Removing A Failed Unit; Verifying The New Unit Software Version; Obtaining The Correct Software Version - Avaya Virtual Services Platform 7000 Series Troubleshooting Manual

Important:
If the stack is only two switches, the remaining switch enters Stack Forced Mode if that feature
is enabled.
Important:
For AUR to function properly, the new unit and the existing units in the stack must all run at
least Release 10.1 agent and diagnostic software versions. Agent Auto Unit Replacement
(AAUR) and Diagnostic Auto Unit Replacement (DAUR) are AUR enhancements to ensure that
all units in a stack run the same software images.
For more information about Stack Forced Mode, AAUR and DAUR, see Getting Started with Avaya
Virtual Services Platform 7000 Series, NN47202–303.

Removing a failed unit

Remove the failed unit from the stack.
1. Maintain power to the operating units.
Important:
Do not power down the stack.
2. Disconnect and remove the failed unit.

Verifying the new unit software version

Verify that the new unit to be inserted in the stack has at least software Release 10.1 installed.
1. Connect the new device to the console, independent of stack connection.
2. Use the show sys-info command view the software version.
Note:
If AUR and AAUR is enabled, the new unit is automatically checked and can automatically
update the agent and diagnostic software to match the stack software.

Obtaining the correct software version

If AAUR is not enabled, you can obtain and install the correct software version manually.
Caution:
Ensure you have adequate backup of your configuration prior to reloading software. Know the
Release number of your software before loading it. Loading incorrect software versions can
cause further complications.
