OCUM 7.2 P1 reports unused ATTO SAS Port as "Critical Incident".
We have a cDOT MetroCluster with ATTO7500 (4 Stacks/4 SAS-Ports).
Two are in use (1,2 or A,B), two are unused (3,4 or C,D).
Every couple of minutes, OCUM reports the unused SAS-Ports as "offline

this is works as designed and actually not an OCUM issue.
OCUM is just visualizing what the built-in health monitor of ONTAP is reporting.
You will see the same error on ONTAP CLI or System Manager as the system cannot distinguish between a port being unused intentially and a faulty port, e.g. due to a broken cable.
If those ports are indeed not used, they have to be explicitely disabled as described in the Fabric MetroCluster Installation and Configuration Guide - page 148:
Disable any unused SAS ports:

Yep, just disable the ports and the next check, the error is gone!
I had the SAS ports disabled, but the errors kept popping up.
You have to disable the SAS Ports AND do a "SaveConfiguration Restart" on every ATTO to get rid of these errors.
I had the ports disabled, but without the restart.
"SaveCondiguration Restart" did the job!
Hence I posted the link to the configuration guide and the relevant page.
The paragraph just below the one I quoted in my post reads:
Save the bridge's configuration.ExampleIf using the CLI, issue the following command:SaveConfiguration RestartYou are prompted to restart the bridge.
Sorry for causing confusion by just posting the part to disable the ports.
