Chapter 2 SCSI Addressing The bridge appears on each SCSI bus as a single initiator. The default initiator ID is 7, but it can be set to any valid SCSI address. No other device on the SCSI bus may use this address. Note that the FC host itself is not connected to the bus. Their SCSI operations are passed down to the individual SCSI Target devices through the use of the bridge's SCSI Initiator ID. The bridge provides the capability to reset SCSI buses during the bridge boot cycle. The feature is enabled in the default configuration, but should be disabled for configurations using multiple SCSI initiators or devices that have long reset cycles or are adversely affected by bus resets. The bridge negotiates for the maximum values for transfer rates and bandwith on a SCSI bus. If an attached SCSI device does not allow the full rates, the bridge will use the best rates it can negotiate for that device. Negotiation is on a device specific basis, so the bridge can support a mix of SCSI device types on the same SCSI bus. Chapter 2 SCSI Addressing 37
