Replace a Controller HBA

A failed HBA might cause a Controller failure that could result in the remaining Controllers to shoulder the load. Therefore, if failed, an HBA must be replaced immediately. Additional HBAs can also be added to existing configurations.

Prerequisites:

Ensure that you have a Phillips Number 2 screwdriver with at least a 4-inch shaft.
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.
Keep filler panels available in case you only remove the HBA and do not plan to replace the HBA immediately.

Note: Filler panels ensure proper airflow inside the Controller.
Use only the filler panels provided with the Controller to maintain proper airflow and EMI conformance for empty slots inside the Controller.
Fail over the Controller before replacing the component using Guided Maintenance.

Note: The Controller must be failed over to prevent data loss or data corruption during the component replacement process.
Label all cables connected to the Controller so that they can be reconnected accurately to the Controller after the replacement procedure is complete.

Note: Replacing an HBA might require changes to the port’s world wide name (WWN).

Each Oracle Flash Storage System supports two types of HBA connectivity SAN (FC or iSCSI HBA 16Gb, optical only) and NAS (10 GbE HBA). The placement of the HBA inside the riser slot is based on the Oracle FS System configuration option selected. All HBAs supported in the Oracle FS System are customer replaceable units (CRUs). Replacement of an HBA requires you to bring the Controller offline. HBAs connecting to host servers must be placed into slots 1, 4, and 5 on the risers. HBAs connecting to Drive Enclosures must be placed into slots 2, 3, and 6 on the risers. You must install all HBAs according to the slot numbers listed in the following table.

HBA	System type	Slot number
16 Gb/s Fibre Channel (FC) or 10GbE iSCSI universal HBA, QLogic	SAN	1, 4, 5
10 Gb/s Ethernet dual port or fibre SFP+	NAS	1, 4, 5
6 Gb/s SAS PCIe-3, 4x4 port	ALL	3,6,2

Note: Replacement of the HBA will result in a change to the world wide port name (WWPN) of the HBA

Note: If both Ethernet and FC HBA are used, insert the Ethernet HBA in the first slot of the riser.
