2 Performing Preliminary HP 3PAR Storage System and HostConfiguration

REQUIREDIf you are setting up a fabric along with your installation of the HP 3PAR Storage System, consultSection “Setting Up and Zoning the Fabric” (page 15), before configuring or connecting the storageserver and host.

Configuring the HP 3PAR Storage System Host Persona and Ports (InForm3.1.x)

For an HP 3PAR Storage System running InForm OS 3.1.x and OS 2.3.x, each HP 3PAR StorageSystem port connecting to a host HBA port through a fabric or direct connection must be set to thecorrect host persona.

Configuring Ports for Direct ConnectTo configure HP 3PAR Storage System ports for a direct connection to the host on InForm OS 3.1.xand OS 2.3.x, complete the following steps:1. To set up the HP 3PAR Storage System ports for a direct connection, issue the following set

of commands with the appropriate parameters for each direct connect port:a. controlport offline [node:slot:port]

b. controlport config host –ct loop [node:slot:port]

where -ct loop specifies a direct connection.

c. controlport rst [node:slot:port]

For example:

# controlport offline 1:5:1# controlport config host -ct loop 1:5:1# controlport rst 1:5:1

8 Performing Preliminary HP 3PAR Storage System and Host Configuration

2. After all ports have been configured, verify that the ports are configured for a host in a directconnection by issuing the showport -par command on the HP 3PAR Storage System.In the output below, loop denotes direct connect and point denotes fabric.

Configuring Ports for FabricTo configure ports for Fabric using InForm OS 3.1.x and OS 2.3.x, follow these steps:1. To determine if a port has already been configured for a host port in fabric mode, issue

showport -par on the HP 3PAR Storage System.In the output below, loop denotes direct connect and point denotes fabric.

# showport -par

Configuring the HP 3PAR Storage System Host Persona and Ports (InForm 3.1.x) 9

2. If the port has NOT been configured, take the port offline before configuring it to a host server;issue controlport offline [node:slot:port]. For example:

# controlport offline 0:4:1

3. To configure the port to the host server, issue controlport config host –ct point[node:slot:port] where -ct point indicates that the connection type specified isfabric connect. For example:

# controlport config host –ct point 0:4:1

4. To bring the port online, issue controlport rst [node:slot:port]; for example:

# controlport rst 0:4:1

5. Connect each host HBA port to the fabric. Each host HBA port's worldwide name (WWN)should be associated with the HP 3PAR Storage System port it is connected to.

6. Complete zoning; consult Section “Setting Up and Zoning the Fabric” (page 15).7. Issue showhost to verify that the host has connected to the HP 3PAR Storage System.

Creating the Host Definition (InForm 3.1.x)Before connecting the host to the HP 3PAR Storage System, create a host definition for the Windows2008 host.

NOTE: HP recommends Host persona 1 or 2 for Windows 2008 OS hosts (including iSCSI) toenable Host_Explorer functionality. However, host persona 6 is automatically assigned followinga rolling InForm OS upgrade from version 2.2.x. If appropriate, you can change Host persona 6after an upgrade to host persona 1. Before changing host personas, refer to the HP 3PAR InFormOperating System 3.1.1 Upgrade Pre-Planning Guide for instructions to prevent loss of LUNmapping. Host Persona 1 enables two functional features: Host_Explorer, which requires the SESLunelement of Host persona 1 and the UARepLun, which notifies the host of newly exported VLUNsand should trigger a LUN discovery request on the host, making the VLUN automatically availableon format. However, Windows 2008 does not support this feature, so you must scan LUNs manually.Host persona 2 also enables the RTPG feature, which automatically enables Active/Activemultipathing on Windows 2008 SP1 and SP2 hosts.

• To create host definitions, issue createhost [options] <hostname> [<WWN>...].For example:

# createhost -persona 1 windowshost 10000000C9606724

NOTE: See the HP 3PAR InForm OS CLI Reference or the IMC help for complete details on usingthe controlport, createhost,and showhost commands.

