Contributors NetAppZacharyWambold

Linux Unified Host Utilities software includes the sanlun utility, a NetApp LUN reporting tool that you can use to display information about storage cluster nodesand Host Bus Adapters (HBAs) that are on the Linux host. You must also enable the correct server profile on the Linux host to optimize NetApp storage performance.

Before you begin

You must have identified the supported Linux Unified Host Utilities version for your configuration by using the Interoperability Matrix. You must also have the tuned package, which is part of your Linux OS distribution and contains the tuned-adm command, which you use to set the server profile on the host.

Steps
  1. Download the supported Linux Unified Host Utilities version from the NetApp Support Site.

  2. Install Linux Unified Host Utilities software by following the instructions in the installation documentation.

  3. If the tuned package is not installed, enter the following command:yum install tuned

  4. For a physical host, ensure that you have set the enterprise-storage profile: tuned-adm profile enterprise-storage

  5. For a virtual host, ensure that you have set the virtual-guest profile: tuned-adm profile virtual-guest
