To transfer release files from a source ERX system to a destination ERX
system, follow the instructions in
Installing Software When a Firewall
Does Not Exist, with the following changes:
• Substitute the source ERX system for the network host.
• Omit the step about mounting the CD.
• Copy the file to the system space of the second ERX system from the
user space of the first ERX system.
host1#copy boston:/outgoing/releases/x-y-z.rel x-y-z.rel
Upgrading Systems That Are Operating with Two SRP Modules
Use this procedure if the system contains two SRP modules and is already
operating with an earlier software release. Each SRP module will keep
the system operational while you upgrade the software on the other, so
that you can avoid interrupting service.
Caution: You must upgrade the software on the redundant SRP module when you
upgrade the software on the primary SRP module. This action prevents the
redundant SRP module from overwriting the new software on the primary SRP
module if the primary SRP module fails and the redundant SRP module assumes
control.
To upgrade the software on a system that is operational and contains two
SRP modules:
1 Turn off autosynchronization.
host1(config)#disable-autosync
2 Copy the new release of the software to NVS of the primary SRP
module.
host1#copy host1:x-y-z.rel x-y-z.rel
3
Save the current configuration.
host1#copy running-configuration system2.cnf
4 Specify that the ERX system should use the new software release
when it reboots.
host1(config)#boot system x-y-z.rel
5
Synchronize the NVS file system of the redundant module to that of
the primary module.
host1#synchronize
