Hi,
our system with two 9800-40 (version 17.03.05b) is no longer redundant and brings the error message:
%BOOT-3-BOOTTIME_GET_ISSU_INFO_OF_REMOTE_CHASSIS_FAILED: Chassis 1 R0/0: issu_stack: Failed to get ISSU information from remote chassis. Details: Remote sync failed with error code: 10.
but I can't find any further information about it. What could be the reason for this?
Thanks !
Dieter

Someone attempted, unsuccessfully, to upgrade the firmware using ISSU.

- Most likely a bug similar too : https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvz31188 , have a try with 17.9.3
(Appendix1) , this is not directly related but useful :
- Have a checkup of the current controller configuration (active) controller with the CLI command show tech wireless ; feed the output into : https://cway.cisco.com/wireless-config-analyzer/

You might need to break SSO - get the software in sync on both and then re-form SSO to get this fixed.
I reckon Leo's suggestion is a good bet, but like Marce says - get off 17.3 and upgrade to 17.9.3 - so many fixes and HA enhancements since 17.3.
