HP-UX vPars and Integrity VM V6.3 Administrator Guide

Example 9 Identifying NPIV HBAs and devices in a vPar
# ioscan -kfNd gvsd
Class I H/W Path Driver S/W State H/W Type Description
ext_bus 0 0/0/0/0 gvsd CLAIMED INTERFACE HPVM AVIO Stor Adapter
ext_bus 1 0/0/4/0 gvsd CLAIMED INTERFACE HPVM NPIV Stor Adapter
ext_bus 4 0/1/3/0 gvsd CLAIMED INTERFACE HPVM NPIV Stor Adapter
NOTE: The ioscan output listing the NPIV devices in the guest is the same as a similar listing
of SAN LUNs in a native host.
Legacy DSFs are not supported for NPIV devices, hence, the ioscan command displays NPIV
devices only if the -N option is used.

7.4.3.8 Configuring multiple paths for NPIV devices
For NPIV devices, multi-pathing products run on the vPar or VM guest and not on the VSP. Multiple
paths to an NPIV device can be configured by presenting it to multiple NPIV HBAs created on
different FC ports on the VSP.
Figure 11 (page 109) shows a possible NPIV configuration that provides multiple paths to the NPIV
device in the guest. In this example, the NPIV disk has 3 paths, one through HBA1 and one each
through each of the two ports on HBA2.