• To verify that the host is created, issue the showhost command; for example:

% showhostId Name Persona -WWN/iSCSI_Name- Port 0 windowshost Generic 10000000C9606724 ---


Configuring the HP 3PAR Storage System Port Personas and Ports (InFormOS 2.2.x)

This section explains these procedures for an HP 3PAR Storage System running InForm OS 2.2.x,in separate subsections:

• Configuring HP 3PAR Storage System ports for direct topology

• Configuring HP 3PAR Storage System ports for fabric topology

• Creating the host definition

Configuring HP 3PAR Storage System Ports for Direct Topology (InForm OS 2.2.x)Follow these steps:1. To set the port persona for each HP 3PAR Storage System port that will connect to an HBA

on the host server, issue controlport persona 1 [node:slot:port].

NOTE: The required port persona value for direct connect is 1.

2. To verify that each port has the correct persona and connection type, issue showport -par.The following is example output:

# showport -par0:4:1 loop auto disable disable (1) g_ven, g_hba, g_os, 0, DC enabled

3. Connect each Host HBA port to its associated HP 3PAR Storage System port. Each host HBAport's worldwide name (WWN) should be associated with the HP 3PAR Storage System portit is connected to.

4. Issue showhost to verify that the host has connected to the HP 3PAR Storage System.

Configuring HP 3PAR Storage System Ports for Fabric Topology (InForm OS 2.2.x)To set up HP 3PAR Storage System ports for fabric connect, complete the following steps for eachfabric connect port.

CAUTION: Do not take ports for fabric connection offline until you verify that the port has notbeen previously defined. A previously defined fabric port might already be connected to hosts.Taking a port offline in this scenario would interrupt the host connection. In cases where the HP 3PARStorage System ports are already configured for fabric, the port will not have to be taken offline.

Follow these steps:

Configuring the HP 3PAR Storage System Port Personas and Ports (InForm OS 2.2.x) 11

1. To determine if a port has already been configured for a host port in fabric mode, issueshowport -par on the HP 3PAR Storage System.In the output below, loop denotes direct connect and point denotes fabric.

# showport -par

N:S:P Connmode ConnType CfgRate MaxRate Class2 UniqNodeWwn VCN IntCoal0:0:1 disk loop auto 2Gbps disabled disabled disabled enabled0:0:2 disk loop auto 2Gbps disabled disabled disabled enabled0:4:1 host point auto 4Gbps disabled disabled disabled enabled0:4:2 host point auto 4Gbps disabled disabled disabled enabled0:5:1 host point auto 2Gbps disabled disabled disabled enabled0:5:2 host loop auto 2Gbps disabled disabled disabled enabled1:0:1 disk loop auto 2Gbps disabled disabled disabled enabled1:0:2 disk loop auto 2Gbps disabled disabled disabled enabled1:2:1 host point auto 2Gbps disabled disabled disabled enabled1:2:2 host loop auto 2Gbps disabled disabled disabled enabled1:4:1 host point auto 2Gbps disabled disabled disabled enabled1:4:2 host point auto 2Gbps disabled disabled disabled enabled1:5:1 host loop auto 4Gbps disabled disabled disabled enabled1:5:2 host loop auto 4Gbps disabled disabled disabled enabled1:5:3 host loop auto 4Gbps disabled disabled disabled enabled1:5:4 host loop auto 4Gbps disabled disabled disabled enabled

2. If the port has NOT been configured, take the port offline before configuring it to a host server;issue controlport offline [node:slot:port]. For example:

# controlport offline 1:5:1

3. To configure the port to the host server, issue:

controlport persona 7 [node:slot:port]controlport vcn disable [node:slot:port]

For example:

# controlport persona 7 1:5:1# controlport vcn disable 1:5:1

NOTE: The required port persona value for fabric is 7. For this port persona value, VCNmust be disabled.

4. To bring the port online, issue controlport rst [node:slot:port]; for example:

# controlport rst 1:5:1

5. Connect each host HBA port to the fabric. Each host HBA port's worldwide name (WWN)should be associated with the HP 3PAR Storage System port it is connected to.

6. Complete zoning; confer Section “Setting Up and Zoning the Fabric” (page 15).

Creating the Host Definition (InForm OS 2.2.x)Before connecting the host to the HP 3PAR Storage System, create a host definition for the Windows2008 host:


1. Issue createhost [options] <hostname> [<WWN>...].For example:

# createhost windowshost 10000000C9606724

2. To verify that the host is created, issue the showhost command; for example:

% showhostId Name WWN/iSCSI_Name------------- Port 0 windowshost 10000000C9606724 ---

Installing the HP 3PAR Host Explorer SoftwareThe HP 3PAR Host Explorer software is recommended for a configuration with a Windows OShost that is connected to HP 3PAR InForm OS.To install the HP 3PAR Host Explorer program, contact your HP account manager or HP CustomerSupport for the CD, and follow instructions in the Host Explorer documentation.

