Logical Drives degraded due to the loss of a redundant path. What is wrong

hp-prolianthp-smart-arrayhp-storageworkssas

HP p822 (four external minisas ports) to pair of d2700s Storage Enclosures. Two ports on the p822 are unused.

The partitioning is not at all identical. The top box has four different logical drives and the bottom box is one single drive for backups.

i have the minisas cables arranged in the following "Dual domain example — best fault tolerance cabling" pattern from page 48 of :enter image description here
![HP StorageWorks
D2600/D2700 Disk Enclosure User Guide page ]2

Upon bootup and initialization of the p822, i get an error that may implicate the path from Port 3E of the p822:

1738-Slot 2 Drive Array Storage Enclosure Redundant Cabling Problem Detected    
    Check storage box I/O module and cable to restore redundant paths to the following disk drive(s):    
    Port 3E: Box 1: Bays 1-25
    Port 3E: Box 2: Bays 1-25

But BIOS level ACU throws warnings that "* 799 Logical Drive X is degraded due to the loss of a redundant path*."

Do you check cabling? I experience problems with some mini-SAS cables. Sometimes, you must pull the blue trip/tab before you can correctly push the connector.
