Format of the fc_pcitable file
The /etc/opt/hpcfs/fc_pcitable file contains entries only for the drivers installed on your
system. By default, the entries in the file are commented out, as indicated by the comment character
(#). The file is used only if you add a new entry to the file or modify a default entry (by removing the
comment character and then changing the appropriate values).
Each line in the file contains six fields, as shown in the following example for the default qla2x00
driver:
0x1077 0x2200 qla2x00 scsi "" QLogic 2200 Adapter
The fields contain the following information:
• Vendor ID.
• Device ID.
• Driver name. Do not include .o in the name.
