I see the following message when I execute:
=> Cannot complete operation on channel 1c; link is DOWN
The following command:
storage show disk -p
There are some disks without a secundary.
I have made a drawing and this seems a failover fiber loop that doesn't behave as expected.
I have a few questions about this:
1. Why is the system status normal?
2. If I pull this fiber and reseat it, this won't have any impact right?
3. How can I be sure that this is an issue with the fiber and not with the controller?
4. storage show adapter shows:

I tried enabling it but it failed:
delng153> storage enable adapter 1c
Host adapter 1c enable succeeded

Any other thought somebody might have on this?

I figured it out.
Went to the datacenter, an orange led was blinking on the fiber card.
Pulled the cable on both sides. One side the SFP was very loose so I pulled it as well by accident.
After putting it back the issue was gone.
So I am not sure what the cause was. Losely connected cable? Or might it be that the SFP was loose, however then I don't understand why the led was blinking as it just could be that the port was empty.
And in any case... why didn't I see any of that in the logs and is the system status normal?
