The storage subsystem contains an improper connection between two Serial Attached SCSI (SAS) ports. The Recovery Guru Details area provides specific information you will need as you follow the Recovery Steps.

Host Adapter Miswire - This miswire condition occurs when you connect an external Host Adapter port to any port other than a Host Channel port (Drive Channel port, ESM In port, or ESM Out port). You should only connect a Host Adapter port to a Host Channel port on a controller.
Important: If a Host Adapter Miswire is reported, the port on the controller or ESM that is connected to the HBA will not be able to connect to any device until after the cabling is corrected and the controller or ESM is power-cycled.

1 | Use the information provided in the Recovery Guru Details area to determine which port is the origin of the miswire. Using this information, trace the cable that is attached to the miswired channel or port to the connector on the other end. | ||||||||||||||||||||||||||||
2 | Refer to your cabling documentation to reconnect the cable to the appropriate port. It may be necessary for you to reconnect more than one cable in order to have a valid configuration.
Once you have a valid cabling configuration, go to step 3. |

5 | Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your technical support representative. | ||||||||||||||||||||||||||||
6 | If you stopped I/O to the storage subsystem in step 4, resume I/O. |
