Setting Up a Unix Host to Use VNXe Fibre Channel (FC) Storage Using multi-path management software on the host Multi-path management software manages the connections (paths) between the host and the VNXe system should one of the paths fail. The following types of multi-path managements software are available for a host connected to a VNXe system: ◆ EMC PowerPath software on an HP-UX, Linux, or Solaris host ◆ Native mulitpath software on a Citrix XenServer, HP-UX 11i, Linux, or Solaris host Note: PowerPath and AIX Native Multipath (MPIO) software are not currently supported for an AIX host connected to VNXe LUNs. For the supported versions of the PowerPath or native multipath failover software, refer to the VNXe EMC Simple Support Matrix for the VNXe Series on the EMC Online Support website (http://www.emc.com/vnxesupport). To find this matrix on the website, search for "Simple Support Matrix" on the VNXe Support Page. Setting up a VNXe system for multi-path management software For a VNXe system to operate with hosts running multi-path management software, each LUN on the VNXe system should be associated with two paths. Installing PowerPath 1. On the host or virtual machine, download the latest PowerPath version from the PowerPath software downloads section on the EMC Online Support website (http://support.emc.com). 2. Install PowerPath using a Custom installation and the Celerra option, as described in the appropriate PowerPath installation and administration guide for the host's or virtual machine' operating system. This guide is available on the EMC Online Support website. If the host or virtual machine is running the most recent version and a patch exists for this version, install it, as described in the readme file that accompanies the patch. 3. When the installation is complete, reboot the host or virtual machine. 4. When the host or virtual machine is back up, verify that the PowerPath service has started. Installing native multipath software Whether you need to install multipath software, depends on the host's operating system. Citrix XenServer By default XenServer uses the Linux native multipathing (DM-MP) as it multipath handler. This handler is packaged with the Citrix XenServer operating system software. Linux To use Linux native multipath software, you must install the Linux multipath tools package as described in "Installing or updating the Linux multipath tools package" on page 76.

Setting Up a Unix Host to Use VNXe Fibre Channel (FC) Storage
Using multi-path management software on the host
Multi-path management software manages the connections (paths) between the host and
the VNXe system should one of the paths fail. The following types of multi-path
managements software are available for a host connected to a VNXe system:
◆
EMC PowerPath software on an HP-UX, Linux, or Solaris host
◆
Native mulitpath software on a Citrix XenServer, HP-UX 11i, Linux, or Solaris host
Note:
PowerPath and AIX Native Multipath (MPIO) software are not currently supported for
an AIX host connected to VNXe LUNs.
For the supported versions of the PowerPath or native multipath failover software, refer to
the VNXe EMC Simple Support Matrix for the VNXe Series on the EMC Online Support
website (
). To find this matrix on the website, search for
“Simple Support Matrix” on the VNXe Support Page.
Setting up a VNXe system for multi-path management software
For a VNXe system to operate with hosts running multi-path management software, each
LUN on the VNXe system should be associated with two paths.
Installing PowerPath
1.
On the host or virtual machine, download the latest PowerPath version from the
PowerPath software downloads section on the EMC Online Support website
(
).
2.
Install PowerPath using a Custom installation and the Celerra option, as described in
the appropriate PowerPath installation and administration guide for the host’s or
virtual machine’ operating system.
This guide is available on the EMC Online Support website. If the host or virtual
machine is running the most recent version and a patch exists for this version, install
it, as described in the readme file that accompanies the patch.
3.
When the installation is complete, reboot the host or virtual machine.
4.
When the host or virtual machine is back up, verify that the PowerPath service has
started.
Installing native multipath software
Whether you need to install multipath software, depends on the host’s operating system.
Citrix XenServer
By default XenServer uses the Linux native multipathing (DM-MP) as it multipath handler.
This handler is packaged with the Citrix XenServer operating system software.
Linux
To use Linux native multipath software, you must install the Linux multipath tools package
as described in
“Installing or updating the Linux multipath tools package” on page 76
