Booting the Switch
ARX-2500 Hardware Installation Guide 3 - 7
When Replacing a Standalone ARX
If you replace a standalone ARX, the replacement ARX must re-import all
of the managed volumes hosted by the failed ARX. This re-import occurs
automatically at the end of the switch replacement process. With a
standalone installation, the configuration is not saved on a backup switch.
Thus, you have to save key pieces of configuration data
prior to the switch
failure.
Every ARX keeps its local network parameters in running-config . To
replace a standalone switch, you need to copy from running-config:
• Master key (extracted and wrapped)
• Master key wrapping key password
When Replacing a Member of a Redundant Pair
Every redundant pair of ARX devices shares a single global-config ,
containing namespace and service parameters.
An ARX startup-config contains both running-config and global-config in a
single file. Therefore, a redundant pair requires two or more saved
configuration files:
• two startup-configs (one per ARX), or
• two running-configs (one per ARX) and a single global-config
These items and the procedures for saving them are described fully in the
ARX Site Planning Guide , Best Practice: Regularly Saving the
Configuration . For details, consult that guide available from the ARX
Manager).
Choosing Switch Replacement
When the initial-boot script asks if this is a switch replacement, answer yes
to invoke the questions required to replace the failed switch as in the
following example.
A switch replacement requires additional configuration questions.
6. Are you doing a switch replacement?
in the format 'yes' or 'no'.(default=no) # yes
Matching the Private Subnet
The next several questions ask for the switch private subnet , the private
VLAN for that subnet, and the VLAN for a private metalog subnet .
If the failed switch was in a redundant pair and/or Resilient-Overlay
Network (RON), the private subnets of the replacement switch should match
those of the failed switch. Each ARX uses its private subnet for
communication with other ARX devices in the same RON and/or the
switch’s redundant peer. All private subnets in the RON and/or pair are
carried by the same VLAN. This private VLAN, and the separate metalog
VLAN, must be reserved for ARX traffic only.
