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 SN5428-2, or Cisco MDS/IPS-8. This document provides sample configurations for Solaris iSCSI host to MDS/IPS-8.

Before You Begin

Background Theory

The IP Storage 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 SCSI (FCP) 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 (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 locally 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 IP Storage 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 IP Storage module 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.

Configure

In this section, you are presented with the information to configure the MDS 9216 and Cisco iSCSI Driver for Solaris.

Note: To find additional information on the commands used in this document, use the Cisco MDS 9000 Family Command Reference and Cisco MDS 9000 Family Software Configuration Guide.

Network Diagram

This document uses the network setup shown in the diagram below.

Configurations

This document uses the configurations shown below.
  • Vuk (Windows Server 2003)
  • Canterbury (MDS 9216)

Vuk (Windows Server 2003)
The initial configuration tasks consist of the following actions:

  • Setting the iSCS Itarget IP addresses of MDS 9000 series systems that the driver will access.

  • Setting the iSCSI target authentication user name and passwords.
  • Saving the iSCSI target configuration, and setting the driver's boot type.
To configure the driver, perform the following steps:
  1. Log on to the computer as a user with administrator privileges.
  2. Click Start, point to Settings, click Control Panel and then double click iSCSI Config.

    The Iscsi Config program causes the Cisco iSCSI config for Win 2000/XP/2003 dialog box to be displayed.

  3. At the Cisco iSCSI config for Win 2000 dialog box, configure the IP address of a SCSI routing instance in an MDS 9000 series system as follows:

    • At the Target Host Names/IP Addresses text box, type the IP address of a SCSI routing instance in an MDS 9000 Series system. In this configuration example, the IP address is 10.48.69.222.

    • Click Add. The IP address is displayed in the display area below the Target Host Names/IP Addresses text box.

  4. Click Save and Exit.

  5. Restart the computer.

Troubleshooting Procedure

Below is troubleshooting information relevant to this configuration.
  • Displays from Vuk (Windows Server 2003)
  • Displays from Canterbury Cisco MDS 9216

Displays from Vuk (Windows Server 2003)

On the Cisco iSCSI config window, click on Status to check if the host has successfully logged into the iSCSI targets. On the command line, issue netstat -an | find/i "established" to see ESTABLISHED TCP sesions between 10.48.69.222.

To see the new disks, right click My Computer on the desktop. Double click on Computer Manager.

In the console tree under System Tool, click Device Manager

For the proper functioning of the driver under Windows 2003 Server, the driver needs to create a pseudo disk drive. This will show up as an unknown disk under the Disk Management MMC application. The user can ignore this, as it does not affect the performance or functioning of the system in any way. It must not be deleted.

To manage the storage, right click My Computer on the desktop. Double click on Computer Manager.

In the console tree under Storage, click Disk Management.
