I am getting clueless after three days on and off trying to create a snapshot onto a USB stick on a QFX3500-48S4Q.
I even tried it on two 3600's with the same result.
We have a customer that received two old 2013 QFX3500-48S4Q units that are stuck in VC mode, we tried so many things to solve this without succes.
- Reinstalling the software with jinstall-qfx-3-15.1R7.9-domestic-signed.tgz did not solve the issue.
- We have no install-media.img to install on a USB stick
- request system zeroize did not work.
- change hostname and reboot no result
- remove VC files from folder no result
- install Jinstall-qfx-3 image from the loader causes a kernel crash after validation step 20/20
Hence we try to make a USB snapshot from a unit in our lab that has no issues.
But even the snapshot cannot be created, we tried 3 different USB sticks (one 8GB usb 2.0 and two 4GB usb 2.0) that we can actually format on the switch but the command "request system snapshot partition" command works but after 15 secs we get the cli again and there seems to be no snapshot created. (see attached logs and images)
We do see that extra partitions are created but we see no Junos being installed on the USB.root@:RE:0% diff /var/tmp/before_USB.txt /var/tmp/after_USB.txt28a29,38> da1> da1s1> da1s1a> da1s1c> da1s1f> da1s2> da1s3> da1s3c> da1s3d> da1s3e
We see the below issue on the two QFX3500 units, the unit it's sub-systems are not running. Hence we want to try to boot these with a USB snapshot of our lab unit. root@W4732-C> show chassis alarmserror: the alarm-control subsystem is not running
