Installing or Replacing Modules, Fan Trays, and Power Supplies
Unable to create image links for the supervisor-3E module images. The following syslog message is
displayed:
<Tue Apr 30 10:02:47 2019> ERROR!!! Supervisor-3 (N77-SUP3E) image links could
not be created for Standby Supervisor-3 bootup, aborting migration ...
Action to be performed
Use the migrate sup kickstart <sup3-kickstart-image> system <sup3-system-image> command again.
• Problem
After the supervisor-3E module is detected, the arbiter links of the F4-series I/O modules are changed
to 12G as the supervisor-3E module supports a speed of 12G compared to 4G in the supervisor-2E
module. This change has to be done for all F4-series I/O modules present in the switch. In case of failure
in changing to the 12G link for any F4- series I/O module, 3 retry attempts are initiated. After all the
attempts to change the arbiter links fail, ensure that the standby supervisor arbiter link for all F4-series
I/O modules are set to 4G. In case the standby supervisor arbiter link for all F4-series I/O modules are
not set to 4G, the standby supervisor-2E module will not come up if a supervisor-2E module is inserted
instead of the supervisor-3E module after migration failure.
The following syslog messages are displayed in case of failure in changing the standby supervisor arbiter
links for the F4-series I/O modules:
<Tue Apr 30 10:02:47 2019> ERROR!!! Failed to change Standby Supervisor

arbiter link for F4 linecard in slot <F4_linecard_slot> even after 3
retries, aborting migration ...
Action to be performed
