JUNOS 10.x Dual-Root Partitioning Scheme
« on: January 25, 2011, 04:28:52 PM »
I just unboxed a new Juniper SRX 210 that was pre-installed with JUNOS 10.0R3.10 with a Dual-Root partitioning scheme.

Is it safe to use the same process to upgrade a single-root partitioned system with a dual-root partitioned system?

request system software add ftp://10.1.1.1/junos-srxsme-10.2R3.10-domestic.tgz no-copy no-validate

or should I use this command;

request system software add ftp://10.1.1.1/junos-srxsme-10.2R3.10-domestic.tgz no-copy no-validate partition

I've intentionally left off the reboot because I like to see the results before the router reboots itself.

If you are planning to use the "partition" keyword  (which dual partitions your srx for FileSystem resiliency), I'd suggest you avoid using the "no-validate" keyword.  This is because if your image is corrupted for some reason, you could be left with an unbootable device. The upgrade with validation may take longer, but in my opinion, since its a one time thing, its worth the wait.
