steps described on the following document:
https://www.juniper.net/documentation/en_US/junos/topics/reference/command-summary/request-system-snapshot-partition.html

Please let me know if you have any other doubts.

I will be looking forward to your response.

Hello ,

There is a small clarification here . SRX1500 is a TVP platform ( unlike other SRX5K HE devices )  and "request system snapshot" is not suppoted on TVP platform :

The error occurs because the system snapshot option is not supported in TVP platforms ( reference KB:34038 ) . 

So if you try to perform the action in :

https://www.juniper.net/documentation/en_US/junos/topics/reference/command-summary/request-system-snapshot-partition.html

It may fail in SRX1500 ( TVP platforms )  .
