HP 3PAR AIX and IBM Virtual I/O Server Implementation Guide

Creating the Host Definition
Before connecting the AIX or IBM Virtual I/O Server host to the HP 3PAR StoreServ Storage, create
a host definition that specifies a valid host persona for each HP 3PAR StoreServ Storage that is to
be connected to a host HBA port through a fabric or a direct connection. AIX uses the generic
legacy host persona of 8 for both the QLogic and Emulex HBAs. The following steps show how to
create the host definition.
1. To create host definitions on the HP 3PAR StoreServ Storage, issue the following command:
# createhost [options] <hostname> [<WWN>...]
AIX host example:
# createhost -persona 8 AIXhost 1122334455667788 1122334455667799
IBM Virtual I/O Server example:
# createhost -persona 8 VIOS 1122334455667788 1122334455667799
2. To verify that the host has been created, issue the showhost command.
AIX example:
# showhost
Id Name Persona......-WWN/iSCSI_Name- Port
2 AIXhost AIX-legacy 1122334455667788 4:0:1
1122334455667799 5:0:1
IBM Virtual I/O Server example:
# showhost
Id Name Persona -WWN/iSCSI_Name- Port
6 VIOS AIX-legacy 1122334455667788 ---
1122334455667799 ---
NOTE: When the LUNs are presented to an AIX VIO client using NPIV, the AIX host OS (persona
8) should be used. In the case of LUNs presented to the IBM Virtual I/O Server and then presented
to the AIX client using vSCSI, IBM Virtual I/O Server host OS (persona 8) should be used. Both
AIX and IBM Virtual I/O Server host OS types use persona 8, which means, from a host perspective,
that there is no difference in behavior from the array. The IBM Virtual I/O Server host OS can be
used as an administrative tool to keep track of which LUNs are presented to the IBM Virtual I/O
Server, and which are presented to the AIX VIO clients directly.
NOTE: See the HP 3PAR Command Line Interface Reference or the HP 3PAR Management Console
User’s Guide for complete details on using the controlport, createhost, and showhost
commands.
