2 Configuring the HP 3PAR Storage System for Fibre

Channel

This chapter describes how to establish a connection between an HP 3PAR Storage System and HP-UX host using Fibre Channel and how to set up the fabric when running InForm OS 3.1.x, OS

2.3.x, or OS 2.2.x. For information on setting up the physical connection for a particular HP 3PAR Storage System, see the appropriate HP 3PAR installation manual.

REQUIRED

If you are setting up a fabric along with your installation of the HP 3PAR Storage System, consult

“Setting Up and Zoning the Fabric” (page 9) before configuring or connecting your HP 3PAR

Storage System.

Configuring the HP 3PAR Storage System Running InForm OS 3.1.x and OS 2.3.x

This section describes how to configure the HP 3PAR Storage System running InForm OS 3.1.x and OS 2.3.x.

REQUIRED

The following setup must be completed before connecting the HP 3PAR Storage System port to a device.

Configuring Ports for a Direct Connection

To configure HP 3PAR Storage System ports for a direct connection to the HP-UX host, 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] Example:

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

2. After all ports have been configured, verify that the ports are configured for a host in a direct connection by issuing the showport -par command on the HP 3PAR Storage System.

# showport -par N:S:P Connmode ConnType CfgRate MaxRate Class2 UniqNodeWwn VCN IntCoal ... 1:5:1 host loop auto 4Gbps disabled disabled disabled enabled ...

Page 7

Configuring Ports for a Fabric Connection

To configure HP 3PAR Storage System ports for a fabric connection, complete the following steps for each port connecting to a fabric.

CAUTION: Before taking a port offline in preparation for a fabric connection, you should verify

that the port has not been previously defined and that it is not already connected to a host as this would interrupt the existing host connection. If an HP 3PAR Storage System port is already configured for a fabric connection, you can ignore Step 2 as you do not have to take the port offline.

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.

# showport -par N:S:P Connmode ConnType CfgRate MaxRate Class2 UniqNodeWwn VCN IntCoal ... 1:5:1 host point auto 4Gbps disabled disabled disabled enabled ...

2. If the port has NOT been configured, take the port offline before configuring it for connection to a host server. To take the port offline, issue the InForm CLI command controlport

offline [node:slot:port].

# controlport offline 1:5:1

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

is a fabric connection.

# controlport config host –ct point 1:5:1

4. Reset the port by issuing the controlport rst [node:slot:port] command.

# controlport rst 1:5:1

Creating the Host Definition

Before connecting the HP-UX host to the HP 3PAR Storage System, create a host definition that specifies a valid host persona for each HP 3PAR Storage System that is to be connected to a host HBA port through a fabric or a direct connection.

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

# createhost -persona 7 hpux-host 1122334455667788 1122334455667799

Configuring the HP 3PAR Storage System Running InForm OS 3.1.x and OS 2.3.x 7

Page 8

2. To verify that the host has been created, issue the showhost command.

# showhost Id Name Persona -WWN/iSCSI_Name- Port ... 2 hpux-host HPUX-legacy 1122334455667788 -- 1122334455667799 ---

Configuring the HP 3PAR Storage System Running InForm OS 2.2.x

This section describes how to configure the HP 3PAR Storage System running InForm OS 2.2.x.

REQUIRED

The following setup must be completed before connecting the HP 3PAR Storage System port to a device.

Configuring Ports for a Direct Connection

To configure the HP 3PAR Storage System ports for a direct connection, complete the following steps.

1. Set each HP 3PAR Storage System port to port personality 5 by issuing controlport

persona 5 <X:X:X>, where <X:X:X> is the port location, expressed as node:slot:port.

# controlport persona 5 1:2:1

2. Verify that each port has the appropriate personality defined:

# showport -par N:S:P ConnType CfgRate MaxRate Class2 VCN ------------Persona------------ IntCoal ... 1:2:1 loop auto 2Gbps disable disabled (5) aglt, g_hba, hp, 0, DC enabled ...

NOTE: When deploying your storage server in a direct connection, the HP Tachyon HBA

WWN does not show up.

Configuring Ports for a Fabric Connection

To configure the HP 3PAR Storage System ports for a fabric connection, complete the following steps.

1. Set each storage server port that will connect to a fabric to port persona 8 by issuing controlport persona 8 <X:X:X>, where <X:X:X> is the port location, expressed as node:slot:port.

8 Configuring the HP 3PAR Storage System for Fibre Channel

Page 9

2. Issue controlport vcn disable -f <X:X:X> for each port. Verify that each port has the appropriate persona defined:

# controlport persona 8 1:2:1

# showport -par N:S:P ConnType CfgRate MaxRate Class2 VCN -----------Persona-----------IntCoal ... 1:2:1 point auto 2Gbps disable enabled (8) aglt, g_hba, hp, 0, FA enabled ...

Creating the Host Definition

Before connecting the HP-UX host to the HP 3PAR Storage System, create a host definition that is to be connected to a host HBA port through a fabric or a direct connection.

To create host definitions on the HP 3PAR Storage System, issue createhost

[options]<hostname> [<WWN>].

