After upgrading Junos version on 650srx, the new version was working fine...But after while box was needed to reboot. We did. After reboot, we realised previous junos version had been loaded and now it is still running... As it is running what should we do to force the latest version permanently working?
And also can I ask you guys about where we made a mistake when upgrading new junos version?
Re: booting previous Junos OS version after upgrade
I could only think of two options:
1. SRX boot from backup partition:
a-) Check "> show system storage partitions", "> show chassis alarms" and "> show system snapshot media internal".
b-) Recover primary partition: "> request system snapshot slice alternate"
c-) I suggest to reboot the SRX and check that everything is working fine with the commands listed on step a.
2. Someone might have ran "request system software rollback" so when you rebooted the SRX, it started to use the previous Junos version. You could check this on the interactive-commands log file (if configured):
d-) check > show log interactive-commands | match "request system software rollback"
Please mark my answer as the Solution if it applies.
