Setting up your system for multi-path management software For your system to operate with hosts running multi-path management software, two iSCSI IPs are required. These IPs should be on separate physical interfaces on separate SPs. Verify the configuration in Unisphere. For details on how to configure iSCSI interfaces, refer to topics about iSCSI interfaces in the Unisphere online help. NOTE: For highest availability, use two network interfaces on the iSCSI interface. The network interfaces should be on separate subnets. You can view the network interfaces for an iSCSI interface within Unisphere. Installing PowerPath Steps 1. On the host or virtual machine, download the latest PowerPath version from the PowerPath software downloads section on the Online Support website. 2. Install PowerPath as described in the appropriate PowerPath installation and administration guide for the host's or virtual machine's operating system. This guide is available on Online Support. 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. Configuring iSCSI LUNs for the host About this task Use Unisphere or the CLI to: Steps 1. Create storage over iSCSI for the host. 2. Add the host to the storage system in Unisphere or by using the Unity CLI and creating a host. If your host is not already logged in, manually create an iSCSI initiator by providing the host IQN. 3. Provide host access to the storage over iSCSI. Host access options are: No Access, LUN, Snapshot, LUN and Snapshot. NOTE: On a Mac OS host, the Xtend SAN iSCSI initiator will not log into the iSCSI storage if no vdisk0 is configured on the target (iSCSI interface). We recommend that you to create a unique iSCSI interface, create an iSCSI resource on this iSCSI interface, and provide access to the Mac OS host. The first LUN that you create on this iSCSI resource is vdisk0. For information on performing the above Unisphere tasks, refer to the Unisphere online help. Windows host - Setting up for iSCSI LUNs To set up a Windows host for iSCSI LUNs, perform these tasks: 1. Install the Unity VSS HW Provider 2. Install the Microsoft iSCSI Initiator and iSCSI initiator service on the Windows host (Windows Servers) 3. Start the iSCSI initiator service (Windows Servers) 4. For a multi-path configuration, install the MPIO feature (Windows Servers) 5. Set registry values Setting Up a Windows or Mac OS Host to Use LUN storage over iSCSI 31

Setting up your system for multi-path management software
For your system to operate with hosts running multi-path management software, two iSCSI IPs are required. These IPs should
be on separate physical interfaces on separate SPs.
Verify the configuration in Unisphere. For details on how to configure iSCSI interfaces, refer to topics about iSCSI interfaces in
the Unisphere online help.
NOTE:
For highest availability, use two network interfaces on the iSCSI interface. The network interfaces should be on
separate subnets. You can view the network interfaces for an iSCSI interface within Unisphere.
Installing PowerPath
Steps
1.
On the host or virtual machine, download the latest PowerPath version from the PowerPath software downloads section on
the Online Support website.
2.
Install PowerPath as described in the appropriate PowerPath installation and administration guide for the host’s or virtual
machine’s operating system.
This guide is available on Online Support. 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.
Configuring iSCSI LUNs for the host
About this task
Use Unisphere or the CLI to:
Steps
1.
Create storage over iSCSI for the host.
2.
Add the host to the storage system in Unisphere or by using the Unity CLI and creating a host. If your host is not already
logged in, manually create an iSCSI initiator by providing the host IQN.
3.
Provide host access to the storage over iSCSI. Host access options are:
No Access
,
LUN
,
Snapshot
,
LUN and Snapshot
.
NOTE:
On a Mac OS host, the Xtend SAN iSCSI initiator will not log into the iSCSI storage if no vdisk0 is configured
on the target (iSCSI interface). We recommend that you to create a unique iSCSI interface, create an iSCSI resource
on this iSCSI interface, and provide access to the Mac OS host. The first LUN that you create on this iSCSI resource is
vdisk0.
For information on performing the above Unisphere tasks, refer to the Unisphere online help.
Windows host — Setting up for iSCSI LUNs
To set up a Windows host for iSCSI LUNs, perform these tasks:
1.
Install the Unity VSS HW Provider
2.
Install the Microsoft iSCSI Initiator and iSCSI initiator service on the Windows host (Windows Servers)
3.
Start the iSCSI initiator service (Windows Servers)
4.
For a multi-path configuration, install the MPIO feature (Windows Servers)
5.
Set registry values