# createhost hpux-host 1122334455667788 1122334455667799

• To verify the host definition, issue showhost:

# showhost Id Name -WWN/iSCSI_Name- Port ... 2 hpux-host 1122334455667788 -- 1122334455667799 ---

Connecting the HP 3PAR Storage System to the Host

During this stage connect the HP 3PAR Storage System to the host server directly or to the fabric. This set of tasks includes physically cabling the HP 3PAR Storage System to the host server or fabric.

Setting Up and Zoning the Fabric

Fabric zoning controls which devices have access to each other on the fabric. The required use of single initiator to single target zoning isolates the host server and HP 3PAR Storage System ports from 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 ports with specified zones in the fabric. Although you can use either the WWN or the port zoning methods with the HP 3PAR Storage System, the WWN zoning method is recommended because the zone survives the changes of ports when cables are reconnected on a fabric.

Use the methods provided by the switch vendor to create relationships between host server HBA ports and storage server ports before you connect the host server HBA ports or HP 3PAR Storage System ports to the fabric.

REQUIRED

When you establish zoning with the HP 3PAR Storage System, there must only be a single initiator zoned with a single target. If an issue occurs using another zoning approach, HP may require that you implement this zoning approach as part of troubleshooting and/or corrective action.

Connecting the HP 3PAR Storage System to the Host 9

Page 10

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 ensure that each initiator is zoned with the correct target.

In the following explanations an initiator port (initiator for short) refers to a host server HBA port and a target port (target for short) refers to an HP 3PAR Storage System HBA port.

Configuration Guidelines for Fabric Vendors

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

• Brocade switch ports that connect to a host server HBA port or to an HP 3PAR Storage System

port should be set to their default mode. On Brocade 3xxx switches running Brocade firmware

3.0.2 or later, verify that each switch port is in the correct mode using the Brocade telnet interface and the portcfgshow command as follows:

brocade2_1:admin> portcfgshow Ports 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 a speed

setting of Negotiate.

• Cisco switch ports that connect to HP 3PAR Storage System ports or host HBA ports should

be set to AdminMode = FXand AdminSpeed = auto port, with the speed set to auto negotiate.

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

• QLogic switch ports that connect to the HP 3PAR Storage System should be set to I/O Stream

Guard disable or auto, but never enable.

Target Port Limits and Specifications

To avoid overwhelming a target port and ensure continuous I/O operations, refer to the following limitations on a target port:

• Maximum of 64 host server ports per HP 3PAR Storage System port, with a maximum total of

1,024 host server ports per HP 3PAR Storage System.

• I/O queue depth on each InServ Storage Server HBA model as follows:

QLogic 2G: 497◦ ◦ LSI 2G: 510 ◦ Emulex 4G: 959 ◦ HP 3PAR HBA 4G: 1638 ◦ HP 3PAR HBA 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 target queue

full response from the HP 3PAR Storage System port. This condition can result in erratic I/O performance on each host server. If this condition occurs, each host server should be throttled

10 Configuring the HP 3PAR Storage System for Fibre Channel

Page 11

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

NOTE: When host server ports can access multiple targets on fabric zones, the assigned target

number assigned by the host driver for each discovered target can change when the host server is booted and some targets are not present in the zone. This situation may change the device node access point for devices during a host server reboot. This issue can occur with any fabric-connected storage, and is not specific to the HP 3PAR Storage System.

Configuration Diagrams for Zoning

This section describes various zoning configurations.

NOTE: In the examples in the following sections, a fabric can be one or more Fibre Channel

switches or directors.

Single Initiator to Single Target Zoning No Fan-In No Fan-Out

With a single initiator to single target zoning, in a no fan-in, no fan-out configuration, each HBA port is connected to only one HP 3PAR Storage System port, as shown in Figure 1 (page 11).

Figure 1 Single Initiator to Single Target Zoning No Fan-In/No Fan-Out

Single Initiator to Single Target Zoning with Fan-Out from One HP 3PAR Storage System Port to Multiple Host Server Ports

With single initiator to single target zoning, in a fan-out configuration, the HP 3PAR Storage System port is connected to more that one host port, as shown in Figure 2 (page 12).

Setting Up and Zoning the Fabric 11

Page 12

Figure 2 Single Initiator to Single Target Zoning with Fan-Out

NOTE: A maximum of 64 host server ports can fan-out from a single HP 3PAR Storage System

port.

Single Initiator to Single Target Zoning with Fan-In from Multiple HP 3PAR Storage System Ports to One Host Server Port

With single initiator to single target zoning, in a fan-in configuration a host server port connects to many HP 3PAR Storage System ports, as shown in Figure 3 (page 12).

Figure 3 Single Initiator to Single Host Target Zoning with Fan-In

NOTE: A maximum of four HP 3PAR Storage System ports can fan-in to a single host server port.

Single Initiator to Single Target Zoning with Mixed Fan-In and Fan-Out Configurations

With single initiator to single target zoning, in a fan-in and fan-out configuration, one HP 3PAR Storage System connects to multiple host servers.