Setting Up MultipathingFor high-availability storage with load balancing of I/O and improved system and applicationperformance, Windows 2008 requires the native Microsoft MPIO and the StorPort miniport driver.Also, a Windows 2008 server connected to an HP 3PAR Storage System running InForm OS 2.2.xrequires the Round Robin MPIO policy.This section explains

• Installing and configuring the native Microsoft MPIO for HP 3PAR storage

• Setting the MPIO policy to round robin for InForm OS 2.2.x

Configuring Microsoft MPIO for HP 3PAR Storage

NOTE: The procedure in this subsection requires rebooting.

Follow these steps:1. If you have not already done so, check HBA vendor documentation for any required support

drivers, and install them.2. If necessary, install the StorPort miniport driver.3. Open the Windows Administrative Tools and click MPIO.4. In the MPIO-ed Devices tab, click the Add button; the Add MPIO Support popup appears.5. In the Device Hardware ID: text box, enter 3PARdataVV, and click OK. See “Adding MPIO

Support for HP 3PAR Devices ” (page 14).

Installing the HP 3PAR Host Explorer Software 13

Figure 1 Adding MPIO Support for HP 3PAR Devices

6. Reboot as directed.

NOTE: You can also use MPIO-cli to add 3PARdataVV. The command is:"mpclaim -r -I -d "3PARdataVV"

Configuring MPIO for Round Robin (InForm OS 2.2.x Only)A Windows 2008 server connected to an InForm Storage Server running InForm OS 2.2.x or laterrequires Round Robin as the MPIO policy. For Windows 2008, the MPIO policy is Round Robinby default. To verify the MPIO policy is default, follow these steps:1. In the Server Manager, click Diagnostics; select Device Manager. Expand the Disk drives list.2. Right-click an HP 3PAR drive to display its Properties window and select the MPIO tab. Select

Round Robin from the drop-down menu. See “Specifying MPIO Policy ” (page 15).


Figure 2 Specifying MPIO Policy

3. Click OK.

Setting Up and Zoning the FabricFabric zoning controls which devices have access to each other on the fabric. The required useof single initiator to single target zoning isolates the host server and HP 3PAR Storage System portsfrom registered state change notifications (RSCNs) that are irrelevant to these ports.You can set up fabric zoning by associating the device World Wide Names (WWNs) or portswith specified zones in the fabric. Although you can use either the WWN or the port zoningmethod with the HP 3PAR Storage System, the WWN zoning method is recommended becausethe zone survives port changes to ports when cables are reconnected on a fabric.Use the methods provided by the switch vendor to create relationships between host server HBAports and storage server ports before you connect the host server HBA ports or HP 3PAR StorageSystem ports to the fabric(s).

REQUIREDWhen you establish zoning with the HP 3PAR Storage System, there must only be a single initiatorzoned with a single target. If a customer experiences an issue using another zoning approach,HP may require the customer to implement this zoning approach as part of troubleshooting and/orcorrective action.After connecting each host server HBA port and HP 3PAR Storage System port to the fabric(s),verify the switch and zone configurations using the InForm CLI showhost command, to ensurethat each initiator is zoned with the correct target.In the following explanations an initiator port (initiator for short) refers to a host server HBA portand a target port (target for short) refers to an HP 3PAR Storage System HBA port.

Setting Up and Zoning the Fabric 15

NOTE: In the examples in the following sections, a fabric can be one or more fibre channelswitches or directors.

Configuring FabricsUse the following fabric vendor guidelines before configuring ports on the fabric(s) to which theHP 3PAR Storage System connects.

• Brocade switch ports that connect to a host server HBA port or to an HP 3PAR Storage Systemport should be set to their default mode. On Brocade 3xxx switches running Brocade firmware3.0.2 or later, verify that each switch port is in the correct mode using the Brocade telnetinterface and the portcfgshow command as follows:

brocade2_1:admin> portcfgshowPorts 0 1 2 3 4 5 6 7-----------------+--+--+--+--+----+--+--+--Speed AN AN AN AN AN AN AN AN Trunk Port ON ON ON ON ON ON ON ON Locked L_Port .. .. .. .. .. .. .. .. Locked G_Port .. .. .. .. .. .. .. .. Disabled E_Port .. .. .. .. .. .. .. .. where AN:AutoNegotiate, ..:OFF, ??:INVALID.

