RAID adapter (HBA) replacement
Use this information to remove and install the HBA on the system board.
A node may be able to self-correct for other adapter card errors, however, a failed HBA can lead to system
degradation and should be quickly addressed.
Note: The ThinkAgile HX2321 contains only one HBA adapter.
