Expected behavior
Software 5.2_non
SSH/SSH
Diagnostic 5.1
Because the diagnostic and agent images are
different, DAUR upgrades the diagnostic
image, and then AAUR transfers the agent.
AAUR and DAUR reboot the unit. The unit joins
the stack after the reboot.
Software 5.2_non
SSH/SSH
Diagnostic 5.2
AAUR performs the agent image transfer and
reboots the unit. The unit joins the stack after
the reboot.
The following logs are provided on the unit transferring the image:
•

transfer

selected).
