An HBA is a circuit board installed inside the Controller riser board assembly.
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.
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.
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.
Label all cables connected to the Controller so that they can be reconnected accurately to the Controller after the replacement procedure is complete.
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) |
SAN |
1, 4, 5 |
6 Gb/s SAS PCIe-3, 4x4 port |
ALL |
3, 6, 2 |
16 Gb/s Fibre Channel (FC) or 10GbE iSCSI universal HBA, QLogic | SAN | 1, 4, 5 |
