Upgrading Both Routing Engines and Rebooting the New Backup
Routing Engine Manually
When you issue the request system software in-service-upgrade command without any options, the system upgrades and reboots the
new master Routing Engine to the newer software. The new software
is placed on the new backup (old master) Routing Engine; however,
to complete the upgrade, you must issue the request system reboot command on the new backup Routing Engine.
To perform a unified ISSU using the request system software
in-service-upgrade package-name command
without any options, complete the following steps:
- Download the software package from the Juniper Networks
Support Web site, http://www.juniper.net/support/. Choose
the Canada and U.S., Worldwide, or JUNOS-FIPS edition. Place the package
on a local server. To download the package, you must have a service
contract and an access account. If you do not have an access account,
complete the registration form at the Juniper Networks Web site: https://www.juniper.net/registration/Register.jsp. - Copy the package to the router. We recommend that you
copy it to the /var/tmp directory, which is a large file
system on the hard disk.
user@host>file copy ftp://username:prompt@ftp.hostname.net/filename/var/tmp/filename - To verify the current software version running on both
Routing Engines, on the master Routing Engine issue the show version
invoke-on all-routing-engines command. The following example
shows that both Routing Engines are running JUNOS Release 9.0R1:{master}user@host> show version invoke-on all-routing-enginesre0: -------------------------------------------------------------------------- Hostname: host Model: m320 JUNOS Base OS boot [9.0R1] JUNOS Base OS Software Suite [9.0R1] JUNOS Kernel Software Suite [9.0R1] JUNOS Crypto Software Suite [9.0R1] JUNOS Packet Forwarding Engine Support (M/T Common) [9.0R1] JUNOS Packet Forwarding Engine Support (M320) [9.0R1] JUNOS Online Documentation [9.0R1] JUNOS Routing Software Suite [9.0R1] re1: -------------------------------------------------------------------------- Hostname: host1 Model: m320 JUNOS Base OS boot [9.0R1] JUNOS Base OS Software Suite [9.0R1] JUNOS Kernel Software Suite [9.0R1] JUNOS Crypto Software Suite [9.0R1] JUNOS Packet Forwarding Engine Support (M/T Common) [9.0R1] JUNOS Packet Forwarding Engine Support (M320) [9.0R1] JUNOS Online Documentation [9.0R1] JUNOS Routing Software Suite [9.0R1]
- On the master Routing Engine, issue the request system
software in-service-upgrade package-name command. The following example upgrades the current version to JUNOS

- Issue the show version invoke-on all-routing-engines command to verify that the new backup (old master) Routing Engine
(re0), is still running the previous software image, while
the new master Routing Engine (re1) is running the new software

- At this point, if you choose not to install the newer
software version on the new backup Routing Engine (re1),
you can issue the request system software delete jinstall command on it. Otherwise, to complete the upgrade, go to the next
step. - Reboot the new backup Routing Engine (re0) by
issuing the request system reboot command:{backup}user@host> request system rebootReboot the system ? [yes,no] (no) yes Shutdown NOW! Reboot consistency check bypassed - jinstall 9.0R1.2 will complete installation upon reboot [pid 6170] {backup} user@host> System going down IMMEDIATELY Connection to host closed by remote host. Connection to host closed.If you are not on the console port, you are disconnected from
the router session. - After waiting a few minutes, log in to the router again.
You are logged in to the new backup Routing Engine (re0).
To verify that both Routing Engines have been upgraded, issue the
following command:{backup}user@host> show version invoke-on all-routing-enginesre0: -------------------------------------------------------------------------- Hostname: host Model: m320 JUNOS Base OS boot [9.0R1.2] JUNOS Base OS Software Suite [9.0R1.2] JUNOS Kernel Software Suite [9.0R1.2] JUNOS Crypto Software Suite [9.0R1.2] JUNOS Packet Forwarding Engine Support (M/T Common) [9.0R1.2] JUNOS Packet Forwarding Engine Support (M320) [9.0R1.2] JUNOS Online Documentation [9.0R1.2] JUNOS Routing Software Suite [9.0R1.2] re1: -------------------------------------------------------------------------- Hostname: host1 Model: m320 JUNOS Base OS boot [9.0R1.2] JUNOS Base OS Software Suite [9.0R1.2] JUNOS Kernel Software Suite [9.0R1.2] JUNOS Crypto Software Suite [9.0R1.2] JUNOS Packet Forwarding Engine Support (M/T Common) [9.0R1.2] JUNOS Packet Forwarding Engine Support (M320) [9.0R1.2] JUNOS Online Documentation [9.0R1.2] JUNOS Routing Software Suite [9.0R1.2]
- To make re0 the master Routing Engine, issue
the following command:{backup}user@host> request chassis routing-engine master
acquireAttempt to become the master routing engine ? [yes,no] (no) yes Resolving mastership... Complete. The local routing engine becomes the master. {master} user@host> - Issue the request system snapshot command on each Routing Engine to back up the system software to
the router’s hard disk.
Note:
The root file system is backed up to /altroot, and /config is backed up to /altconfig. After you issue
the request system snapshot command, the router’s flash
and hard disks are identical. You can return to the previous version
of the software only by booting the router from removable media.