4 Allocating Storage for Access by the HP-UX Host

Creating Storage on the HP 3PAR Storage System

This section describes the general steps and commands that are required to create the Virtual Volumes that can then be exported for discovery by the HP-UX host. For additional information, see the HP 3PAR InForm OS CLI Administrator’s Manual. For complete details on creating Virtual Volumes, see the appropriate HP 3PAR documentation.

Creating Virtual Volumes

Virtual Volumes are the only data layer visible to hosts. After devising a plan for allocating space for host servers on the HP 3PAR Storage System, create the Virtual Volumes.

After devising a plan for allocating space for the HP-UX host, you need to create the required Virtual Volumes on the HP 3PAR Storage System. You 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 can optionally 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 Volume

2. 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

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

CLI command:

createvv [options] <usr_cpg> <vvname> [.<index>] <size>[g|G|t|T]

Here is an example:

# createcpg CPG_test # createvv -cnt 5 CPG_test TestLUNs 5g # showvv

----Rsvd(MB)---- -(MB) Id Name Prov Type CopyOf BsId Rd -Detailed_State- Adm Snp Usr VSize ... 6525 TestLUNs.0 full base --- 6525 RW normal 0 0 5120 5120 6526 TestLUNs.1 full base --- 6526 RW normal 0 0 5120 5120 6527 TestLUNs.2 full base --- 6527 RW normal 0 0 5120 5120 6528 TestLUNs.3 full base --- 6528 RW normal 0 0 5120 5120 6529 TestLUNs.4 full base --- 6529 RW normal 0 0 5120 5120

NOTE: To create thinly provisioned virtual volumes, an HP 3PAR Thin Provisioning license

is required.

Consult the InForm Management Console help and the HP 3PAR Command Line Reference for complete details on creating volumes for the InForm OS version that is being used on the HP 3PAR Storage System. Note that the commands and options available for creating a virtual volume may vary for earlier versions of the InForm OS.

Creating Thin Provisioned Volumes

To create Thin Provisioned volumes, see the following documents:

• HP 3PAR InForm OS Concepts Guide

• HP 3PAR InForm OS CLI Administrator’s Manual

• InForm OS Command Line Interface Reference

Exporting LUNs to the Host

This section explains how to export LUNs to the host server as VVs, referred to as Virtual LUNs (VLUNs).

To export VVs as Virtual LUNs, issue the following command:

createvlun -cnt <number> <VV_name> <LUN> <host_name>

where:

• -cnt <number> specifies that a sequence of VLUNs, as specified by the number argument,

are exported to the same system port and host that is created. The number argument can be specified as any integer. For each VLUN created, the .int suffix of the VV_name specifier and LUN are incremented by one.

• <VV_name> specifies name of the virtual volume being exported as a virtual LUN.

• <LUN> indicates that this is the starting LUN number.

• <hostname/hostdefinition> indicates that hostname is the name of the host created in

sections 2.1.1, 2.1.2, or 2.1.3.

Example:

# createvlun -cnt 5 TestLUNs.0 1 hpux-host

To verify that VLUNs have been created, issue showvlun:

# showvlun Active VLUNs Lun VVName HostName -Host_WWN/iSCSI_Name- Port Type ... VLUN Templates Lun VVName HostName -Host_WWN/iSCSI_Name- Port Type 1 TestLUNs.0 hpux-host ---------------- --- host 2 TestLUNs.1 hpux-host ---------------- --- host 3 TestLUNs.2 hpux-host ---------------- --- host 4 TestLUNs.3 hpux-host ---------------- --- host 5 TestLUNs.4 hpux-host ---------------- --- host ...

Restrictions on Volume Size and Number

Follow the guidelines for creating virtual volumes (VVs) and Virtual LUNs (VLUNs) in the HP 3PAR InForm OS CLI Administrator’s Manual while adhering to these cautions and guidelines:

• This configuration supports sparse LUNs (meaning that LUNs may be skipped). LUNs may

also be exported in non-ascending order (e.g. 0, 5, 7, 3).

• The HP 3PAR Storage System supports the exportation of VLUNs with LUNs in the range from

0 to 16838. Testing was limited to 256 LUNs per storage server port (target) using LUN numbers 1 to 256.

• The maximum LUN size that can be exported to a HP-UX host is 16TB when the installed

InForm OS version is 2.3.x. or later. The upper limits on a HP-UX host is dependant on the LVM version. See LVM Version 2.0 Volume Groups in HP-UX 11i v3 and LVM Version 1.0 Volume Groups in HP-UX 11iv2 on http://www.hp.com.

Restrictions on Dynamic LUN Expansion

Dynamic LUN Expansion (DLE) is currently not supported on HP-UX 11iv3 and HP 3PAR Storage systems.

• Beginning with HP-UX 11iv3 March 2009 Update, administrators can use the online vgmodify

command to invoke Dynamic LUN Expansion (DLE) on LVM versions 2.x and 1.0. While HP 3PAR Storage Systems allow a LUN to be dynamically resized, the HP-UX Logical Volume Manager DLE feature is currently not supported with HP 3PAR Storage Systems.

