Reboot the MCR.
Run "airmatch runnow full".
A solution should be generated after a time.
If that doesn't work, open a case with TAC as you've got some sort of issue going on.

If I issue this command on MM, see nothing.

Are you using AirMatch?
From the MM you can use the "show airmatch solution ap-name" - as well as other optimization commands - to get additional details.

I started investigating a problem in Aruba system (many adjacent AP use the same 5GHz channel) and noticed an interesting thing about the ARM statistics. By issuing the "show ap arm rf-summary ap-name" command for each AP, I see that the "Last Check Channel/pwr" and "Last Change Channel/pwr" are almost equal to the AP uptime. Using the "show ap arm history ap-name" command, the history was empty for each AP I checked.
Is this normal? I don't think this is how it should work. What could be the problem, what can I check? In ARM settings everything is on default.
