JunOS upgrade


JUNOS upgrade on MX960 platform.

Recently I have been participating in project where we had to upgade few big boxes in the network. I have been upgrading Alcatel SR7750 TiMOS, Juniper MX960 JunOS and few Cisco boxes.
Here I am going to show you how to upgrade JunOS on Juniper MX960. I hope this can be usefull.

Juniper MX960



1.     First step is to upload new version of OS onto the primary RE0 and backup RE1.

2.     Check that you have enough space at compact flash. Needs to have more than 1GB


root> show system storage
Filesystem              Size       Used      Avail  Capacity   Mounted on
/dev/ad0s1a             3.5G       484M       2.8G       14%  /
devfs                   1.0K       1.0K         0B      100%  /dev
/dev/md0                 76M        76M         0B      100%  /packages/mnt/jbase
/dev/md1                 27M        27M         0B      100%  /packages/mnt/jkernel-14.1R1.10
/dev/md2                127M       127M         0B      100%  /packages/mnt/jpfe-M320-14.1R1.10


2.1  Ensure that new candidate of Junos is loaded on both RE
 
file copy ftp://username:root@ftp/JUNOS/NEW_JunOS /var/tmp/NEW_JunOS
file copy /var/tmp/NEW_JunOS re0:/var/tmp/NEW_JunOS
file copy /var/tmp/NEW_JunOS re1:/var/tmp/NEW_JunOS

file list detail /var/tmp/
file list detail re0:/var/tmp
file list detail re1:/var/tmp

file checksum md5 /var/tmp/NEW_JunOS
file checksum md5 re0:/var/tmp/NEW_JunOS
file checksum md5 re1:/var/tmp/NEW_JunOS

2.2  Generate MD5 checksum against the file downloaded. Compare this to the MD5 checksum file found on the Juniper website and ensure that they are the identical.

root> file checksum md5 /var/tmp/NEW_JunOS 
MD5 (/var/tmp/NEW_JunOS) = 983542e9ffd83a4c88c35c7504f8ef974

2.3  Login to the backup RE and copy new JunOS file :


root> request routing-engine login re1



or



root> request routing-engine login other routing-engine

2.4  Generate again MD5 on RE1 and compare checksum with the one originated on RE0

root> file checksum md5 /var/tmp/NEW_JunOS
MD5 (/var/tmp/NEW_JunOS) = 983542e9ffd83a4c88c35c7504f8ef974

2.5  Do backup of your current system just to make sure that if something go wrong you will be able to recover stable system:

MASTER 

root> request system snapshot

BACKUP


root> request routing-engine login other routing-engine

root> request system snapshot




3.     Perform JunOS upgrade on RE1 (backup Routing Engine)

Currently our box is running system from RE0. We can perform JunOS upgrade on RE1 without service affecting. To install new system on RE1 we need to be sure that we are connected to correct RE.
To check that you need to type :



root> show chassis routing-engine
Routing Engine status:
  Slot 0:
    Current state                  Master
    Election priority              Master
    Temperature                 30 degrees C / 86 degrees F
    CPU temperature             29 degrees C / 84 degrees F
    DRAM                      8159 MB (8192 MB installed)
    Memory utilization          16 percent
    CPU utilization:
      User                       1 percent
      Background                 0 percent
      Kernel                     1 percent
      Interrupt                  1 percent
      Idle                      97 percent
    Model                          RE-S-1800x2

    Start time                     2014-09-19 01:04:46 BST
    Uptime                         732 days, 11 hours, 54 minutes, 35 seconds
    Last reboot reason             Router rebooted after a normal shutdown.
    Load averages:                 1 minute   5 minute  15 minute
                                       0.00       0.00       0.00
Routing Engine status:
  Slot 1:
    Current state                  Backup
    Election priority              Backup
    Temperature                 29 degrees C / 84 degrees F
    CPU temperature             30 degrees C / 86 degrees F
    DRAM                      8159 MB (8192 MB installed)
    Memory utilization          29 percent
    CPU utilization:
      User                      17 percent
      Background                 0 percent
      Kernel                    16 percent
      Interrupt                  3 percent
      Idle                      64 percent
    Model                          RE-S-1800x2
    Serial ID                      9009100620
    Start time                     2014-09-19 00:45:58 BST
    Uptime                         732 days, 12 hours, 13 minutes, 36 seconds
    Last reboot reason             Router rebooted after a normal shutdown.
    Load averages:                 1 minute   5 minute  15 minute
                                       0.47       0.51       0.48

If not please login to BACKUP RE using :
 
root> request routing-engine login other routing-engine
 
 
Perform upgrade on Backup RE1 and reboot RE1: 

root> request system software add /var/tmp/NEW_JunOS    
root> request system reboot


4.     Perform JunOS upgrade on RE0 (MASTER Routing Engine)

First login to the MASTER :

root> request chassis routing-engine master switch

Perform upgrade on Master RE0 and reboot RE0: 

root> request system software add /var/tmp/NEW_JunOS    
root> request system reboot
 

5.     Check version

After reboot of the master RE0 you should have the same version on both Routing Engine. 

root> show chassis routing-engine
Routing Engine status: 
Slot 0: 
Current state Backup 
Election priority Master (default) 
Routing Engine status: 
Slot 1: 
Current state Master 
Election priority Backup (default)
  
        In one of my case output was like this :



root> show chassis routing-engine
Routing Engine status: 
Slot 0: 
Current state Backup 
Election priority Master (default) 
Routing Engine status: 
Slot 1: 
Current state Master 
Election priority Backup (default)
 
root> show version invoke-on all-routing-engines
