AIX Host Utilities 6.0 Quick Start Guide
This guide is for experienced AIX users. It provides the basic information required to get the AIX Host Utilities
installed and set up on an AIX host.
The steps listed are for a typical installation and cover multiple AIX environments, including MPIO and
PowerVM . While many steps are common to all environments, some steps apply only to a specific
environment.
If you are not an experienced AIX user, see the AIX Host Utilities Installation and Setup Guide. That document
provides detailed steps and examples. It also includes troubleshooting information as well as instructions for
optional tasks, such as setting up a SAN boot LUN.
For information about installing and setting up third-party hardware and applications, such as host bus
adapters, see the documentation that accompanies those products.
Note: Occasionally there are known problems that can affect your system setup. Read the AIX Host Utilities
Release Notes before you install the Host Utilities. The Release Notes are updated whenever an issue is found
and might contain the information that was discovered after this guide was produced.
Task 1: Make sure the prerequisites for installing and setting up the Host
Utilities have been met
To install the Host Utilities and set up your system, you must perform tasks on both the host and the storage
system. In some cases, the tasks you perform vary depending on your environment; for example, the protocol
you are using and whether you are using AIX MPIO for multipathing.
1. Verify that your host system is correct, including:
• Host operating system version, technology levels, and appropriate updates
• HBAs and drivers, model and version, or software initiator
• Volume management and multipathing, if you are using multipathing
• PowerVM, if you are using PowerVM
The Host Utilities support both PowerVM vSCSI and PowerVM NPIV.
2. Verify that your storage system is set up correctly, which includes having:
• The correct version of Data ONTAP installed.
• The appropriate license for the protocol on which your environment runs.
• Appropriate HBAs or software initiators set up to work with the host as needed by your protocol.
• ALUA enabled on all platforms that support it.
Note: ALUA is the default igroup setting.
For FC environments where ALUA is not supported, the AIX Host Utilities provide the dotpaths utility.
• Working volumes and qtrees (if desired) set up.
3. (FC environments) If you are using a fabric connection, verify that the switch is set up correctly, which
includes having the switch:
• Cabled according to the instructions in the SAN Configuration Guide for your version of Data ONTAP.
• Zoned appropriately, using the supported zoning technique in single initiator zoning from a host's
initiator's standpoint.
• Powered on in the correct order: switch, disk shelves, storage systems, and then the host.
Note: For information about supported topologies, see the SAN Configuration Guide for your version of
Data ONTAP. This guide is available online on
storage/manuals-list.html.
4. (FC direct-attached environment) If you use a direct-attached, FC configuration, set the media type of
the target HBA on the storage system to loop.
Use the fcp config command to stop the HBA, set it to loop (fcp config adapter mediatype
loop), and then restart the adapter.
