Abstract
A peripheral coupled to a SCSI bus is isolated using a SCAM isolation step and the original SCSI identification bits (32 bytes) are read from the isolated peripheral into a host adapter. The host adapter then generates a relatively small number (for example, 4 bytes) of identification bits from the relatively large number of original SCSI identification bits. The small number of SCSI identification bits is stored in a non-volatile memory of the host adapter such that the memory location of the SCSI identification bits of a particular peripheral corresponds with the logical system identifier of that peripheral. Even if peripherals are removed from the bus and/or added to the bus, the small number of SCSI identification bits for a peripheral previously on the bus is redetermined and located in non-volatile memory of the host adapter so that the logical system identifier of the peripheral previously coupled to the bus is not changed.