• McData switch or director ports should be in their default modes as type GX-Port with aspeed setting of Negotiate.

• Cisco switch ports that connect to HP 3PAR Storage System ports or host HBA ports shouldbe set to AdminMode = FX and AdminSpeed = auto port, with the speed set to autonegotiate.

• QLogic switch ports should be set to port type GL-port and port speed auto-detect.

CAUTION: QLogic switch ports that connect to the HP 3PAR Storage System should be set toI/O Stream Guard disable or auto but never enable.

Target Port Limits and SpecificationsTo avoid overwhelming a target port and ensure continuous I/O operations, refer to the followinglimitations on a target port:

• Maximum host server ports per HP 3PAR Storage System port: 64

• Maximum total host server ports per HP 3PAR Storage System: 1,024

• I/O queue depth on each HP 3PAR Storage System HBA model as follows:QLogic 2G: 497◦

◦ LSI 2G: 510

◦ Emulex 4G: 959

◦ HP 3PAR HBA 4G: 1638

◦ Emulex 8G: 3276

• The I/O queues are shared among the connected host server HBA ports on a first-come,first-served basis.

• When all queues are in use and a host HBA port tries to initiate I/O, it receives a targetqueue full response from the HP 3PAR Storage System port. This condition can result inerratic I/O performance on each host server. If this condition occurs, each host server should


be throttled so that it cannot overrun the HP 3PAR Storage System port's queues when all hostservers are delivering their maximum number of I/O requests.

NOTE: When host server ports can access multiple targets on fabric zones, the target numberassigned by the host driver for each discovered target can change when the host server is bootedand some targets are not present in the zone. This situation might change the device node accesspoint for devices during a host server reboot. This issue can occur with any fabric-connectedstorage, and is not specific to the HP 3PAR Storage System.

Configuration Diagrams for ZoningThis section describes various zoning configurations.

Single Initiator to Single Target Zoning No Fan-In No Fan-OutFor single initiator to single target zoning in a no fan-in, no fan-out configuration, each HBA portis connected to only one HP 3PAR Storage System port, as shown in “Single Initiator to SingleTarget Zoning No Fan-In/No Fan-Out” (page 17).

Checking the Host Server for Required DriversCheck the Microsoft Web site for required packages and hotfixes, including updated drivers. Alsoconsult the HP 3PAR InForm OS Configuration Matrix for support drivers, and follow HBA vendorinstructions. Use the Emulex HBAnyware or QLogic SANsurfer software to verify support for HBAdriver versions.

Installing and Configuring an Emulex Fibre Channel HBAFor HBA installation instructions, driver support and usage guidelines, refer to the Emulex installationand usage guide for each product type.

NOTE: For booting from the HP 3PAR Storage System, configuring the BIOS is required; “CreatingStorage on the HP 3PAR Storage System” (page 40) has details.

Installing the Emulex Support DriverThe required driver is on the Emulex CD or can be downloaded from the Download section of theEmulex Web site.If your configuration includes MPIO, check also for any required MPIO support driver.

Configuring the Emulex Support DriverAfter installing the driver, set HBA driver parameters; consult the HBA driver documentation fordetails.To avoid overwhelming a target port and to ensure continuous I/O operations, observe thelimitations on a target port; see “Target Port Limits and Specifications” (page 16).

NOTE: When host server ports can access multiple targets on fabric zones, the assigned targetnumber (which is assigned by the host driver) for each discovered target can change when thehost server is booted and some targets are not present in the zone. This situation might changethe device node access point for devices during a host server reboot. This issue can occur withany fabric-connected storage, and is not specific to the HP 3PAR Storage System.

NOTE: If you run InForm OS Rolling Upgrade, consult the HP 3PAR InForm Update Pre-PlanningGuide.To obtain a copy of this documentation, go to http://www.hp.com/go/3par/, navigate to yourproduct page, click HP Support & Drivers, and then click Manuals.

