Checking Disk Shelf Cable Connections (CLI)

Language:

The disk shelf cable checking feature detects such SAS cabling errors as a cable connected to the wrong port on the controller or disk shelf, a missing cable in the redundant path, and a faulty cable. Errors and their resolution can be found in the Active Problems area of the software. Use the following procedure to first check the cable connections on the disk shelf, and then on the controller.

Go to maintenance hardware and select the disk shelf chassis.

hostname:maintenance hardware> select chassis-001
hostname:maintenance chassis-001>

Enter select slot and then enter show.

hostname:maintenance chassis-001> select slot
hostname:maintenance chassis-001 slot> show
Slots:
           LABEL     STATE          MANUFACTURER   MODEL               SERIAL
slot-000   IOM 0     faulted        Oracle         7046837             unknown
slot-001   IOM 1     ok             Oracle         7046837             unknown

Select a slot and enter show to view its properties and components.

hostname:maintenance chassis-001 slot> select slot-000
hostname:maintenance chassis-001 slot-000> show
Properties:
              label = IOM 0
            present = true
            faulted = true
       manufacturer = Oracle
               part = 7046837
             serial = 
             locate = false

Components:
              LABEL               STATE          TERMINAL
port-000      PORT0               connected      1035FMM0GC/PCIe 1/SAS0
port-001      PORT1               unconnected    -
port-002      PORT2               unconnected    -

If the faulted property is true, go to the maintenance problems context and enter show to view the active problems. Note that fixed disk shelf cabling faults are automatically cleared.

(Optional) To view the port properties, select a port and enter show.
The same properties are displayed as in the previous step. The state property shows the connection status. The terminal property displays the device ID, label, and corresponding port on the terminating chassis.
```
hostname:maintenance chassis-001 slot-000> select port
hostname:maintenance chassis-001 slot-000 port> select port-000
hostname:maintenance chassis-001 slot-000 port-000> show
Properties:
              label = PORT0
              state = connected
           terminal = 1035FMM0GC/PCIe 1/SAS0
```
Repeat steps 2 through 4 for each applicable slot.
Enter done until you are at the maintenance hardware prompt.

Select the controller chassis.

hostname:maintenance hardware> select chassis-000
hostname:maintenance chassis-000>

Repeat steps 2 through 5, except choose a SAS HBA slot in step 3.
