ABSTRACT:
A server is installed with host bus adapters (HBAs). The HBA causes light-emitting components thereon to emit light in abnormal light emission patterns upon falling into an abnormal condition, and in predetermined light emission patterns upon receiving a predetermined command. A method for managing the HBA includes storing abnormal light emission patterns of the HBA, detecting an abnormality as to whether a predetermined HBA is in an abnormal condition, obtaining current light emission patterns of a light-emitting component of an abnormal HBA which is detected to be in the abnormal condition in the detecting, and controlling light emission by sending the predetermined command to all of the HBAs except the abnormal one to cause the light-emitting components thereof to emit light in the predetermined light emission patterns, when the current light emission patterns, obtained in the obtaining, do not match the abnormal light emission patterns stored in the storing.
