iSCSI Protocol

Assumptions

About this Document
The SCSI transport protocol iSCSI maps block-oriented (CDB) storage data over TCP/IP networks (through iSCSI PDUs). The iSCSI protocol enables universal access to storage devices and storage-area networks (SANs) over standard Ethernet-based TCP/IP networks. These networks may be dedicated networks or may be shared with traditional Ethernet applications. IP LAN/WAN routers and switches can be used to extend the IP storage network to the wide area of applications such as synchronous and asynchronous remote disk copy or tape backup and restore.
Note: Although the iSCSI protocol is written as a complete data transport from host to storage this
chapter will only discuss the current HP supported topology of iSCSI hosts to Fibre Channel storage.
The reader should have a thorough understanding of HP’s Fibre Channel Storage networking products including FC switches and storage as well as a basic understanding of TCP/IP networking.

iSCSI in a Heterogeneous SAN
Although the iSCSI protocol is written as a complete data transport from host to storage this chapter will only discuss the current HP supported topology of iSCSI hosts to Fibre Channel storage using the HP SR2122 iSCSI Router.
For further details please read “HP StorageWorks iSCSI storage router 2122 User Guide PN: 304835-002” Section 4 -SCSI Routing Overview.

Typical Network Structure

The addition of iSCSI to the SAN means that two data protocols need to be configured/ managed – TCP/IP and Fibre Channel. IP hosts with iSCSI drivers access the SR2122 through an IP network connected to the Gigabit Ethernet interface of each SR2122. The SR2122 accesses FC storage devices connected to the Fibre Channel interfaces of each SR2122.
A typical IP/FC network example:

iSCSI Initiator

The IP host, or iSCSI Initiator uses the iSCSI Driver to enable target resource recognition & attachment to the SR2122 over IP. The iSCSI driver is configured with the Gigabit Ethernet IP address of each SCSI routing instance running on the SR2122 with which the host is to transport SCSI requests and responses. The iSCSI initiator sees the storage resources (LUNs) as if they were just local drives attached directly to the server.
On the SR 2122, IP host access is controlled through an access list and optional VLAN identifier (VID).
The iSCSI Initiator may use multiple NIC cards with teaming for failover. The term “team” refers to the concept of multiple network adapters working together as a single network adapter, commonly referred to as a Virtual Network Adapter.

IP Network

The IP network is the infrastructure used to transfer data between the iSCSI initiator and the HP SR2122.

SR2122 iSCSI router

The HP SR2122 iSCSI Router is the bridge between the iSCSI Initiators and the SAN storage that converts IP to FC protocol and provides iSCSI Initiator access to FC storage.
iSCSI in a Heterogeneous SAN
SCSI routing provides IP hosts with access to FC storage devices as if the storage devices were directly attached to the hosts, with access to devices being managed primarily in the Storage Router. An iSCSI target (also called logical 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 Storage Router. The Storage Router presents the iSCSI targets to IP hosts (iSCSI initiators) 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 Storage Router and respond to it as if it were one FC host.
You can configure storage routers in a cluster to allow the storage routers to back each other up in case of failure.
A storage router cluster consists of two to four storage routers connected as follows:
Connected to the same hosts
Connected to the same storage systems
Connected to each other through their management and high availability (HA) interfaces
In a cluster, storage routers continually exchange HA information to propagate configuration data to each other and to detect failures in the cluster. The storage routers exchange HA information through two separate networks: one connected to the management interface of each Storage Router and the other connected to the HA interface of each Storage Router. To make sure that HA information is exchanged reliably between storage routers, the storage routers balance the transmission of HA information between the management and the HA interfaces.
SR2122 access is controlled through an access list and a VLAN identifier (VID) number of the hosts. An access list enables access to storage devices attached to the Storage Router with any combination of host IP address(es), CHAP user name(s), or iSCSI name(s). An access list contains these combinations. Host VID enables access to storage devices according to the VID of each host. You can use a combination of access lists and VIDs to configure access in the Storage Router; that is, you can specify that certain hosts according to IP address in a VLAN can access storage devices attached to the Storage Router.