• As a temporary workaround, administrators can leverage the HP-UX diskinfo command to

trigger detection of the LUN expansion by the operating system.

# diskinfo /dev/rdisk/disk100

Setting Up Multipathing Software on 11i v3

HP 3PAR supports the HP-UX native multipathing solution.

1. In Agile Addressing Mode, the persistent DSF maps /dev/disk/diskXX to the Device

WorldWide Identifier (WWID) or serial number which correlates to an HP 3PAR Storage System VV (VV WWN). This WWN is unique and is not affected by LUN path changes; the DSF is called Agile addressing.

NOTE: Additional information on Agile Addressing Mode is provided in the Next Generation

Mass Storage Stack, HP-UX 11i v3 Native Multipathing for Mass Storage, and other documents

about Storage Area Management for HP-UX 11i v3 available at http://docs.hp.com.

2. By default, the Agile Addressing Mode is enabled. After exporting, new VLUNs that are

exported while the host server is running will not be registered on the host until you issue the ioscan command. This command scans the hardware for all the new and usable devices. You can consult /var/adm/syslog/syslog.log during the discovery process to verify that the new devices are being discovered. Special device files for the new devices (raw and block device paths) that are required to access the devices are created as part of the ioscan command by internally executing the insf -e command.

# ioscan

# tail -f /var/adm/sy slog/syslog.log vmunix: 0/0/4/1/0.0x20420002ac000036.0x400a000000000000 eslpt vmunix: 0/0/4/1/1.0x21520002ac000036.0x400a000000000000 eslpt vmunix: 64000/0xfa00/0x243 esdisk

sfd[2330]: started 'insf' to create device special files for newly found devices. sfd[2330]: execution of 'insf' completed.

Always use the -N option for the ioscan command to see the persistent devices or agile devices. Without the -N option, legacy devices will be seen.

NOTE: Broken or stale device paths are displayed with S/W state of NO_HW in the output

of the ioscan -kfnNC disk command. The CLAIMED state indicates a valid disk device path existence.

Example: Without the -N option, legacy devices are shown.

# ioscan -kfnC disk Class I H/W Path Driver S/W State H/W Type Description ======================================================================= disk 19 0/0/0/3/0.6.0 sdisk CLAIMED DEVICE HP 36.4GST336753LC /dev/dsk/c8t6d0 /dev/dsk/c8t6d0s2 /dev/rdsk/c8t6d0 /dev/rdsk/ c8t6d0s2 /dev/dsk/c8t6d0s1 /dev/dsk/c8t6d0s3 /dev/rdsk/c8t6d0s1 /dev/rdsk/ c8t6d0s3 disk 7 0/0/4/1/0.18.1.0.0.0.1 sdisk CLAIMED DEVICE 3PARdataVV /dev/dsk/c11t0d1 /dev/rdsk/c11t0d1 disk 8 0/0/4/1/0.18.1.0.0.0.2 sdisk CLAIMED DEVICE 3PARdataVV /dev/dsk/c11t0d2 /dev/rdsk/c11t0d2 disk 9 0/0/4/1/0.18.1.0.0.0.3 sdisk CLAIMED DEVICE 3PARdataVV

Example: Using the -N option displays the persistent devices.

Example: The output of ioscan shows the relationship between the legacy and persistent devices.

# ioscan -m dsf Persistent DSF Legacy DSF(s) ======================================== /dev/rdisk/disk0 /dev/rdsk/c11t0d1 /dev/rdsk/c15t0d1 /dev/rdisk/disk1 /dev/rdsk/c11t0d2 /dev/rdsk/c15t0d2 /dev/rdisk/disk2 /dev/rdsk/c8t6d0

3. HP recommends that you do not use the legacy device paths; instead, migrate any application

from legacy to persistent device paths by disabling the legacy device paths. All LVM commands

20 Allocating Storage for Access by the HP-UX Host

Page 21

works with persistent device paths (DSF). Use the rmsf -v -L command to disable the legacy device paths.

# rmsf -vL WARNING: This command may be disruptive to the system. Before running this command, make sure you have first run iofind(1M) and migrated all applications using legacy device special files. Please refer to the man page of rmsf(1M) to verify the possible side effects of the option '-L'. Do you want to continue ? (You must respond with 'y' or 'n'.): y rmsf: Removing special file /dev/dsk/c0t6d0 rmsf: Removing special file /dev/dsk/c0t6d0s1 rmsf: Removing special file /dev/dsk/c0t6d0s2

NOTE: You can enable the legacy device paths any time by executing the insf -L

command. Even if you perform I/O on legacy paths, it will be internally routed through the persistent device files.

# insf -L This command will re-install all legacy I/O nodes and legacy DSFs. Do you want to continue ? (You must respond with 'y' or 'n'.): y insf: Legacy mode has been successfully enabled

Use insf -Lv to display the status as to whether Legacy Mode is enabled or disabled.

