Abstract
A method, system and computer-usable medium are disclosed for providing management of serial attached small computer system interface (SAS) storage devices. A host computer comprises a storage controller connected to a SAS port expander comprising a plurality of ports that are logically assigned to target storage devices. The device ports of all storage devices physically attached to the SAS port expander are bypassed to remove their logical SAS expander port assignments. The storage controller unbypasses the device ports, allowing it to recognize the presence of all physically attached storage devices. The recognized storage devices are inventoried and storage devices that are not logically assigned a SAS expander port are designated as being spare storage devices. SAS expander ports are logically assigned to the non-spare storage devices and SAS storage operations are performed.