Fibre Channel SAN

A Storage Area Network is a dedicated, centrally managed, secure information infrastructure, which enables any-to-any interconnection of servers and storage. SANs are built to incorporate the best of both storage and networking interfaces: fast and efficient communications optimized for movement of large amounts of data, but with access to a wide range of other servers and storage devices on the network.
The SR2122 iSCSI Router is supported on any currently supported HP B-Series, C-Series, or M-Series switch fabric. For the latest HP switch topoligies and fabric rules, please read the “HP StorageWorks SAN Design Reference Guide” avalable at:

12 iSCSI SR2122 Storage Router: Getting Started Guide

Configuring the SR2122 iSCSI Storage Router in a SAN

Configuring the SR2122 iSCSI Storage Router in a SAN
Configuring the SR2122 in a SAN takes on five distinct steps or sections:
Setup/configuration of the SR2122 itself
Adding the SR2122 to a SAN – standalone or clustered
Serving storage to the SR2122 from the storage arrays over Fibre Channel
Serving storage to the iSCSI Initiators from the SR2122 over IP.
Setup/configuration of the iSCSI Initiators

SR2122 Setup

The SR2122 can be configured either as a standalone or clustered device. In Standalone Mode, as the name implies, the SR2122 does not have failover capabilities to other SR2122s. In Clustered Mode up to four SR2122s can be used as failover when presenting storage to iSCSI Initiators.
Note: A Standalone SR2122 can be added to a SR2122 Cluster without re-initializing the
standalone router to preserve its configuration.
For further SR2122 configuration details, please read “HP StorageWorks iSCSI storage router 2122 User Guide PN: 304835-002” Chapter 5 – Configuring the Storage Router.
Whether adding SR2122’s in Standalone or Cluster modes its important to know the WWPN of the fibre channel ports as they are needed for configuring both SAN zoning and Selective Storage Presentation (SSP).
To find the WWPN of a FC ports using the SR2122’s CLI enter:
SR2122> show interface "fc1" stats

Configuring the SR2122 iSCSI Storage Router in a SAN
To find the WWPN of a FC ports using the SR2122’s GUI, click on the FC port in the Monitor window:

Figure 2: GUI Display of the FC port WWPN

Adding a Standalone SR2122 to a SAN

The two SR2122 FC ports are recognized as F-Ports by the FC switch and as FC HBAs by the Storage Arrays. Ports FC1 and FC2 may be used but they cannot be served the same LUN from the same storage array, as multi-pathing is currently not supported.
After physically connecting the FC port(s), and if zoning is enabled, it is recommended to create a new zone that includes the FC Port WWPNs and the WWPNs of the storage arrays that will be serving storage to the SR2122.
Standalone SR2122 examples:

Figure 4: Standalone SR2122; Dual SANs

Adding a Clustered SR2122 to a SAN

Configuring the SR2122 iSCSI Storage Router in a SAN
The two SR2122 FC ports on all the clustered SR2122’s are recognized as F-Ports by the FC switch and as FC HBAs by the Storage Arrays.
After physically connecting the FC port(s), and if zoning is enabled, it is recommended to create a new zone that includes the FC Port WWPNs and the WWPNs of the storage arrays that will be serving storage to the SR2122.
Note: Important: Although Multi/Auto Pathing is not supported in a SR2122 clustered
environment,a certain level of failover is available at the SR2122 when configured in a cluster.
Normally, only one SR2122 within the cluster is responsible for the active I/O path between the iSCSI Initiator and the Storage Array, as an iSCSI Initiator’s I/O cannot be split between SR2122 Cluster members. If this active Cluster member fails the I/O can switch to another cluster member. To insure proper failover each cluster member needs one of its FC ports in the same zone.
Clustered SR2122 Example:

Figure 5: Clustered SR2122

15iSCSI SR2122 Storage Router: Getting Started Guide

Serving Fibre Channel Storage to the SR2122

Serving Fibre Channel Storage to the SR2122
Once the SR2122 is properly configured, connected and zoned within the SAN, the next step is to present storage to the router.
Where normally the storage is presented to a server, we must first get the FC storage to the SR2122, then we have to present that storage to the iSCSI Initiators over IP.
As previously mentioned, the SR2122 FC ports look like a typical Fibre Channel Host Bus Adapter to the storage array. Depending on the storage array it’s now a matter of creating LUNs and presenting them to the SR2122’s FC port. This section describes how to serve storage from each supported storage array – MSA1000, RA/MA8000, ESA/EMA12000, Enterprise Storage Array, VA and XP – to the SR2122.
The assumption is the reader is not only experienced in the initial setup of these storage arrays but also in the creation of storage volumes or LUNs. This section describes the presentation of these LUNs to the SR2122. If not, if is suggested to read the configuration/user/reference guides for the storage array in question.
Please read “HP StorageWorks SAN Design Reference Guide – September 2003 Part Number: AA-RMPNJ-TE” for the latest HP storage configurations and rules.

