Describes how to use IBM AIX 7.2 and/or PowerVM VIOS 3.1 with with ONTAP

Using HP-UX 11i v3 with NetApp ONTAP

Installing the HP-UX Host Utilities

You can download the compressed file containing the Host Utilities software packages from the NetApp Support Site. After you have the file, you must uncompress it to get the software packages you need to install the Host Utilities.

Steps

  1. Download a copy of the compressed file containing the Host Utilities from the NetApp Support Site to a directory on your host.

  2. Go to the directory containing the download.

  3. Uncompress the file.

    gunzip netapp_hpux_host_utilities_6.0_ia_pa.depot.gz

  4. Enter the following command to install the software:

    swinstall -s /netapp_hpux_host_utilities_6.0_ia_pa.depot NetApp_santoolkit

  5. Reboot the host.

SAN Toolkit

Example

In the following example, the sanlun lun show command returns LUN information.

#sanlun lun show

controller(7mode)/                            device                         host     lun
vserver(Cmode)    lun-pathname               filename                       adapter protocol  size  mode

SAN Booting

Before you begin

If you decide to use SAN booting, it must be supported by your configuration. You can use the NetApp Interoperability Matrix Tool to verify that your OS, HBA, HBA firmware and the HBA boot BIOS, and ONTAP version are supported.

SAN booting is the process of setting up a SAN-attached disk (a LUN) as a boot device for a HP-UX host. The Host Utilities support SAN booting with FC and FCoE protocols in HP-UX environments.

Multipathing

Multipathing allows you to configure multiple network paths between the host and storage system. If one path fails, traffic continues on the remaining paths. For a host to have multiple paths to a LUN, multipathing must be enabled. The HP-UX Host Utilities support different multipathing solutions based on your configuration. The following is for the Native Multipathing solution.

# sanlun lun show -p vs39:/vol/vol24_3_0/lun24_0
                    ONTAP Path: vs39:/vol/vol24_3_0/lun24_0
                           LUN: 37

HPUX LVM creation sends I/O of block size above 1MB

SCSI Maximum Transfer Length of 1 MB is enforced in ONTAP All SAN Array. To restrict the Maximum Transfer Length from HP-UX hosts when connected to ONTAP All SAN Array, it is required to set the Maximum I/O size allowed by the HP-UX SCSI subsystem to 1 MB.

Refer HP-UX vendor documentation for details.
