ttings 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

,seeDeﬁning LU paths and Making settings on iSCSI ports and iSNS servers.

• 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,wherexxx

is the iSCSI port's location.

• Subnet mask:

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

mask is a valu

e 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 name

s 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 forma

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 Wid

eName.

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 leng

th 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.

peri

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

case-sensitive; for example, MyPort

and myport are different iSCSI aliases.

• Port number: You must assign part numbers to iSCSI ports when conﬁguring iSCSI environments.

Use LUN Manager to specify a decimal port number within the range of 1 to 65535. A port

num

ber's initial value is 3260.

• Keep-alive timer: You must specify the Keep-alive timer when conﬁguring iSCSI environments. The

Keep-alive timer is used when there is a connection between an iSCSI port and another iSCSI

nod

e. For example, if the keep-alive timer is set to 60 seconds, the array checks whether packet

communications occurred between an iSCSI port and another iSCSI node (such as a host bus

adapter or switching hub) every 60 seconds.

Use LUN Manager to specify a value within the range of 0 to 64,800 seconds. The Keep-alive timer's

itial value is 60 seconds.
