HP StorageWorks Disk Array XP operating system configuration guide: MPE/iX (A5951-96145, November, 2005)

Use the MAPPER (or MAPPER2 for A-Class and N-Class) I/O mapping utilit y program in

the Ofﬂine Diagnostic Environment (OD E) 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 attach ed by SCSI-FC Fabric Router:

1. Boot the system to the ISL> prompt on the primary boot path.

2. Invoke the OD E (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 d evices 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 OD E system back to the ISL> prompt.

6. Start MPE/iX on the primary boot path.

7. RuneitherSYSGENorIOCONFIGtoperformI/Oconﬁguration of the SCSI H BAs

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 a ny shutdown and reboot.

9. Use the MPE/iX VOLUTIL utility to create volume sets and volumes on the new

disk array d evices.

A sample I/O conﬁguration p rocedure for disk array devices attached by SCSI-FC

Fabric Router is presented below. For brevity, this example shows only relevant excerpts

fro m the MAPPER listing:

1. Boot on the primary boot path.
