After powering down the supervisor-2E module, the switch will check for the presence of a module in the slot from which the
supervisor-2E module was removed. This check happens every 30 minutes after the supervisor-2E module has been removed. In
case this check to detect the presence of the supervisor module fails, the following syslog message is displayed:

-
Problem
In case the supervisor-3E module is not inserted into the standby slot within 30 minutes after the supervisor 2E module has
been powered down, the following syslog message is displayed:
<Tue Apr 30 10:02:47 2019> ERROR!!! Timeout waiting for Supervisor-3 (N77-SUP3E)

-
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>

Problem
In case the supervisor-3E module is not inserted within 30 minutes after using the migrate sup kickstart <sup3-kickstart-image> system <sup3-system-image> command, the switch will try to power up the powered-down supervisor-2E module in the standby slot on reaching the timeout
of 30 minutes. If the standby supervisor-2E module fails to power up, the following syslog message is displayed before aborting
migration:
<Tue Apr 30 10:02:47 2019> ERROR !!! Failed to power up Standby Supervisor-2,
Please power up manually using "no poweroff module <slot_num>" from config mode
Action to be performed
Use the no poweroff module
<slot-number> command on the active supervisor 2E module to bring up the powered down standby supervisor 2E module in case the supervisor
3E module has not been inserted within 30 minutes after using the migrate sup kickstart <sup3-kickstart-image> system <sup3-system-image> command again.
-
Problem
Once the supervisor-3E module is active after migration has been completed successfully, both the arbiter links of the F4-
series I/O modules will be changed to 12G. After migration, in case the other link to the powered down supervisor-2E module
is not automatically changed to 12G due to an error, the following syslog message is displayed:
Switch %$ VDC-1 %$ %BOOTVAR-2-F4_LC_ARB_LINK_SET_FAIL: ERROR!!! Failed to change
Standby Supervisor arbiter link for F4 linecard in slot <F4_linecard_slot>. Please run
'migrate clean' once migration process gets completed, but before replacing
Supervisor-2 (N77-SUP2E) in standby slot.
Action to be performed
After migration has been completed, use the migrate clean command before replacing the supervisor-2E module in the standby slot.
-
Problem

SUP3E). Please set boot variables manually using 'boot kickstart <kickstart_image>'
and 'boot system <system_image>' and save configs before replacing Standby
Supervisor-2 (N77-SUP2E)
Action to be performed
Use the boot kickstart
<kickstart_image> and the boot system
<system_image> on the active supervisor 3E module when it becomes active after the migration has been completed.
