Replace a Pilot SAS HBA

A serial attached SCSI (SAS) host bus adapter (HBA) provides access to the SAS hard disk drive (HDD) in the Pilot. A damaged SAS HBA can result in losing access to the SAS HDD to which the SAS HBA connects using the SAS cable bundle and must be replaced as soon as possible.

Prerequisites:

Before handling a component, touch a grounded surface to discharge any static electricity.
Attach an electrostatic discharge (ESD) wrist strap to your wrist, and stand on an ESD mat while replacing components.
Ensure that you have a Phillips Number 2 screwdriver with at least a 4-inch shaft.
Use only the filler panels provided with the Pilot to maintain proper airflow and EMI conformance for empty slots inside the Pilot.
Fail over the Pilot before replacing the component using Guided Maintenance

Note: The Pilot must be failed over to prevent data loss or data corruption during the component replacement process.

Each Pilot supports a single 6 Gb/s SAS HBA on the PCIe slot of its riser. To service a SAS HBA, the PCIe risers inside the Pilot and the filler panels inside the riser must be removed. The SAS HBA is a customer replaceable unit (CRU) and is not hot-serviceable. However, replacing a SAS HBA will require failing over all operations to the other Pilot. The following figure shows the location of the SAS HBA inside a riser board assembly.

Note: The SAS HBA can be accessed only after removing the cover over the Pilot chassis.

Note: To replace a SAS HBA, you do not need to remove the Pilot from the rack but extend it along the Pilot rails using the cable management arm (CMA).

Note: The riser that contains the failed SAS HBA must be removed before servicing the HBA.
