Verifying Installation
Configuring Fibre Channel Mass Storage Adapter
20
— Path value for an FC device to be used in the system Boot Command Handler or firmware Main Menu
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. 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.
The above sample output shows that there is a Fibre Channel Adapter card configured in the system at path
0/8/0/0. Under this card, there are some devices listed.
Path 0/8/0/0.0 shows an FC N_Port (Node Port) which indicates the fibre channel port of a device connected to
the card. FC N_port is required to be configured in SYSGEN while configuring devices. The output also shows
three disks of type HP OPEN-3 shown with paths 0/8/0/0.0.0, 0/8/0/0.0.1 and 0/8/0/0.0.105. The last
components of these paths refer to the LUN number of these disks. The type HP OPEN-3 usually refers to an
XP512 device disk. Since the hardware paths of these three disks come under Nport 0/8/0/0.0, they all fall
under the same Nport in the XP512 device.
Path 0/8/0/0.95 shows another FC N_Port (Node Port) indicating another device is connected to the card.
Under this N_Port, there are four disk LUNs of type HP A6188A shown with paths 0/8/0/0.95.0, 0/8/0/0.95.5,
0/8/0/0.95.10 and 0/8/0/0.95.50. The type HP A6188A refers to the Virtual Array device A6188A.
FCSCAN utility provides a list of all device N_Ports and LUNs connected to the adapter card. This
information should be used to configure them in SYSGEN. Further details on FCSCAN utility and the steps
for configuring FC device LUNs are covered in the MPE/iX Release 7.5 Communicator document.
NOTE If FCSCAN output shows only the adapter card but no devices under it, then most likely the
device has not been connected properly. Verify the FC cable connecting the FC device to the
adapter. Try again by running FCSCAN with “-h” option. For more details how to run FCSCAN
with this option, refer to the MPE/iX 7.5 Communicator document.
