HP-UX iSCSI Host to MDS/IPS-8 Configuration Example

Document ID: 46243

Updated: Nov 29, 2005

   Print

Introduction

Cisco iSCSI drivers, which reside on the server, are a key component of an iSCSI solution. These iSCSI drivers intercept Small Computer System Interface (SCSI) commands, encapsulate them into IP packets, and redirect them to the Cisco SN 5420, Cisco SN 5428, Cisco SN 5428-2, or Cisco MDS/IPS-8.This document provides sample configurations for the HP-UX iSCSI host to SN 5428.

Prerequisites

Requirements

Before you attempt this configuration, make sure that you meet these requirements:

  • Install the iSCSI driver that is compatible to your HP-UX version.The most current version of the driver can be found at the Cisco iSCSI Driver (registered customers only) download page on Cisco.com. The README.txt file is included in the driver zip(tar) file. The README contains information about the license agreement, driver installation and configuration instructions, and a technical overview of the driver architecture.

  • The operating system requirements and patch requirements are described in the System Requirements section of the Cisco iSCSI Driver for HP-UX Release Notes.

Components Used

The information in this document is based on these software and hardware versions:

  • HP-UX 9000/800 A500 server with two processors.

    Note: In this lab setup, there is no separate Ethernet adapter for iSCSI, and the one in use is 100 Mb. In any realistic environment, you have a separate Gigabit Ethernet (GE) adapter(s) as your iSCSI initiator(s).

Conventions

The Cisco MDS 9000 that is used in this document refers to any Fibre Channel (FC) switch product in the MDS 9000 family (MDS 9506, MDS 9509, MDS 9216). The Cisco Intrusion Prevention System (IPS) blade refers to IP Storage Services Module. For more information on document conventions, refer to the Cisco Technical Tips Conventions.

Background Information

The Cisco Intrusion Prevention System (IPS) module provides IP hosts access to Fibre Channel (FC) storage devices. The IPS module is DS-X9308-SMIP. It provides transparent SCSI routing. IP hosts that use iSCSI protocol can transparently access iSCSI targets on the FC network The IP host sends SCSI commands encapsulated in iSCSI Protocol Data Units (PDUs) to a MDS 9000 IPS port over a TCP/IP connection. On the IPS module, connectivity is provided in the form of GE interfaces that are appropriately configured. The IPS module enables you to create virtual iSCSI targets and maps them to physical FC targets available in the FC SAN. It presents the FC targets to IP hosts as if the physical targets were attached to the IP network.

Each iSCSI host that requires access to storage through the IPS module needs to have a compatible iSCSI driver installed. With the help of the iSCSI protocol, the iSCSI driver allows an iSCSI host to transport SCSI requests and responses over an IP network. From the perspective of a host operating system, the iSCSI driver appears to be a SCSI transport driver similar to a FC driver for a peripheral channel in the host. From the perspective of the storage device, each IP host appears as a FC host. Routing SCSI from the IP host to the FC storage device consists of these main actions:

  • Transporting iSCSI requests and responses over an IP network between hosts and the IPS module

  • Routing SCSI requests and responses between hosts on an IP network and the FC storage device (converting iSCSI to FCP and FCP to iSCSI). This routing is performed by the IPS module.

  • Transporting FCP requests or responses between the IPS module and FC storage devices

The IPS module does not import FC targets to iSCSI by default. Either dynamic or static mapping must be configured before the IPS module makes FC targets available to iSCSI initiators. When both are configured, statically mapped FC targets have a configured name. This document provides an example of static mapping. With dynamic mapping, each time that the iSCSI host connects to the IPS module, a new FC N port is created and the nWWNs and pWWNs allocated for this N port may be different. Use the static mapping method if you need to obtain the same nWWNs and pWWNs for the iSCSI host each time it connects to the IPS module. Static mapping can be used on the IPS module to access intelligent FC storage arrays that have access control and logical unit numbers (LUN) mapping and masking configurations based on the initiator's pWWNs or nWWNs.

