When the system is rebooted with FC adapter configured, the software driver for the FC adapter card
initializes the card and identifies FC devices connected to the card. At this time, a message appears on the
system console saying:
td: claimed Tachyon XL2 Fibre Channel Mass Storage card at 0/8/0/0
Scanning for fibre channel devices at 0/8/0/0. This may take a while...
The appearance of this message indicates that the card has been initialized successfully and the software
identified the FC devices connected to this adapter card. To get the list of FC devices connected to the card,
you can run the utility FCSCAN from the MPE/iX CI prompt.
A sample output on running the FCSCAN utility is shown below:
:fcscan
FCSCAN has found the following Fibre Channel I/O Adapter Cards and Devices on this system.

The output from FCSCAN shows the list of FC adapter cards and devices present in the system. The
hardware paths printed by FCSCAN can be directly used in SYSGEN to configure the corresponding device.
The output from FCSCAN utility shows the following information:
• SYSGEN PATH:
— Hardware path of the FC adapter card or device. This is the path, which is to be used in SYSGEN to
configure the card or device in the system.
• DESCRIPTION:
— Description about whether the path specifies a FC card or device. If device, it also specifies the model
and type of the device.
• BOOT MENU PATH:
— Path value for an FC device to be used in the system Boot Command Handler or firmware Main Menu
so as to set that particular device as the primary path. The boot menu path is a detailed long format
path unlike the simplified SYSGEN path. It is necessary to use this long path in boot menu because
the system firmware can understand only this format to access devices. So typically to install on or
boot from an FC disk, the primary path will be set to this long path for that disk as printed by
FCSCAN.