6 Allocating Storage for the Windows 2008 HostCreating Storage on the HP 3PAR Storage System

This section describes the basic method for creating storage. For additional information, see theHP 3PAR InForm OS CLI Administrator’s Manual. For a comprehensive description of HP 3PARInForm CLI commands, see the HP 3PAR InForm OS CLI Reference.

Creating Virtual VolumesYou can create volumes that are provisioned from one or more Common Provisioning Groups(CPGs). Volumes can be fully provisioned from a CPG or can be thinly provisioned. You canoptionally specify a CPG for snapshot space for fully provisioned volumes.Using the InForm Management Console:1. From the Menu bar, select

Actions > Provisioning > VV > Create Virtual Volume2. Use the Create Virtual Volume wizard to create a base volume.3. Select one of the following options from the Provisioning list:

• Fully Provisioned from PDs

• Fully Provisioned from CPG

• Thinly Provisioned

NOTE: To create thin provisioned volumes, an HP 3PAR Thin Provisioning license is required.

Using the InForm CLI:1. To create a fully provisioned or thinly provisioned virtual volume, issue the following InForm

CLI command:

createvv [options] <usr_CPG> <VV_name> [.<index>] <size>[g|G|t|T]

Here is an example:

# createvv -cnt 10 demo 5g

40 Allocating Storage for the Windows 2008 Host

2. Issue showvv to check the volumes created:

NOTE: To create thin provisioned volumes, an HP 3PAR Thin Provisioning license is required.For more information on creating volumes using the InForm OS CLI, see the followingdocuments:• HP 3PAR InForm OS Concepts Guide

• HP 3PAR InForm OS CLI Administrator’s Manual

• HP 3PAR InForm OS CLI Reference

Exporting VLUNs to the Windows 2008 HostFollow the instructions for creating virtual volumes (VVs) and virtual LUNs (VLUNs) in the HP 3PARInForm OS CLI Administrator’s Manual.Note the following guidelines:

• Sparse LUNs are supported (you can skip LUNs).

• You can export LUNs in nonascending order (e.g. 0, 5, 7, 3).

• The Windows 2008 system registers only LUNs 0 to 254.

• The maximum number of usable LUNs per host port is 255. Although the HP 3PAR StorageSystem can export LUNs 0 to 65535, only LUNs 0 to 254 should be used for Windowsconfigurations.

• For an InForm OS previous to OS 2.3.x, the maximum LUN size supported is 2TB; for InFormOS 2.3.1 or later, the maximum LUN size supported is 16TB.

Discovering LUNsUse the Server Manager utility to display formation on the disks: click Storage, and click DiskManagement. “Listing Disk Devices” (page 42) shows an example.

Discovering LUNs 41

Figure 22 Listing Disk Devices

You can also use the HBAnyware or SANsurfer GUI to discover devices. “Listing Disk DevicesSANsurfer GUI” (page 43) shows an example using the SANsurfer GUI.


Figure 23 Listing Disk Devices SANsurfer GUI

Scanning for New Devices on the Windows 2008 HostDisk devices on Windows servers can be used as basic disks or dynamic disks. The HP 3PARStorage System already provides most of the extra capabilities of dynamic disks. HP stronglyrecommends that HP 3PAR Storage System volumes be used only as basic disks unless any of theadditional features of dynamic disks are a requirement.

NOTE: If dynamic disks are used, data corruption can occur if duplicate copies of the samevolume are never concurrently exposed to a server. If you need duplicate copies, use the HP 3PARStorage System Virtual Copy feature, or break a Windows mirrored set of disks created on twodiscrete HP 3PAR Storage System volumes. For dynamic disks with a Windows 2008 server, referto http://technet.microsoft.com/en-us/library/dd163552.aspx.

When VLUNs are exported to the Windows 2008 server, they might not appear in the WindowsDisk Manager automatically. After a new VLUN is exported from an HP 3PAR Storage SystemiSCSI port, issue a rescan from Windows Disk Manager or Windows Device Manager.

NOTE: Be sure that Windows Disk Manager is closed while you are exporting LUNs, and thenwait until the Windows Device Manager shows all of the new LUN exports before you open theWindows Disk Manager. Once all LUNs have been shown as available in the Windows DeviceManager, it is safe to proceed to the Windows Disk Manager to initialize and create disk partitions.

To scan for new devices on the Windows 2008 R2 host, follow these steps:1. In the Windows Server Manager window, click Device Manager.
