Entering the Private Subnet
Enter the private subnet and VLAN of the failed switch, as well as the
VLAN for the private metalog subnet. The VLANs must be unique in your
network, shared only amongst the ARX
®
es in the RON. The defaults (1002
and 1003) may be sufficient for your installation. For example:

Finding the UUID of the Failed Switch
When a switch imports storage from back-end filers, it marks each share
with its Universally-Unique ID (UUID). A replacement switch must use the
same UUID or it rejects all of the shares used by its predecessor. You also
need to set the UUID if the switch is brought back to its factory defaults; a
“Manufacturing Installation” by F5 personnel resets the switch and its
UUID.
The UUID appears at the top of a switch’s
show running-config output. For
example, this is the top of a running-config file from a switch named
“minturnA.” The UUID is highlighted in bold text:
;ARX‐6000

If the failed switch was a member of a RON, you can alternatively use show
ron
from any other RON member. This shows the UUID even if the chassis
is no longer online. For example, the following command (run on another
switch in the RON) shows the UUID for the same failed chassis,
“minturnA.” Again, the UUID is highlighted in bold text:
