A Fibre-to-SCSI address conversion
Disks connected with fibre channel display as SCSI disks on UNIX hosts. Disks connected with
fibre channel connections can be fully utilized. RAID Manager converts fibre-channel physical
addresses to SCSI target IDs (TIDs) using a conversion table (see
Figure 9 (page 52) ).
Table 14 (page 52) shows the current limits for SCSI TIDs and LUNs on various operating systems.

If ISCSI, AL_PA is fixed a value 0xFE.
Table 14 Limits for Target IDs and LUNs
Windows Systems Solaris, IRIX Systems HP-UX, other Systems -
LUN TID LUN TID LUN TID Port
0 to 1023 0 to 31 0 to 1023 0 to 125 0 to 1023 0 to 15 Fibre
0 to 7 0 to 15 0 to 7 0 to 15 0 to 7 0 to 15 SCSI
Conversion table for Windows. The conversion table for Windows is based on conversion by an
Emulex driver. If the fibre-channel adapter is different (for example, Qlogic, HP), the target ID that
is indicated by the raidscan command may be different from the target ID on the Windows host.
Example 6 “Using Raidscan to Display TID and LUN for Fibre-Channel Devices” shows an example
of using the raidscan command to display the TID and LUN of Harddisk6 (HP driver). You must
start HORCM without the descriptions of HORCM_DEV or HORCM_INST in the configuration
definition file because of the unknown TIDs and LUNs.
