To conﬁgure IP for subsequent use by iSCSI initiators:

1. Enter conﬁguration mode: switch# config terminal

2. Enter the interface conﬁguration mode on the Gigabit Ethernet interface (slot 2, port 2):

switch(config)# interface gigabitethernet 2/2

3. Enter the IP address (33.33.33.170) and subnet mask (255.255.255.0) for the Gigabit Ethernet

interface: switch(config-if)# ip address 33.33.33.170 255.255.255.0

4. Enable the interface: switch(config-if)# no shutdown

Presenting iSCSI hosts as virtual Fibre Channel hosts

Because you are conver ting SCSI commands to and from an iSCSI IP server to Fibre Channel storage,

the C-Series IP Storage Services Modules (IPS-4, IPS-8), Multi-protocol Services Mod ule (14/2), and

MDS 9216i sw

itch must map the ISCSI server’s I P ad dress to a unique WW PN that the Fibre Channel

Storage recognizes.

The IP Storage Services Modules (IPS-4, IPS-8), Multi-protocol Servi ces Module (14/2), and MDS 9 216i

switch have two modes to present iSCSI hosts in the Fibre Channel fabric: transparent mode a nd proxy

initiator mode. HP recommends the use of transparent mode as described in this guide.

The beneﬁtoftransparentmodeisthatitallowsaﬁner level of access control conﬁguration. In transparent

mode, each iSCSI host is presented as one virtual Fibre Channel host on the Fibre Channel fabric.

Because o

f the one-to-one mapping of IP-to-WWPN translation from iSCSI to Fibre Channel, each host

can have

different zoning in the Fibre Channel SAN or LUN access control on the Fibre Channel storage.

Transparent mode static mapping

The C-Series IP Storage Services Modules (IPS-4, IPS-8), Multi-protocol Services Module (14/2), and

MDS 9216i switch have t wo modes of mapping IP addresses: transparent-mode dynamic mapping

and transparent-mode static mapping. Because the Microsoft iSCSI Initiator does not support Dynamic

partitions, you must conﬁgure using transparent mode static m apping. Static map ping must be enabled

for each iSCSI Initiator to guarantee persistent LUN m apping from the H P Fibre Channel controller to the

iSCSI Initiator. See Conﬁguring transparent mode static m apping for instructions.

attachment to the C-Series I P Storage Services Mo dules (IPS-4, IPS-8), Multi-protocol Services Module

(14/2), and MDS 9216i switch over IP. The Microsoft iSCSI Initiator is conﬁgured with the Gigabit

Ethernet IP address of each iSCSI interface running on the C-Series IP Storage Services Modules (IPS-4,

IPS-8), Multi-protocol Services Modu le (14 /2), and MDS 9216i to which the host is to transport SCSI

req

uests and responses. The i SCSI Initiator sees the storage resources (LUNs) as if they were local

drives attached directly to the server.

HP conﬁguration utility for network interface cards

With HP ProLiant servers, an iSCSI Initiator may use multiple NIC cards with HP teaming enabled 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.

ownload the iSCSI Initiator from Microsoft's download page, and follow the installation instructions.

he download includes copying the user guide to your local disk. You can refer to the user guide in

:\Program Files\Microsoft iSCSI Initiator\uguide.doc for further information.

he ﬁrst use of the Microsoft iSCSI initiator, requires a m a nual log in to the Available Targets. After the

Available Target logins are completed with the Restore Connection button enabled, the iSCSI Initiator

automatically logs in whenever the server powers up or reboots.
