Hi community,
We have a Catalyst 9300 running IOS-XE 16.6.8. Long before that it was at some point running IOS-XE 16.6.3 with two SMU patches. Updates of the software were always done with the install add file ... command.
When the switch boots it tries to load those two old SMU files which are of course no longer on the flash. It displays an error message like : %BOOT-3-BOOTTIME_SMU_MISSING_DETECTED : SMU file [chars] missing and system impact will be unknown.
It boots without problems after that.
Today we tried to add a second switch to form a stack but this fails because of those missing SMU files. The active switch tries to copy the SMU files to the second switch which of course fails because they are not available. The second switch is then marked as incompatible and the state is "V-Mismatch".
Is there a way to remove any references to those old, unnecessary SMU files so that the active switch does not try to load them at boot and I can form the stack successfully?
Any tips much appreciated!
