Configuring With Scsi-Fc Fabric Router Disk Array Attachment - HP XP1024 Operating System Configuration Manual

Configuring with SCSI-FC fabric router disk array attachment

Installation
Configure disk array devices attached through the SCSI-FC Fabric Router
in the same way as for other SCSI disk devices. No special MPE/iX
configuration steps are required. However, before proceeding read the
guidelines in the "Jazz Router Paper" cited on
Use the MAPPER (or MAPPER2 for A-Class and N-Class) I/O mapping
utility program in the Offline Diagnostic Environment (ODE) to display the
I/O paths for the SCSI HBAs and the disk array devices (targets and
LUNs). Then use either SYSGEN or MPE/iX's IOCONFIG utility
command and the I/O paths reported by MAPPER to perform the MPE/iX
I/O configuration of SCSI HBAs and disk Ldevs.
To configure disk array devices attached by SCSI-FC Fabric Router:
1. Boot the system to the ISL> prompt on the primary boot path.
2. Invoke the ODE (Offline Diagnostic Environment) system from the
ISL> prompt.
3. Run the MAPPER (or MAPPER2 for A- and N-Class systems) I/O
mapping utility within ODE.
Running MAPPER will verify that the disk array devices are
recognized by the host system. MAPPER should "see" and report the
presence of all of the new SCSI HBAs and XP disk array devices.
4. Locate the I/O paths for the SCSI HBAs and disk array devices in the
MAPPER output, and record the paths for later use in SYSGEN or
IOCONFIG.
5. Exit the ODE system back to the ISL> prompt.
6. Start MPE/iX on the primary boot path.
7. Run either SYSGEN or IOCONFIG to perform I/O configuration of the
SCSI HBAs for the disk array devices and the disk array Ldevs.
8. For SYSGEN, after saving the I/O configuration, you must shut down
and restart the OS to put the new configuration into effect. For
IOCONFIG, the new configuration is immediately effective without any
shutdown and reboot.