Presenting MSA1000 LUNs to the SR2122

MSA1000 storage volumes must be pre-configured before the LUN(s) can be detected and recognized by the SR2122. The MSA1000 can be configured either through its serial port or through the Array Configuration Utility.
Whatever method is chosen we must now use the MSA1000’s selective storage presentation (SSP) commands to restrict access to volumes that are to be served to the SR2122.
Without HP Secure Path, the MSA1000 is supported with the SR2122 accessing only one MSA controller port. This restriction disables controller failover protection.
First, the Show Connection command will determine if the MSA1000 storage array is aware of the SR2122 FC port(s).
MSA1000> show connection
Connection Name: “”
Host WWNN = 10000002-3d071bc0
Host WWPN = 28000002-3d071bc0
Profile Name = Default Profile
Unit Offset = 0
Controller 1 Port 1 Status = Online
Next, to enable an ACL, the MSA1000 Volume Unit must be assigned to the SR2122's FC port WWPN. For example, a Show Unit command may display:
MSA1000> sho units
Unit 1:
In PDLA mode, Unit 1 is Lun 2; In VSA mode, Unit 1 is Lun 1.
Unit Identifier:
Volume Status: VOLUME OK
5 Disk(s) used by lun 1:

To present Unit 1 to the SR2122, the command would be:
MSA1000> add acl wwpn=28000002-3d071bc0 unit=1
Allowing 28000002-3d071bc0 access to unit 1.
Whether the MSA 1000 is running in PDLA or VSA Mode will determine how the LUN number is presented. In PDLA, the SR2122 will see Unit 1 as LUN 2 whereas in VSA Mode the SR2122 will see the unit as LUN 1.
Note: If using SR2122 Cluster mode, the WWPN for a FC port on each SR2122 cluster member
must be added to the MSA1000 Unit.
The SR2122 should now be able to present Unit 1 as storage to iSCSI Initiators.

Presenting RA/MA8000, ESA/EMA12000, and EMA16000 LUNs to the SR2122

RA/MA8000, ESA/EMA12000, and EMA16000 (HSG80) storage volumes must be pre-configured before the LUN(s) can be detected and recognized by the SR2122. The HSG80 controllers can be configured either through its serial port or through the HSG Element Manager application found on the SAN Management appliance.
Whatever method is chosen we must now use the HSG80’s selective storage presentation (SSP) commands to restrict access to volumes that are to be served to the SR2122.
First, the Show Connection command will determine if the HSG80 is aware of the SR2122 FC port(s).
HSG80> Show Connections
!NEWCON09 WINNT OTHER 1 0D0F00 OL other 80
HOST_ID=1000-0002-3D07-1E60 ADAPTER_ID=2800-0002-3D07-1E60

HOST_ID=1000-0002-3D07-1E60 ADAPTER_ID=2800-0002-3D07-1E60
On initial discovery the SR2122 FC ports are assigned names that begin with !NEWCON# in the HSG80 connection table.
These entries may be renamed to a more user-friendly naming convention with the Rename command.
HSG80> rename !newcon09 isrfc1-p1
HSG80> rename !newcon10 isrfc1-p2

The Show Connections command will now display:

HOST_ID=1000-0002-3D07-1E60 ADAPTER_ID=2800-0002-3D07-1E60
Next, an HSG80 Volume Unit can be assigned to the SR2122’s FC port WWPN using the connection name.
For example, a Show Unit command may display:
HSG80> Show Units

D108 DISK20100

To present Unit 81 to the SR2122 the command would be:
HSG80> set D81 enable=isrfc1-p1
To verify D81 is enabled only for the SR2122 type the command:
HSG80> Show D81

Note: If using SR2122 Cluster mode the WWPN for a FC port on each SR2122 cluster member
must be added to the HSG80 Unit.
The SR2122 should now be able to present D81 as storage to iSCSI Initiators.

Presenting Enterprise Storage Array (EVA) LUNs to the SR2122

Enterprise Virtual Array (HSV110) storage volumes must be pre-configured before the LUN(s) can be detected and recognized by the SR2122. The HSV110 controllers can only be configured through the HSV Element Manager application found on the SAN Management appliance.
Note: If Secure Path is not configured on the iSCSI initiators, then only one HSV port is supported to
connect to the SR2122. Make sure only one of the four ports is included in the same SAN zone as the SR2122 FC port. Caution: This will prohibit controller failover.
The user must now use the HSV110’s selective storage presentation (SSP) commands to restrict access to volumes that are to be served to the SR2122.
First, a host entry for the SR2122 must be added to the EVA and assign its WWPN to it using the HSV Element Manager application.
Open the Storage Array icon and click on hosts. Click the button that appears on the content screen.
STEP 1: Enter/Add the Host Name Enter your host's LAN node name.
STEP 2: Enter the IP address (optional) If your host uses a static LAN IP address, enter the address. Skip this step if your host uses dynamic IP addresses.
STEP 3: Enter an adapter port World Wide Name: Enter the SR2122’s FC port WWN.
