7.1.5 Advanced iSCSI configuration (expert mode)
The iSCSI service running on the storage blade supports numerous configuration
options that appear in the iSCSI section of web interface tool. Users may modify any
number of parameters listed, and then click the ‘submit’ button located at the top
of the page.
Note: Users may undo all changes and re-apply the default settings by clicking the
‘Target Default settings’ button.

Alternatively, iSCSI configuration options may be set via simple edits to a text based
configuration file /etc/ietd.conf using a console window.
The configuration file contains an entry for each target entry created by the web or
cli tools. The file contains a stanza style entry for each iSCSI target that begins with
the parameter name: “Target”. The file syntax is explained in the next section. File
changes become active at next reboot or by re-starting the iSCSI service (as root):
/etc/rc.d/init.d/iscsi stop
/etc/rc.d/init.d/iscsi start
Sample ietd.conf file for iSCSI targets
Notes: Comment lines must start with a ‘#’ as first character.
A line may extend across multiple lines if last character is backslash ‘\’
Parameter values are case sensitive: "Yes" and "No"
Parameter names are case insensitive.
The file consists of a global part and zero or more "Target" stanzas.
Everything before the first Target definition belongs to the global configuration.
