Introduction

Cisco's iSCSI drivers, which reside on the server, are a key component of an iSCSI solution. These iSCSI drivers intercept 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 Linux iSCSI host to MDS/IPS-8.

Before You Begin

Conventions

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). IPS blade refers to IP Storage Services Module. For more information on document conventions, see the Cisco Technical Tips Conventions.

Prerequisites

Before you start making your iSCSI configuration on the MDS 9000 you need to install iSCSI driver that is compatible to your Linux version. The most current version of the driver can be found at the Cisco iSCSI Driver for Linux (registered customers only) 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 Linux Release Notes.

Background Theory

The IPS module provides IP hosts access to FC storage devices. The IPS module is DS-X9308-SMIP. It provides transparent SCSI routing. IP hosts using 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 Gigabit Ethernet 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 via the IPS module needs to have a compatible iSCSI driver installed. Using 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 the following 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 vice versa). 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. In this configuration you will see an example of static mapping. With dynamic mapping, each time 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 LUN mapping/masking configuration based on the initiator's pWWNs and/or nWWNs.

You can control access to each statically-mapped iSCSI target by specifying a list of IPS ports on which it will be advertised and specifying 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 has been 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 being 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.