# insf -Lv insf: Legacy mode is disabled

NOTE: The rest of this document assumes that legacy path has been disabled.

4. You can use various options for the ioscan command to obtain more details.

Example: a. To show discovered devices, issue ioscan -kfnNC disk. The description field will

have HP 3PAR VV for all HP 3PAR Storage System volumes.

# ioscan -kfnNC disk Class I H/W Path Driver S/W State H/W Type Description =================================================================== disk 2 64000/0xfa00/0x0 esdisk CLAIMED DEVICE HP 36.4GST336753LC /dev/disk/disk2 /dev/disk/disk2_p2 /dev/rdisk/disk2 /dev/rdisk/disk2_p2 disk 0 64000/0xfa00/0x23e esdisk CLAIMED DEVICE 3PARdataVV /dev/disk/disk0 /dev/rdisk/disk0 disk 1 64000/0xfa00/0x23f esdisk CLAIMED DEVICE 3PARdataVV /dev/disk/disk1 /dev/rdisk/disk1

CAUTION: All I/O to the devices should use /dev/rdisk/disk for raw disk or

/dev/disk/disk for block I/O. Any partition on the device will be represented as /dev/disk/diskX_pN number.

b. To determine the connected target ports (0:4:2 and 1:5:2) use the following commands:

2) Issue showport -i on the HP 3PAR Storage System:

# showport -i N:S:P Mode State ----Node_WWN---- -Port_WWN/HW_Addr- Type ... 0:4:2 target ready 2FF70002AC000036 20420002AC000036 host 1:5:2 target ready 2FF70002AC000036 21520002AC000036 host

3) To determine the Fibre Channel HBA’s model, hardware path, and the fcd driver

instance, issue ioscan -kfnNC fc:

# ioscan -kfnNC fc Class I H/W Path Driver S/W State H/W Type Description ================================================================== fc 5 0/0/4/1/0 fcd CLAIMED INTERFACE HP AB379-60001 4Gb Dual Port PCI/PCI-X Fibre Channel Adapter (FC Port 1) /dev/fcd5 fc 6 0/0/4/1/1 fcd CLAIMED INTERFACE HP AB379-60001 4Gb Dual Port PCI/PCI-X Fibre Channel Adapter (FC Port 2) /dev/fcd6 fc 7 0/0/6/1/0 td CLAIMED INTERFACE HP Tachyon XL2 Fibre Channel Mass Storage Adapter /dev/td7 fc 8 0/0/10/1/0 fcd CLAIMED INTERFACE HP A6826-60001 2Gb Dual Port PCI/PCI-X Fibre Channel Adapter (FC Port 1) /dev/fcd8 fc 9 0/0/10/1/1 fcd CLAIMED INTERFACE HP A6826-60001 2Gb Dual Port PCI/PCI-X Fibre Channel Adapter (FC Port 2)

4) To determine the number of LUN paths for each DSF, issue ioscan -m hwpath:

# ioscan -m hwpath Lun H/W Path Lunpath H/W Path Legacy H/W Path ==================================================================== 64000/0xfa00/0x0 0/0/0/3/0.0x6.0x0 64000/0xfa00/0x17 0/0/4/1/1.0x21520002ac000036.0x0 64000/0xfa00/0x18 0/0/4/1/0.0x20420002ac000036.0x0 64000/0xfa00/0x23e 0/0/4/1/0.0x20420002ac000036.0x4001000000000000 0/0/4/1/1.0x21520002ac000036.0x4001000000000000 64000/0xfa00/0x23f

0/0/4/1/0.0x20420002ac000036.0x4002000000000000 0/0/4/1/1.0x21520002ac000036.0x4002000000000000

In the LUN path the 16 bits address following the target port ID (0x20420002ac000036) represents the LUN number where the device is seen and the addressing mode. For example, for 0x4001 (which translates to

0100000000000001) the first two bits 01 represents VSA mode and the remaining 14 bits represent the LUN number, which is LUN 1 in this example.

The host uses estp driver for target paths, eslpt for LUN paths and esdisk as disk driver.

5) You can find the health of a device, target, LUN path and determine whether it is

on or off line using the -P option. The -C option can be used to specify attributes such as target ports, disks, or individual LUN paths. The status limited means some paths are taken offline from the available multiple paths

5. A given DSF file (/dev/disk/diskXX) once allocated to a given unique device (HP 3PAR

Storage System VV) remains persistent and will not be reused for any other devices (VVs) even after the original device (VV) is removed. Whenever the actual or original VV reappears, the same DSF name is allocated.

Example: Issuing showvlun -a on the HP 3PAR Storage System shows that the HP 3PAR Storage

System VV hpcheck is exported as LUN 20.

# showvlun -a Lun VVname Host -Host_WWN/iSCSI_Name- Port Type 20 hpcheck sqahpit2 50060B00001D1192 1:5:2 host 20 hpcheck sqahpit2 50060B000068D5A4 0:4:2 host

Setting Up Multipathing Software on 11i v3 23

Page 24

Issuing ioscan -kfnNC lunpath shows that host recognizes the VV as /dev/disk/disk20.

