HP 3PAR Windows 2012 and Windows Server 2008 Implementation Guide

5 Setting Up a Windows Server 2012 or 2008/HP 3PAR
StoreServ Storage Configuration with iSCSI Storage
The HP 3PAR StoreServ Storage supports Windows Server 2012 and Windows Server 2008
software iSCSI initiators, which are described in this chapter.
In addition, as of HP 3PAR OS 3.1.2.x, the HP 3PAR StoreServ 7000 Storage and HP 3PAR
StoreServ 10000 Storage introduce support for hardware iSCSI with supported Converged Network
Adapters (CNAs). For more information about supported configurations, see the HP SPOCK website:
HP SPOCK
To configure supported CNAs, see vendor-specific documentation.
NOTE: HP recommends that you read the Microsoft iSCSI Software Initiator Users Guide for
Windows-specific concepts and procedures discussed in this chapter.
Setting Up the iSCSI Initiator and iSCSI Target Ports
Connect the host iSCSI initiator port(s) and the and the HP 3PAR StoreServ Storage iSCSI target
ports to the switches.
If you are using VLANs, make sure that the switch ports which connect to the HP 3PAR StoreServ
Storage iSCSI target ports and iSCSI Initiator ports reside in the same VLANs and/or that you can
route the iSCSI traffic between the iSCSI Initiator ports and the HP 3PAR StoreServ Storage iSCSI
target ports. Once the iSCSI Initiator and HP 3PAR StoreServ Storage iSCSI target ports are
configured and connected to the switch, you can use the ping command on the iSCSI Initiator
host to make sure that it sees the HP 3PAR StoreServ Storage iSCSI target ports.
WARNING! On Windows Server 2008/2012 servers connected to HP 3PAR F200/F400 or
T400/T800 1Gb iSCSI targets, to reduce MPIO failover times, HP requires that MPIO Path Verify
is enabled.
Follow these steps to enable Path Verify for Microsoft MPIO: -
1. In a command shell or PowerShell window, run the regedit command.
2. In the registry editor window, navigate to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\mpio\Parameters
3. Set the values of UseCustomPathRecoveryInterval to 1 and PathVerifyEnabled
to 1.
4. Reboot the host for the setting to take effect.
NOTE: Switch VLAN configuration and routing setup and configuration are beyond the scope
of this document. Consult your switch manufacturer's guide for instructions about setting up VLANs
and routing.
Configuring the HP 3PAR StoreServ Storage for iSCSI
Follow these steps to set up the HP 3PAR StoreServ Storage for iSCSI storage:
1. (This step applies to the HP 3PAR StoreServ 10000 Storage and the HP 3PAR StoreServ 7000
Storage.) If the HP 3PAR StoreServ Storage iSCSI ports have not been configured for iSCSI,
first use this command:
# controlport config iscsi -f N:S:P
