SCv2020 alerts: Required connection to peer controller enclosure not found on SAS port

Hi,

found the following alert in my compellent:

Required connection to peer controller enclosure not found on SAS port (WWN=5000D310034AC01B, Slot=2, Port=2)

As side-effect, some of the virtual machines with disks on it were found in read-only filesystem.
What is happening?
