Hi,

 

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:

https://library.netapp.com/ecm/ecm_download_file/ECMLP2494091

 

Disable any unused SAS ports:

    
SASPortDisable <sas port>
 
Note:If you are configuring an ATTO 7500N bridge then all the SAS ports A through D
are enabled by default. You must disable the SAS ports that are not being used.

 

 

regards, Niels

Niels,

 

I had the ports disabled, but without the restart.

"SaveCondiguration Restart" did the job!

Thx!

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.

Example

If using the CLI, issue the following command:

SaveConfiguration Restart

You are prompted to restart the bridge.

Sorry for causing confusion by just posting the part to disable the ports.

 

regards, Niels

Yep, just disable the ports and the next check, the error is gone!

Martijn,

 

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.

 

Thx.
