Diagnostics AUR (DAUR)

Diagnostic Auto Unit Replacement (DAUR) enables the switch to update the diagnostic image
of the non-base unit with the diagnostic image saved in the base unit of a stack. You must
enable AAUR on the stack first.
Release 5.2 and up support DAUR. Previous software releases do not support DAUR.
Diagnostic AUR updates the diagnostic image on inserted units in the same way that AAUR
performs this function for agent code.
The DAUR process starts when you enable AAUR if there is a stand-alone unit with a different
diagnostic image connected to the stack. This process updates all the units in the stack.
When you enable or disable AAUR, you also enable or disable DAUR. The default for AAUR
is enabled, so DAUR is also enabled by default.
There are no commands to separately enable or disable DAUR.
The log file displays the following messages when DAUR completes successfully:
I 2 00:02:01:20 18 DAUR - Info: Receive request for diag image, start
transfer
I 2 00:02:01:22 19 DAUR - Info: Diag transfer finished
Add a unit to a stack
When you enable AAUR on stack and then add another unit with different software image, this
unit does not join the stack immediately. The unit is now in stand-alone mode.
The new unit sends an AAUR request to the up stream port. If the unit does not receive an
answer, it sends a request to the down stream port. After the image transfers successfully, the
switch reboots.
If you add a unit with the base unit select switch set to off to a unit with base unit select switch
set, the non-base unit gets the diagnostic image from the base unit.
