SAS host – improper connection (miswire)

A host is improperly connected to a drive channel port on one of the storage array's controllers or IOM (ESM).

Important

  • Refer to the cabling documentation for the storage array's controller and drive shelves for more information on valid cabling configurations.

  • To prevent the host from directly accessing the storage array's drives, the port on the controller or IOM that the host is connected to has been disabled.

Recovery Steps​

  1. Disconnect the cable attached to the port listed in the Details area and reconnect it to one of the controller's host ports.

  2. Re-enable the disabled drive channel port.

    1. Go to Support > Support Center. Then, select the Diagnostics tab.

    2. Select the Re-enable Drive Ports link located in the View and/or take action on my current storage array status section.

  3. Select Recheck to ensure the problem has been resolved. If this problem still appears in the Problems area, go to step 4.

  4. Power-cycle ALL of the components involved in the miswire.

  5. Select Recheck to ensure the problem has been resolved.
