NetApp and VMware vSphere Storage Best Practices

7 THE NETAPP ESX HOST UTILITIES
NetApp provides the ESX Host Utilities or EHU for simplifying the management of ESX nodes running on
NetApp storage arrays. With the EHU customers receive a collection of tools to automate and simplify the
configuration of HBAs, sets optimized ESX/ESXi options for NFS, enhances Guest OS (VM) SCSI settings,
and provides diagnostic utilities should a support case be opened.
The ESX Host Utilities installs on ESX 4.0 systems, and currently is not supported for ESXi 4.0 systems.
The ESX Host Utilities can be downloaded from NOW (NetApp on the Web).
7.1 INSTALLING THE EHU IN ESX
EHU PREREQUISITES
• FC (which includes FCoE), iSCSI, or NFS is licensed on the storage system.
• You have root access to each ESX Server.
• All storage systems have DNS-resolvable names.
• SSL is set up on every storage controller before installing the Host Utilities if you plan to use SSL to
securely communicate with the controller.
• If you do not want to enter a user name or password when running the Host Utilities, it is
recommended that you enable options httpd.admin.hostsequiv on each controller (option
httpd.admin.hostsequiv.enable on) and that all VMware ESX host names are added to the
/etc/hosts.equiv file on each controller. This will prevent connection problems between the
controllers and the hosts.

To install the ESX Host Utilities complete the following steps:
1 Download the EHU.
2 Copy the EHU to a location accessible to the ESX
