Description

Similar to T257153 but for EX switches.

We need to:

1/ go over all the EX switches and run show system snapshot media internal and check if there are any discrepancies between the primary and the backup partitions.

For example:

fpc8:
--------------------------------------------------------------------------
Information for snapshot on       internal (/dev/da0s1a) (primary)
Creation date: Mar 22 10:46:30 2017
JUNOS version on snapshot:
  jdocs-ex: 14.1X53-D42.3
  junos  : ex-14.1X53-D42.3
  junos-ex-4300: 14.1X53-D42.3
  jweb-ex: 14.1X53-D42.3
Information for snapshot on       internal (/dev/da0s2a) (backup)
Creation date: Dec 1 16:00:58 2016
JUNOS version on snapshot:
  jdocs-ex: 15.1R4.6                    
  junos  : ex-15.1R4.6
  junos-ex-4300: 15.1R4.6
  jweb-ex: 15.1R4.6

If any, run request system snapshot slice alternate member X (no impact)

Note that the QFXs and EX4600 only support snapshots on USB drives.

2/ Update the doc (done)
