Determining Fibre Channel Devices Connected To Fc Adapter - HP e3000 User Manual

The last component in the FC path represents an "FC LUN" while in a SCSI device path it would be a "SCSI
LUN". Although the FC LUN is functionally the same as a SCSI LUN, it is termed differently to signify that
it can take on much larger values.

Determining Fibre Channel Devices Connected to FC Adapter

There is no way in the HP e3000 system firmware Main Menu to identify the FC devices connected to an FC
adapter card. Running ODE MAPPER2 from ISL does help to identify some FC devices but even this may not
list out all the LUNs under the FC devices. For configuring in MPE/iX we ultimately need the FC LUN paths.
In order to assist the System Administrator in identifying the FC devices and LUNs accessible from an FC
adapter card, MPE/iX provides a new utility called FCSCAN. This utility is present in the system as
"FCSCAN.PUB.SYS".
Before using FCSCAN to identify FC devices/LUNs under an FC adapter, you need to make sure that the FC
adapter has been configured in the system. The steps mentioned under the section"Configuring Fibre
Channel Mass Storage Adapter" should have been completed before running FCSCAN utility.
A sample output generated on running the FCSCAN utility is shown below:

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 the 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 an FC card or device. If device, it also specifies the model
and type of the device.
• BOOT MENU PATH:
