The NetApp Host Utilities are software packages for various operating systems that contain management utilities such as the sanlun CLI binary, multipath drivers, and other important files required for proper SAN operations.

Tip

NetApp recommends installing the NetApp Host Utilities on hosts that are connected to and accessing NetApp storage systems. For more information, see Interoperability Matrix Tool and SAN Hosts documentation.
Note With AIX, it is especially critical that the Host Utilities are installed before discovering LUNs. This ensures that the LUN multipathing behavior is configured correctly. If discovery was performed without the Host Utilities, the LUNs will need to be deconfigured from the system using the rmdev -dl command and then rediscovered via cfgmgr or a reboot.