You can control access to each statically-mapped iSCSI target with the creation of a specific list of IPS ports on which the target is advertised and the creation of a list of iSCSI initiator node names allowed to access it. FC zoning-based access control and iSCSI-based access control are the two mechanisms by which access control can be provided for iSCSI. Both methods can be used simultaneously. In this configuration default zoning is permitted for specific VSAN. IPS modules use both iSCSI node name-based and FC zoning-based access control lists to enforce access control during iSCSI discovery and iSCSI session creation.

  • iSCSI discovery: When an iSCSI host creates an iSCSI discovery session and queries for all iSCSI targets, the IPS module returns only the list of iSCSI targets this iSCSI host is allowed to access based on the access control policies.

  • iSCSI session creation: When an IP host initiates an iSCSI session, the IPS module verifies if the specified iSCSI target (in the session login request) is a static mapped target, and if true, verifies if the IP host's iSCSI node name is allowed to access the target. If the IP host does not have access, its login is rejected.

The IPS module, then creates a FC virtual N port (the N port may already exist) for this IP host and does a FC name server query for the FCID of the FC target pWWN that is accessed by the IP host. It uses the IP host virtual N port's pWWN as the requester of the name server query. Thus, the name server does a zone-enforced query for the pWWN and responds to the query. If the FCID is returned by the name server, then the iSCSI session is accepted. Otherwise, the login request is rejected.

Configurations

This document uses the configurations shown here:

  • Ape (HP 9000/800 A500 HP-UX 11.00)

  • Vatican (MDS 9216)

Ape (HP 9000/800 A500 HP-UX 11.00)
On the HP-UX host only the file /etc/iscsi.conf has to be modified:

[/]# cat /etc/iscsi.conf
 # iSCSI configuration file - see iscsi.conf(4)
 # DiscoveryAddress Settings
 # -------------------------
 # Add "DiscoveryAddress=xxx" entries for each iSCSI router instance.
 # The driver attempts to discover iSCSI targets at that address
 # and make as many targets as possible available for use.
 # 'xxx' can be an IP address or a hostname.  A TCP port number can be
 # specified by appending a colon and the port number to the address. 
 # All entries have to start in column one and must not contain any 
 # whitespace.
 #
 # Example:
 #
 # DiscoveryAddress=scsirouter1
  DiscoveryAddress=10.48.69.242 

 !--- Configure the IP address of the GE interface that acceps iSCSI request from your host.

 # The DiscoveryAddress Settings can take following entry.
 #
 # 1) Authentication Settings
 # 2) ConnectionTimeout Settings

 !--- Other required driver parameters could be changed in the iscsi.conf file.

 ......

 [/]# cat /etc/iscsi.bindings 
 # iSCSI bindings, file format version 1.0.
 # NOTE: this file is automatically maintained by the iSCSI daemon.
 # You do not need to edit this file under most circumstances.
 # If iSCSI targets in this file have been permanently deleted, you 
 # may wish to delete the bindings for the deleted targets.
 #
 # Format:
 # bus   target  iSCSI

!--- The iSCSI driver discovery daemon process looks up each discovered
!--- target in the /etc/iscsi.bindings file. If an entry exists in the file for the target,
!--- the corresponding SCSI target ID is assigned to the target. If no entry
!--- exists for the target, the smallest available SCSI target ID is assigned
!--- and an entry is written to the /etc/iscsi.bindings file for this target.



!--- Note that the /etc/iscsi.bindings file permanently contains entries
!--- for all iSCSI targets ever logged into from this host. If a target is
!--- no longer available to a host, you can manually edit the file and remove
!--- entries so that the obsolete target no longer consumes a SCSI target ID.
!--- If you know the iSCSI target name of a target in advance, and you want
!--- it to be assigned a particular SCSI target ID, you can add an entry
!--- manually. You must stop the iSCSI driver before editing the
!--- /etc/iscsi.bindings file. The maximum number of targets is 14.



!--- Enter [/]#/sbin/init.d/iscsi start to manually start the iSCSI driver.


!--- Enter [/]#/sbin/init.d/iscsi stop to manually stop the iSCSI driver.
