10–iSCSI Protocol
iSCSI Boot
108 BC0054508-00 M
IP Autoconfiguration This option is specific to IPv6. Controls whether the iSCSI boot host software
will configure a stateless link-local address and/or stateful address if DHCPv6
is present and used (Enabled). Router Solicit packets are sent out up to three
times with 4 second intervals in between each retry. Or use a static IP config-
uration (Disabled).
iSCSI Parameters via
DHCP
Controls whether the iSCSI boot host software acquires its iSCSI target
parameters using DHCP (Enabled) or through a static configuration (Dis-
abled). The static information is entered through the iSCSI Initiator Parame-
ters Configuration window.
CHAP Authentication Controls whether the iSCSI boot host software uses CHAP authentication
when connecting to the iSCSI target. If CHAP Authentication is enabled, the
CHAP ID and CHAP Secret are entered through the iSCSI Initiator Parame-
ters Configuration window.
Boot to Target The first time a connection is made, this option controls whether the desig-
nated iSCSI LUN will either be:
 Not be booted from (Disabled)
 Always be booted from (Enabled)
 Not booted
After a reboot, this option must be set to Enabled and always booted from
(One Time Disabled).
This control allows the boot OS to be installed on the connected LUN, which
must be done the first time the system is setup. Afterwards, this system can
connect and boot from that installed OS image once this control is set to
Enabled.
DHCP Vendor ID Controls how the iSCSI boot host software interprets the Vendor Class ID
field used during DHCP. If the Vendor Class ID field in the DHCP Offer packet
matches the value in the field, the iSCSI boot host software looks into the
DHCP Option 43 fields for the required iSCSI boot extensions. If DHCP is dis-
abled, this value does not need to be set.
Link Up Delay Time Controls how long the iSCSI boot host software waits, in seconds, after an
Ethernet link is established before sending any data over the network. The
valid values are 0 to 255. As an example, a user may need to set a value for
this option if a network protocol, such as Spanning Tree, is enabled on the
switch interface to the client system.
TCP Timestamp Controls if the TCP Timestamp option is enabled or disabled.
Target as First HDD Allows specifying that the iSCSI target drive will appear as the first hard drive
in the system.
