Processing SCSI Information The following section describes how the bridge processes SCSI information when attached to FC hosts. (See Figure 8 on page 21.) 1. A FC host issues a command. The FC host encapsulates the command in the FC protocol and sends the packet to the bridge. 2.

Chapter 1 Fibre Channel Configurations The bridge is supported in a basic configuration using the 10/180 and 20/ 700 HP tape libraries and magneto-optical jukeboxes. A basic configuration is comprised of only one bridge - HP Surestore Tape Library Model 10/180 | HP Surestore Bridge FC 2/1 LV and FC 4/ - Page 28
Expanded Configuration Figure 12 shows the bridge in an expanded configuration for the FC 2/1 LV. Figure 13 shows the bridge in an expanded configuration for the FC 4/1 HV.

Choosing the Right Configuration The factory default settings of the bridge permit the type of configuration shown in Figure 14 to work without any initial changes to settings in the bridge. The bridge settings may need to be changed for complex configurations or certain application requirements. - HP Surestore Tape Library Model 10/180 | HP Surestore Bridge FC 2/1 LV and FC 4/ - Page 31

either FL_port and F_Port modes with autosensing capabilities. Other switches (such as the HP Surestore Director) only support the F_Port mode. When connecting a bridge directly to a Fibre Channel switch port, configure the bridge in N_Port mode for a more stable and efficient connection. 34 - HP Surestore Tape Library Model 10/180 | HP Surestore Bridge FC 2/1 LV and FC 4/ - Page 33
on the FC loop, as long as there is at least one address available on the loop that is connected to the bridge. Fibre Channel supports up to 126 devices on an arbitrated loop.

device mapping scheme used by that operating system. (Refer to the HBA manual for the mapping table.) The Fibre Channel HBA usually maps Fibre Channel difficulties addressing Target IDs greater than 15 (e.g. 16 and up). This problem can be resolved by configuring the bridge to use hard addressing, - HP Surestore Tape Library Model 10/180 | HP Surestore Bridge FC 2/1 LV and FC 4/ - Page 35
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.

Buffered Tape Writes Buffered Tape Writes is an option designed to enhance system performance. By returning status on consecutive write commands prior to the tape device receiving data, Buffered Tape Writes remove the latency of waiting for responses from the tape device.

Fibre Channel-to-SCSI Mode This section describes the configuration of the bridge when acting as a target to a Fibre Channel initiator passing Fibre Channel protocol (FCP) requests through to SCSI target devices. By default, the bridge is in this mode. The bridge uses hard addressing on the Fibre - HP Surestore Tape Library Model 10/180 | HP Surestore Bridge FC 2/1 LV and FC 4/ - Page 38
Address Mapping The bridge supports three addressing methods for mapping SCSI targets to Fibre Channel initiators (hosts): ■ Indexed Addressing - Allows editing and maintenance of a static address mapping table. ■ Auto Addressing ( - HP Surestore Tape Library Model 10/180 | HP Surestore Bridge FC 2/1 LV and FC 4/ - Page 39
Chapter 2 Indexed Addressing Table 7 Indexed addressing allows for Fibre Channel host bus adapters to access SCSI devices attached to the bridge. This is done by using a table which is indexed by sequential FCP LUN values, indicating selected bus:target:LUN devices. Example of Indexed Addressing - HP Surestore Tape Library Model 10/180 | HP Surestore Bridge FC 2/1 LV and FC 4/ - Page 40
the structure shown in Table 7 on page 41. The bridge will allow up to 80 device entries to be mapped. The index table can be manually edited and is then saved to the bridge FLASH memory. The Configuration menu has options allowing the table to be filled in order of increasing - HP Surestore Tape Library Model 10/180 | HP Surestore Bridge FC 2/1 LV and FC 4/ - Page 41
SCC Addressing The bridge also implements the SCSI-3 controller commands (SCC) (X3T10 Project 1047D Revision 6b 01-July-96) SCSI storage array addressing to address SCSI devices attached to the bridge. The access method used is the SCC logical unit addressing method. In SCC addressing mode, the - HP Surestore Tape Library Model 10/180 | HP Surestore Bridge FC 2/1 LV and FC 4/ - Page 42

Once DHCP is enabled, it is necessary to save the current configuration and reboot the bridge before DHCP will operate. Note For the IP address, Subnet Mask, and IP Gateway address, it is okay to have null values prior to rebooting the bridge.
