Abstract

Provided are techniques for detecting a type of storage adapter connected to an Input/Output (I/O) bay and miscabling of a microbay housing the storage adapter. Under control of an Input/Ouput (I/O) bay, cable sidebands are driven high for a predetermined period of time. It is determined whether a cable sidebands response has been detected that indicates that the cable sidebands have been driven low. In response to determining that the cable sidebands response has been detected, it is determined that the I/O bay is connected to a first storage adapter supporting a first protocol for the cable sidebands. In response to determining that the cable sidebands response has not been detected, it is determined that the I/O bay is connected to a second storage adapter supporting a second protocol for the cable sidebands. Moreover, I/O bay and port numbers stored by the microbay are used to determine miscabling.
