3650 switch stack member remove failure

[Vyacheslav_Maliev]

Hi! We had 5 member 3650 stack. I removed #4 and reconnect #3 to #5 and #5 been hang (all ports off, no management). After rebooting #5 it fall to status "syncing" and then "removed".  So for now i have this situation:

*1 Active 5897.bdab.6780 1 V02 Ready
2 Standby 5897.bde0.ac80 1 V02 Ready
3 Member 5c83.8f00.2700 1 V02 Ready
4 Member 0000.0000.0000 0 0 Unprovisioned
5 Member 0000.0000.0000 0 0 Removed

and logs:

.Mar 21 22:44:15: %SPI_FC-3-HIGH_WMARK_REACHED: Number of messages in the queue for channel 11 has reached maximum.

Please help how to join it back?

Hi,

Traceback messages are usually a sign of software crash. Can you try to un-provision both member 4 and 5 and then re-provision 5 again? After making these changes, you may have to reboot the stack for it to take effect.

no switch 4 provision

no switch 5 provision

switch 5 provision <switch model>

The error message and traceback is a wireless issue (so it has nothing to do with the switch stacking).  Exactly what are you trying to accomplish?

The goal was to remove member #4 from the stack and reconnect member #5 to #3 bypassing #4. But it didnt go well. So for now i have losted #5 and errors on the main stack.
