32 HP StorageWorks Disk Array XP Operating System Configuration Guide: MPE/iX
Follow the procedure below that applies to your system:

Configuring with native Fibre Channel disk array attachment
For native Fibre Channel attachment of disk arrays, MPE/iX Release 7.5
provides the new fcscan utility which is capable of determining the I/O
paths (both in SYSGEN and in PDC formats) for the disk arrays. Before
fcscan can do this, the I/O paths of the Fibre Channel HBAs must first be
configured in MPE/iX, using either SYSGEN or IOCONFIG.
This is the overall procedure for configuring disk arrays with Fibre Channel
attachment:
• Boot and start the system.
• Use SYSGEN or IOCONFIG to configure the I/O paths of the Fibre
Channel HBAs. (Your recorded these I/O paths when you installed
the HBAs into the system.)
•Use fcscan -h to determine the I/O paths for the disk arrays’ N-ports
and LUNs. Using fcscan also verifies disk array device recognition.
• Use SYSGEN or IOCONFIG to I/O configure the disk arrays’
N-ports and LUNs.
After completing the I/O configuration procedure, create MPE/iX volume
sets and disk volumes on the configured XP disk array devices.
The following sample I/O configuration procedure uses IOCONFIG to
perform immediate I/O configuration and fcscan –h to determine device
paths for native Fibre Channel attachment of XP disk arrays. In this
example there are two XP disk arrays, each routed through a SAN FC
switch, and then each attached to an A6795A Fibre Channel HBA on the
server host. The procedure begins after the system has been booted and
started, and for brevity only two LUNs within each XP disk array are
shown being configured by IOCONFIG.
