About the AIX Host Utilities 6.1 release

The AIX Host Utilities enable you to connect an AIX host to NetApp storage. The AIX Host Utilities support multiple environments and the FC, FCoE, and iSCSI protocols. The supported environments are AIX MPIO (Native OS) and PowerVM.


For specific information about the operating system versions and updates that the Host Utilities support, see the NetApp Interoperability Matrix Tool.

For more information about PowerVM feature, see the IBM PowerVM Live Partition Mobility Red Book.

The Host Utilities software is packaged as a single, compressed file. You can download the compressed file and the documentation from the NetApp Support Site. The ONTAP SAN Host Configuration provides instructions for installing and setting up the Host Utilities to work with your environment and protocol.

Note You must enable Dynamic Tracking for all FC and FCoE initiators for clustered Data ONTAP deployments.

AIX Host Utilities 6.1 enhancements

  • AIX Host Utilities 6.1 added support for the memory fault issue that occurred in earlier versions of AIX host OS. With AIX Host Utilities 6.1, only the sanlun binary has changed. The MPIO and related ODM remain unchanged.

Fixed Issue

BugID Title Description


sanlun lun show –p command might cause a memory fault on some versions of AIX host OS

Intermittent instances of AIX coredump are reported while running the sanlun lun show -p command. Sanlun’s lun show -p option provides the multipathing information for all the LUNs discovered on a host. It arranges this information to present which SCSI device is sourced from which LUN, the path state (primary or secondary), and other details. However, on some AIX hosts running the sanlun lun show -p command might cause a memory fault. This issue is observed only when you run the sanlun command with the -p option.

Known Problems and Limitations

To use the Host Utilities efficiently, you should be aware that performance can be affected by known issues about a particular feature, such as a network, or by features that the Host Utilities do not support, such as a specific version of an operating system.

Bug ID Title Description


AIX HU Sanlun reports incorrect HBA speed

Instances of sanlun displaying incorrect HBA speeds are reported while running the sanlun fcp show adapter –v command. The sanlun fcp show adapter –v command displays the HBA cards information, such as supported and negotiated speeds for the adapters. This seems to be a reporting issue only. To identify the actual speed, use the fcstat fcsx command.

NetApp Bugs Online provides complete information for most known issues, including suggested workarounds where possible. Some keyword combinations and bug types that you might want to use include the following:

  • FCP General: Displays FC and HBA bugs that are not associated with a specific host.

  • FCP - AIX
