Overview of LUN Manager

iSCSI port and iSNS server settings

You must make settings on iSCSI ports (and iSNS servers, if necessary) when configuring iSCSI

environments. Use LUN Manager to specify the following items when configuring iSCSI environments. For

instructions, see

Defining LU paths

” on page 75 and ”

Making settings on iSCSI ports and iSNS servers

on page 101.

IP address: You must specify the iSCSI port’s IP address when configuring iSCSI environments. In LUN

Manager, the initial value of the iSCSI port’s IP address is 192.168.0.xxx, where xxx is the iSCSI

port’s location.

Subnet mask: You must specify a subnet mask when configuring iSCSI environments. A subnet mask is

a value used for obtaining a network address from an IP address. In LUN Manager, the subnet mask’s

initial value is 255.255.255.0.

Gateway address: If a gateway is used, specify the gateway address. A gateway is hardware

connecting networks with different protocols.

iSCSI name: You must assign iSCSI names to iSCSI ports when configuring iSCSI environments. iSCSI

names are used to uniquely identify each iSCSI node. iSCSI nodes are devices that use the iSCSI

protocol for communication (for example, iSCSI ports in arrays, host bus adapters in host servers, and

switching hubs for network relaying).
iSCSI names must be specified in either of the following formats:
• eui format:

An IEEE 64-bit Extended Unique Identifier used to specify an iSCSI name. The iSCSI name begins

with eui. and is followed by the ID found by the vendor in EUI-64 format similar to the World Wide

Name.
Example: eui.02004567A425678D

• iqn format:

The iSCSI Qualified Name format used to specify an iSCSI name. For more information about

specifying iSCSI names using this format, see the iSCSI-related documentation.
If a host is connected to an iSCSI port, LUN Manager automatically displays the iSCSI name in iqn

format. iSCSI names can include 0 (zero) to 9, and a to f (letters are case-insensitive).
Example: iqn.2006.01.com.hp:iscsi-r500:model-xxx:sn-xxxxxx:lun00

The length of an iSCSI name must be 20 characters in eui format, and up to 223 characters in iqn

format. iSCSI names can include letters, numbers, periods (.), hyphens (-), and colons (:); but cannot

include double-byte characters. iSCSI names are case-insensitive.

iSCSI alias: An iSCSI alias is a nickname you assign to an iSCSI name. Assigning iSCSI aliases is

optional, but helpful, when managing and identifying iSCSI targets.
It is difficult to identify iSCSI targets by iSCSI names because an iSCSI name consists of numerous

characters and is hard to remember. If you assign an iSCSI alias that is brief and easy to remember,

you can easily and quickly identify iSCSI targets.
The length of an iSCSI alias must be up to 32 characters. iSCSI aliases can include letters, numbers,

periods (.), hyphens (-), and colons (:); but cannot include double-byte characters. iSCSI aliases are

case-sensitive; for example, MyPort and myport are different iSCSI aliases.
