Configuration

Configuring the iSCSI Software Initiator

After the iSCSI Software Initiator has been installed and the system has been rebooted, the following

iSCSI-specific tasks (in addition to network setup) must be done manually to complete the system setup:

1. Add the path for iscsiutil and other iSCSI executables to the root path as:

# PATH=$PATH:/opt/iscsi/bin

See “The iscsiutil tool” on page 55, for more information on iscsiutil.

2. Configure the iSCSI initiator name.

The iSCSI protocol mandates an initiator name for the host iSCSI node.

iSCSI initiator names (iSCSI names) are defined in the iSCSI Qualified Name (iqn) or IEEE EUI-64 (eui)

format.

The iSCSI Software Initiator configures a default initiator name in the iqn format.

NOTE To display the iSCSI initiator name that has been configured by default, enter:

# iscsiutil -l

If the default iSCSI initiator name configured by the iSCSI Software Initiator meets your requirements,

skip ahead to item 4.

If you want to change the iSCSI initiator name, read the following overview of the iqn and eui naming

formats. For further details, consult the iSCSI protocol specification (RFC 3720) at:

http://www.ietf.org/rfc/rfc3720.txt

iSCSI Qualified Name (iqn)

A default iSCSI iqn initiator name appears in the following example:

iqn.1986-03.com.hp:hpfcs214.2000853943

The string iqn. identifies this iSCSI initiator name as an iSCSI Qualified Name to distinguish it from an

iSCSI initiator name in the "eui." format.

1986-03. is a date code in yyyy-mm format followed by a dot. This date MUST be a date during which the

naming authority owned the domain name used in the iqn formated iSCSI initiator name.

com.hp is the reversed domain name of the naming authority (person or organization) that created this

iSCSI initiator name.

:hpfcs214 is an optional string that must comply with a character set and length boundaries that the

owner of the domain name deems appropriate. The optional string must be preceeded by a colon. The

optional string may contain product types, serial numbers, host identifiers, or software keys (e.g, it may

include colons to separate organization boundaries). The string following the colon (:) in the example

above depicts the hostname (hpfcs214) followed by the partition identifier (2000853943).