# ioscan -kfnNC lunpath lunpath 15 0/0/4/1/0.0x20420002ac000036.0x4014000000000000 eslpt CLAIMED LUN_PATH LUN path for disk20 lunpath 16 0/0/4/1/1.0x21520002ac000036.0x4014000000000000 eslpt NO_HW LUN_PATH LUN path for disk20

Remove the LUN and reexport it as LUN 25 and you can see that /dev/disk/disk20 is recreated for LUN 25 and the LUN path for LUN number 20 goes stale (NO_HW).

HP 3PAR Storage System:

# showvlun -a Lun VVname Host -Host_WWN/iSCSI_Name- Port Type 25 hpcheck sqahpit2 50060B00001D1192 1:5:2 host 25 hpcheck sqahpit2 50060B000068D5A4 0:4:2 host

HP-UX host:

6. HP-UX 11i v3 provides the scsimgr command, which provides generic management and

diagnostic capabilities for the SCSI subsystem of the mass storage stack. Use the scsimgr command to obtain the SCSI disk status information, statistics, change multipath options, set attributes, inquiry information and to perform other task management functions such as LUN and target resets.

Example: a. Issue the scsimgr command to obtain the relationship between the hardware LUN path,

device special file (DSF), and HP 3PAR VV.

# scsimgr -p get_attr all_lun -a hw_path -a device_file -a wwid -a serial_number -a vid

The output above shows that /dev/rdisk/disk0 is a device special file for HP 3PAR Storage System VV hpcluster.0 exported as LUN 1 and verified from HP 3PAR Storage System CLI showvv and showhost commands.

c. To obtain information about the number of paths for a given disk, issue scsimgr

lun_map or scsimgr lun_map -D /dev/rdisk/disk6:

# scsimgr lun_map -D /dev/rdisk/disk6

e. The default load balancing policy is round robin. HP offers other load balancing options.

HP 3PAR has tested the round_robin and least_cmd_load load balancing options. The load balancing policy can be changed globally or for an individual disk.

Example: Issue the following commands to globally change from round_robin to

least_cmd_load:

# scsimgr get_attr -N /escsi/esdisk -a load_bal_policy SCSI ATTRIBUTES FOR SETTABLE ATTRIBUTE SCOPE : /escsi/esdisk

name = load_bal_policy current = round_robin default = round_robin saved =

# scsimgr set_attr -N /escsi/esdisk -a load_bal_policy=least_cmd_load

Verify it is changed

# scsimgr get_attr -N /escsi/esdisk -a load_bal_policy SCSI ATTRIBUTES FOR SETTABLE ATTRIBUTE SCOPE : /escsi/esdisk

name = load_bal_policy current = least_cmd_load default = round_robin saved =

Save the load_bal_policy so the change in intact even with reboots.

# scsimgr save_attr -N /escsi/esdisk -a load_bal_policy=least_cmd_load

Verify the change made

# scsimgr get_attr -N /escsi/esdisk -a load_bal_policy

i. In HP-UX 11i v3, a device WWN (HP 3PAR Storage System VV) is closely tied to its

exported LUN ID (HP 3PAR Storage System VLUN). When seeing a different device WWN (HP 3PAR Storage System VV) on a previously used LUN ID (VLUN) to prevent data corruption, the host puts the LUN into an authentication failure state where the LUN path cannot be used for I/O transfer. This state causes the host to log a message in /var/adm/syslog/syslog.log and on the console to alert the user. The user should rely on these messages and should apply the recommended corrective action, which usually consists of running the scsimgr replace_wwid command.

NOTE: scsimgr replace_wwid replaced the fcmsutil replace_dsk option

used in earlier HP-UX releases.

Example: issuing showremovevlun and createvlun shows that the HP 3PAR Storage System volume oracle1 is exported as LUN 6 and seen as /dev/rdisk/disk22 on the host.

# showvv -d

Remove the VLUN oracle1, and export oracle2 on the same LUN ID 6.

# removevlun oracle1 6 sqahpit2 # createvlun oracle2 6 sqahpit

Issuing ioscan on the HP-UX 11i v3 host shows the scsimgr replace_wwid in the syslog.log file and that the LUN path instances (19, 20) have failed the authentication.

You can use oracle2 volume with the same device name (/dev/rdisk/disk22), which was previously allocated to oracle1 and have the same LUN path instance (19, 20). This feature is very useful for cases where applications, volume manager, file system do not need to be reconfigured. Then, use the DSF option as part of the scsimgr replace_wwid command which will preserve and reuse the existing device name (/dev/rdisk/disk22).

Not using the DSF option will generate a new DSF names example (/dev/rdisk/disk23) using the same LUN path instances.

j. In cases where all the LUNs below the target port are put in authentication state, which

can happen when the target port was moved but the LUNs are same, then the target port must be authenticated. Use the following command to authenticate a target:

# scsimgr -f replace_wwid -C tgtpath -I 3 scsimgr: Successfully validated binding of LUN paths with new LUN

The target instance can be obtained using the “ioscan -kfnNC tgtpath” command

k. You can change the DSF name to a new name or to an existing stale device using the

io_redirect_dsf command. The following example shows the host converting /dev/disk/disk23 to the stale

/dev/disk/disk22.

