Introduction
Cisco's iSCSI drivers, which reside on the server, are a key component of the 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 Solaris iSCSI host to SN 5428.
Prerequisites
Requirements
Before attempting this configuration, ensure that you meet these requirements:
-
Before you create the iSCSI configuration on the SN 5428, you need to install the iSCSI driver that is compatible to your Solaris version. The most current version of the driver can be found at the Cisco iSCSI Driver for Sun Solaris (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 Sun Solaris Release Notes.
-
The Cisco iSCSI Driver for Sun Solaris runs only on SPARC machines. The driver does not work with any other processor types (for example, x86).
Components Used
The information in this document is based on these software and hardware versions:

Background Theory
SCSI routing provides IP hosts with access to Fibre Channel (FC) storage devices as if the storage devices were directly attached to the hosts. Access to devices is managed primarily in the SN 5428 storage router. An iSCSI target is an arbitrary name for a group of physical storage devices. The iSCSI targets are created and mapped to physical storage devices attached to the SN 5428. The storage router presents the iSCSI targets to IP hosts as if the physical storage devices were directly attached to the hosts. With SCSI routing, storage devices are not aware of each IP host; the storage devices are aware of the SN 5428 and respond to it as if it were one FC host. SCSI routing consists of routing SCSI requests and responses between hosts in an IP network and FC storage.
Each host that requires IP access to storage by way of an SN 5428 storage router needs to have a compatible iSCSI driver installed. With the iSCSI protocol, the iSCSI driver allows an IP 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 or FC driver for a peripheral channel in the host. SCSI routing consists of these main actions:
-
Transporting SCSI requests and responses over an IP network between the hosts and the SN 5428 storage router.
-
Routing SCSI requests and responses between hosts on an IP network and FC storage.
-
Transporting SCSI requests and responses between the SN 5428 storage router and FC storage.
In the SN 5428 storage router, SCSI routing occurs through the mapping of physical storage devices to iSCSI targets. You can map an iSCSI target to multiple physical devices. An iSCSI target always contains at least one Logical Unit Number (LUN). Each LUN on an iSCSI target is mapped to a single LUN on a physical storage target.
You can choose either of two types of storage mapping: target-and-LUN mapping or target-only mapping. Target-and-LUN mapping maps an iSCSI target and LUN combination to a physical storage target and LUN combination. Target-only mapping maps an iSCSI target to a physical storage target and its LUNs.
With target-and-LUN mapping, an iSCSI target name and iSCSI LUN number are specified and mapped to the physical storage address of one LUN; either a WWPN + LUN (World Wide Port Name + LUN) combination, a LUN ID (unique LUN identifier), or a LUN serial number.
If the LUN is available, it is made available as an iSCSI LUN and numbered with the iSCSI LUN number specified. For example, if an iSCSI target and iSCSI LUN specified as Database, LUN 9 were mapped to the physical storage address, WWPN 3100112233445566, LUN 12, LUN 12 would be available as one iSCSI LUN. An iSCSI driver would see the iSCSI target named Database, with one iSCSI LUN identified as LUN 9. The iSCSI LUN would appear as one storage device to a host.
With target-only mapping, an iSCSI target name is specified and mapped to the physical storage address of a storage controller only, a WWPN. Any LUNs that are available in the storage controller are made available as iSCSI LUNs and are numbered the same as the LUNs in the storage controller. For example, if an iSCSI target specified as Webserver2000 were mapped to the physical storage address WWPN 3100112233445577, and LUNs 0 through 2 were available in that controller, those LUNs would become available as three iSCSI LUNs. An iSCSI driver would see the iSCSI target named Webserver2000 as a controller with three iSCSI LUNs identified as LUN 0, LUN 1, and LUN 2. Each iSCSI LUN would appear as a separate storage device to a host.
Access for SCSI routing is controlled in the IP hosts and the storage router. In an IP host, the iSCSI driver is configured with the Gigabit Ethernet (GE) IP address of the SCSI routing instance in the storage router with which the host is to transport SCSI requests and responses. In a storage router, access is controlled through an access list and a VLAN Identifier (VID) number of the hosts. Additionally, access can be further controlled in the SN 5428 through authentication.
