Problem

Boot media /dev/da0 has dual root support
WARNING: JUNOS versions running on dual partitions are not same

Solution

admin@EX> request system snapshot slice alternate
Formatting alternate root (/dev/da0s1a)…
Copying '/dev/da0s2a' to '/dev/da0s1a' .. (this may take a few minutes)
The following filesystems were archived: /

admin@EX> show system snapshot media internal Information for snapshot on internal (/dev/da0s1a) (backup) Creation date: Nov 16 18:04:49 2012 JUNOS version on snapshot: jbase : ex-11.4R2.14 jcrypto-ex: 11.4R2.14 jdocs-ex: 11.4R2.14 jroute-ex: 11.4R2.14 jswitch-ex: 11.4R2.14 jweb-ex: 11.4R2.14 Information for snapshot on internal (/dev/da0s2a) (primary) Creation date: May 2 15:56:11 2012 JUNOS version on snapshot: jbase : ex-11.4R2.14 jcrypto-ex: 11.4R2.14 jdocs-ex: 11.4R2.14 jroute-ex: 11.4R2.14 jswitch-ex: 11.4R2.14 jweb-ex: 11.4R2.14

For VC systems, you can whack the alternate partitions on all members in one go:

root@sa3-11r> request system snapshot slice alternate all-members

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
