Junos OS

Experts,

 

Due to power lost, 2200-C has been rebooted from backup partition, is there any way to fix this to start from primary partition?

 

Message:

 

WARNING: THIS DEVICE HAS BOOTED FROM THE BACKUP JUNOS IMAGE 

 

Steps:

request system snapshot media internal slice alternate
request system reboot slice alternate media internal

 

These did not work. Switch reboots from backup partition anyway

Hi,

Try to do only the first command:
request system snapshot media internal slice alternate

and then reboot : request system reboot .

request system snapshot media internal slice alternate
fpc0:
--------------------------------------------------------------------------
Formatting alternate root (/dev/da0s2a)...
Copying '/dev/da0s1a' to '/dev/da0s2a' .. (this may take a few minutes)

  s3e        123M   /var
  s4d        62M    /config

I think this did a trick. However my Juno os version is old [12.3R6.6] ..... I will try to upgrade to  12.3R12.4

 request system snapshot slice alternate
fpc0:
--------------------------------------------------------------------------
Formatting alternate root (/dev/da0s2a)...

error: timeout waiting for response from fpc0

 

but finally all is ok and both partition have same new Juno OS 

 

Thank YOU for help here !!!!!!!
