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

Additional Modules Available with HP 3PAR MPIO for AIX
In the event of a failure, the customer support representative requires access to information regarding
the installation and configuration of the AIX or IBM Virtual I/O Server host. To access this
information, use the 3par_explorer.sh utility.
This utility is located in /usr/lpp/3PARmpio/bin.
Installing HP 3PAR ODM for AIX MPIO on the AIX Server (Local Boot Drive)
when Using HP 3PAR OS 3.1.x or OS 2.3.x
This section describes how to install the HP 3PAR ODM for the AIX MPIO.
NOTE: HP 3PAR OS 3.1.x and OS 2.3.x support the HP 3PAR ODM 3.1 for the AIX native
multipathing solution (default path control module (PCM) and the native MPIO framework).
Installing HP 3PAR ODM for AIX MPIO
This procedure applies to either a new installation or an existing installation where HP 3PAR
StoreServ Storage virtual volumes (VVs) already exist on an AIX 7.1, AIX 6.1, AIX 5.3, or IBM
Virtual I/O Server system. This installation must be performed by a user logged into either the AIX
system or IBM Virtual I/O server with root privileges.
NOTE: For the IBM Virtual I/O Server, the commands within this section are performed from the
IBM Virtual I/O Server oem_setup_env environment and start with a #on the command line. To
enter the oem_setup_env environment from the padmin user account, issue the AIX CLI command
oem_setup_env.
Installation of the HP 3PAR ODM requires a system reboot to become effective. SMIT MPIO can
be used to configure or manage the MPIO environment. By default, the AIX MPIO is set to
active/active mode. Install the HP 3PAR ODM software for IBM AIX on either the AIX or the IBM
Virtual I/O server host. If you are using Veritas VxDMP, do not install the HP 3PAR ODM software
for IBM AIX. Instead, install the HP 3PAR ODM software for Veritas VxDMP.
1. Load the distribution CD containing the HP 3PAR ODM for IBM AIX into the CD drive.
2. Issue smit on the AIX CLI to install the HP 3PAR MPIO for IBM AIX from the distribution CD.
If HP 3PAR MPIO has been previously installed, Issue smit update_all on the AIX CLI.
NOTE: Be sure to set the parameter ACCEPT new license agreements to yes.
3. Add the 3par_pathmon.sh to /etc/inittab so that it runs after the AIX host reboots as
in the following example:
# /usr/lpp/3PARmpio/bin/3par_pathmon.sh —a
The 3par_pathmon entry has been added to /etc/inittab
4. Restart the AIX server or IBM Virtual I/O Server.
5. After the server reboots, verify that 3par_pathmon.sh is running as follows:
# /usr/lpp/3PARmpio/bin/3par_pathmon.sh —s
The 3PAR path monitoring program has been started.
For upgrade and removal instructions, see the HP 3PAR ODM 3.1 Software for IBM AIX Readme.