CAUTION: All I/O should be paused and the disk reconfigured from Volume Manger

or Application before changing the name. For details, consult the appropriate HP documentation.

l. You can give alias names for the disk as a way of tracking the device names with the

HP 3PAR Storage System volume name using the alias option for set_attr in the

scsimgr command.

/dev/disk/disk22 /dev/rdisk/disk22

# scsimgr get_attr -D /dev/rdisk/disk22 ... current = 0x50002ac0024f0036 --> Oracle2 (InServ VV name)

# scsimgr -p get_attr all_lun -a device_file -a alias ... /dev/rdisk/disk23:oracle2

7. You can list and remove all stale devices in the system using the following commands:

# ioscan -s --> lists all stale devices Class I H/W Path Driver ================================ disk 19 0/0/0/3/0.6.0 sdisk fcp 0 0/0/4/1/0.18 fcd_fcp ext_bus 11 0/0/4/1/0.18.1.0.0 fcd_vbus disk 7 0/0/4/1/0.18.1.0.0.0.1 sdisk disk 8 0/0/4/1/0.18.1.0.0.0.2 sdisk

8. The maximum volume size that can be created and exported on the storage server port is

currently 2096128 MB (2047G). HP-UX is capable of registering a VV of this size. Use the diskinfo or scsimgr command or SAM tool to display the volume size of the exported LUN.

6. PVLinks, a component of Logical Volume Manager (LVM), can be used with storage server VVs that are exported on multiple paths to the host server to provide path failure management.

PVLinks is an alternate pathing scheme where a primary and one or more alternate paths are defined for a device. The primary path is used until it fails, which causes one of the alternate paths to be used until the primary path is restored. In order for path failover with PVLinks to work, host I/O must be pointed at the LVM Logical Volume device, not at the raw or block special files in /dev/rdskand /dev/dsk.

WARNING! Because HP-UX sees every path to a device (i.e., a single storage server VLUN)

as a different device (e.g., cxt0d0 and cyt0d0), the potential to overwrite data on a LUN exists if I/O is performed directly to the /dev/dsk/ or /dev/rdsk/ special files. The PVLinks feature is part of LVM volume management. Refer to HP LVM documentation (available at

http://docs.hp.com) for information on using PVLinks. One such reference is the following HP

document: Managing Systems and Workgroups: A Guide for HP-UX System Administrators HP, 9000, Computers Edition 5Manufacturing Part Number: B2355-90742 Chapter 6: Administering a System: Managing Disks and Files Section: Setting Up Alternate Links to a Physical Volume.

Alternate links (paths) to a volume are defined at the volume group level using the vgcreate command or by using the SAM GUI.

# sam > Disk and File systems > Volume Groups & Logical Volumes

The order of failover paths specified during volume creation is important, as the failover priority will be considered in the same order as used when the volume was created. For example:

# vgcreate <volume name> <path1> <path2> <path3>…<pathn>

The failover path for the primary active path will be increased by 1 up to path n.

NOTE: If you are using the SAM utility to create volume groups, it creates all possible

alternate links by default.

After the primary link has recovered, LVM will automatically switch the active I/O from the alternate path to the primary path unless you previously instructed it not to by using the pvchange LVM command.

After initial volume-group setup, path management is manipulated at the physical-volume level using HP-UX pv... commands. To display the paths to a device, and the status of each path, use HP-UX's pvdisplay /dev/dsk/... command. To display the paths to all devices within a volume-group, use HP-UX's vgdisplay -v command. The following example show partial output from these commands:

# vgdisplay -v

the PVLinks feature to manage device paths.

7. If the VERITAS Volume Manager's DMP driver is to be used, make the newly-registered VLUNs visible to the DMP layer using the following command which causes VxVM to rebuild its view of the device nodes:

# vxdctl enable

NOTE: LVM and VxVM may coexist on the same system but should not be used to manage

the same devices.

NOTE: Remember to create raw and block device paths for the exported VLUNs using

HP-UX's ioscan and insf commands before executing any LVM and VxVM commands for the new devices.

NOTE: The driver for AB379A, A6826A is fcd and driver for A6795A, A5158A is td.

Replace fcd to td if using the A6795 or A5158 HBA in the below examples. The below example is for the A6826A HBA.

8. The fcmsutil utility can be used to display important information about each HBA port using the port's /dev/fcd<instance> device node. The fcd instance number is shown in the output of the ioscan -fun command.

11. To find the storage volume serial number for the corresponding disk id on the HP-UX host, use the cstm command. The HP Online diagnostic tool must be installed to access the cstm command. For example:

# cstm # selclass type disk # info # infolog . . . Hardware path: 0/2/0/0.8.0.0.0.0.4 The selected device is not supported by this tool. Inaccurate information could be displayed by the tool. Product Id: VV Vendor: 3PARdata Device Type: SCSI Disk Firmware Rev: 0000 Device Qualifier: 3PARdataVV Logical Unit: 4 Serial Number: 003B003E Capacity (M Byte): 4096.00 Block Size: 512 Max Block Address: 8388607 . . .

