Because the system is left with only one functional root partition, you should
immediately restore the primary JUNOS Software image. This can be done by installing
a new image using the CLI or J-Web. The newly installed image will become the
primary image, and the device will boot from it on the next reboot.
CLI Changes
This section describes CLI changes when the SRX Series device runs JUNOS Release
10.1 with the dual-root partitioning scheme.

Changes to the Snapshot CLI
On an SRX Series device, you can configure the primary or secondary boot device
with a “snapshot” of the current configuration, default factory configuration, or rescue
configuration. The snapshot feature is modified to support dual-root partitioning.
The options
as-primary
,
swap-size
,
config-size
,
root-size
,
var-size
, and
data-size
are not
supported on SRX Series devices.
With the dual-root partitioning scheme, performing a snapshot to a USB storage
device that is less than 1 GB is not supported.
With the dual-root partitioning scheme, you must use the
partition
option when
performing a snapshot. If the
partition
option is not specified, the snapshot operation
fails with a message that the media needs to be partitioned for snapshot.
The output for the
show system snapshot
CLI command is changed in devices with
dual-root partitions to show the snapshot information for both root partitions:
user@host>
show system snapshot media usb
Information for snapshot on usb (/dev/da1s1a) (primary)
Creation date: Jul 24 16:16:01 2009
JUNOS version on snapshot:
junos : 10.1I20090723_1017-domestic
Information for snapshot on usb (/dev/da1s2a) (backup)
Creation date: Jul 24 16:17:13 2009
JUNOS version on snapshot:
junos : 10.1I20090724_0719-domestic
NOTE:
You can use the
show system snapshot media internal
command to determine
the partitioning scheme present on the internal media. Information for only one root
is displayed for single-root partitioning, whereas information for both roots is
displayed for dual-root partitioning.
