HP 3PAR HP-UX Implementation Guide

1) Issue ioscan -kfnNC tgtpath on the HP-UX host.
# ioscan -kfnNC tgtpath
Class I H/W Path Driver S/W State H/W Type Description
======================================================================

2) Issue showport -i on the HP 3PAR StoreServ Storage:
# showport -i

3) To determine the Fibre Channel HBA’s model, hardware path, and the fcd driver
instance, issue ioscan -kfnNC fc:
# ioscan -kfnNC fc
Class I H/W Path Driver S/W State H/W Type Description
==================================================================
fc 5 0/0/4/1/0 fcd CLAIMED INTERFACE HP AB379-60001 4Gb Dual Port PCI/PCI-X Fibre

fc 6 0/0/4/1/1 fcd CLAIMED INTERFACE HP AB379-60001 4Gb Dual Port PCI/PCI-X Fibre
Channel Adapter (FC Port 2)

4) To determine the number of LUN paths for each DSF, issue ioscan -m hwpath:
# ioscan -m hwpath
Lun H/W Path Lunpath H/W Path Legacy H/W Path

0/0/4/1/1.0x21520002ac000036.0x4002000000000000
In the LUN path the 16-bit address following the target port ID
(0x20420002ac000036) represents the LUN number where the device is seen and
the addressing mode. For example, for 0x4001 (which translates to
0100000000000001) the first two bits 01 represents Volume Set Addressing mode
and the remaining 14 bits represent the LUN number, which is LUN 1 in this example.
The host uses estp driver for target paths, eslpt for LUN paths and esdisk as
disk driver.
5) You can find the health of a device, target, LUN path and determine whether it is
on or off line using the -P option. The -C option can be used to specify attributes
