x440 stack enable sharing issue

[Chingis_Taltae1]

I have an issue with LAG across stack (4x Summit x440-24t-10G stacked via SummitStack-V):

Slot-3 Stack.18 # sh slot

The stack seems to be OK, all nodes are online and operational, XOS version 15.5.4.2 on all nodes.

I need to create 8 ports LAG (LACP enabled) across stack (SFP ports 23-24 on each stack node), but something goes wrong:

Slot-3 Stack.21 # enable sharing 1:23 grouping 1:23-24,2:23-24,3:23-24,4:23-24 lacp
Error: No valid port(s) in the specified "portList" value "1:23-24,2:23-24,3:23-24,4:23-24".
Configuration failed on backup Node, command execution aborted!

I tried to create 2 ports static LAG across stack (for example copper Ethernet 1:1,2:1 with 1:1 as master port), but got similar issue:

Slot-3 Stack.22 # enable sharing 1:1 grouping 1:1,2:1
Error: No valid port(s) in the specified "portList" value "1:1,2:1".
Configuration failed on backup Node, command execution aborted!

I rebooted only switch at stack slot 2 and finally LAG was successfully built:

Slot-3 Stack.3 # reboot slot 2
Do you want to save configuration changes to currently selected configuration
file (primary.cfg) and reboot?
(y - save and reboot, n - reboot without save, - cancel command) Yes
Saving configuration on master ........................ done!
Synchronizing configuration to backup .......... done!
Saving configuration on Standbys (Slots: 2,4).

Finally, everything working as i expected, but i don't i understand - is it bug
or just sync master/backup master with standby nodes issue ?

I will update firmware to the current level further.

Thanks a lot !

From the outputs that you have provided below, it seems like only slot 2 is affected. I would suggest rebooting slot 2 first and check if that helps!

Also, since it is not in production, use the latest recommended image 15.6.3.1 patch 1-5 when you are provisioning this to the production environment. Let us know if reboot solves this!

It is not in production, i'lll try to reboot it later.

Can you send the "show stacking" command along with "debug epm show peer"? Also take a look at the "show port no-refresh" output to see if these ports are present.