Check the ioscan -fun disk for the given hardware path and use the HP 3PAR Storage System CLI command showvlun -lvw or showvv -d to get the volume name. The data which matches is in bold font:

# showvlun -lvw -host <hostname> . . . Active VLUNs Lun VVname -----VV_WWN----- Host ----Host_WWN---- Port Type 4 hpuxN.0 50002AC0003B003E hp 50060B0000101A4C 1:0:3 host 4 hpuxN.0 50002AC0003B003E hp 50060B00000670A8 2:1:1 host . . .

12. If an HP 3PAR Storage System node is rebooted or an HP 3PAR Storage System Cluster is rebooted and the connection type is Direct, performing an ioscan or I/O on any storage volume connected to the Agilent A6795A, A5158A HBA is required in order to see the host WWN with the showhost command. This is because the HPUX host driver log's into the target port only on doing one of the above operations.

40 Allocating Storage for Access by the HP-UX Host

Page 41

6. To find the storage volume serial number for the corresponding disk id on the HP-UX host, use

the cstm command. The HP Online diagnostic tool must be installed to access the cstm command. For example:

# cstm # selclass type disk # info # infolog . . . Hardware path: 0/2/0/0.8.0.0.0.0.4 The selected device is not supported by this tool. Inaccurate information could be displayed by the tool.

Product Id: VV Vendor: 3PARdata Device Type: SCSI Disk Firmware Rev: 0000 Device Qualifier: 3PARdataVV Logical Unit: 4 Serial Number: 003B003E Capacity (M Byte): 4096.00

Block Size: 512 Max Block Address: 8388607

. . .

Check the ioscan -fun disk for the given hardware path and use the HP 3PAR Storage System CLI command showvlun -lvw or showvv -d to get the volume name. The data which matches is in bold font:

# showvlun -lvw -host <hostname> . . . Active VLUNs Lun VVname -----VV_WWN----- Host ---- Host_WWN---- Port Type

4 hpuxN.0 50002AC0003B003E hp 50060B0000101A4C 1:0:3 host 4 hpuxN.0 50002AC0003B003E hp 50060B00000670A8 2:1:1 host

. . .

7. If an InServ node is rebooted or InServ Cluster is rebooted and the connection type is Direct,

performing an ioscan or I/O on any storage volume connected to the Agilent A6795A, AH402A HBA is required in order to see the host WWN with the showhost command. This is because the HPUX host driver logs into the target port only on performing one of the above operations.

5 Removing HP 3PAR Devices on the Host Server

To remove a VV from the HP-UX 11i v3 or 11i v2 host, complete the following steps

1. Consult the appropriate HP-UX document about how to remove a specific volume type (e.g., VxVM, LVM).

2. Remove the VLUN from the HP 3PAR Storage System by issuing removevlun <VVname>

<LUN> <host>.

# removevlun testvlun 0 hpux-host

6 Booting the Host from the HP 3PAR Storage System

Refer to HP-UX boot over SAN from http://docs.hp.com to learn the benefits of configuring HP-UX to boot from the HP 3PAR Storage System.

HP 3PAR Storage System Setup Requirements

Booting from the HP 3PAR Storage System is supported in fabric and direct connect modes. Make sure you have allocated enough space when creating your virtual volumes to be able to

install your HP-UX OS. To configure the HP 3PAR Storage System, see “Configuring the HP 3PAR Storage System Running

InForm OS 3.1.x and OS 2.3.x” (page 6). After creating your first virtual volume, you must export

it to your HP-UX host.

HP-UX Itanium Host HBA Considerations

You need to use the HBA’s EFI version at the required minimum to handle booting from the HP 3PAR Storage System.

1. To prepare host, install required firmware for host HBAs to enable boot from the HP 3PAR Storage System. Collect and record the WWN of HBAs installed on the host. Check the memory size and give plenty of swap space on the boot volume. Decide the capacity of the boot volume before OS installation.

NOTE: For Itanium systems, install the supported EFI firmware for the AB379A/B, A6826A,

A6795A cards. The firmware is downloadable from http://www.hp.com by searching the HBA model. Those versions of firmware are essential to enable the boot over SAN feature.

Here are the firmware and driver information for 3 major types of HBA on HP hosts.

Table 2 HBA and EFI Version

2. Prepare boot volume on HP 3PAR Storage System. Refer to “Creating Storage on the HP 3PAR Storage System” (page 17) to setup the boot

volume and export it to the host. Use the WWN recorded in Step 1.

3. Connect cable between host HBA port and HP 3PAR Storage System HBA port. Both direct and fabric connections are supported.

4. Power on host and check MP firmware level, refer to section 7 for requirements. Upgrade firmware if needed. Then insert installation DVD and boot from DVD to this point:

Installation from HP-UX 11i v2 or 11i v3 DVDs
