<h4 id="rzahqdisklessbootingoveriscsi">Diskless booting over iSCSI</h4>
|
||
|
|
<p>All of the iSCSI attached stand alone or IBM® BladeCenter™ servers are diskless and require
|
||
|
|
an xSeries® or IBM BladeCenter iSCSI host bust adapter (HBA) as
|
||
|
|
a boot device.</p>
|
||
|
|
<p>Both the i5/OS™ remote system configuration and the remote server iSCSI HBA must
|
||
|
|
be configured before you install or use a new integrated Windows server. See <a href="scrmtsys.htm#scrmtsys">Remote system configuration</a>.</p>
|
||
|
|
<p>The iSCSI HBA must be configured during the xSeries or IBM BladeCenter boot process using the adapter
|
||
|
|
CTRL-Q utility. It is recommended that it is configured as part of the initial
|
||
|
|
server set up. There is a minimal set of parameters required to be configured
|
||
|
|
in the hosted server iSCSI HBA. These parameters need to be matched to those
|
||
|
|
parameters configured in the remote system configuration object. The parameters
|
||
|
|
vary depending on the selected boot mode.</p>
|
||
|
|
<p>See the <a href="http://www.ibm.com/servers/eserver/iseries/integratedxseries/iscsireadme" target="_blank">iSCSI install
|
||
|
|
read me first</a>
|
||
|
|
<img src="www.gif" alt="Link outside the Information Center." />web page for details on how
|
||
|
|
to configure the hosted system iSCSI HBA as the iSCSI boot device. For details
|
||
|
|
on how to configure the set of parameters in the remote system configuration
|
||
|
|
object, see <a href="rzahqchangeremotesysconfig.htm#rzahqchangeremotesysconfig">Change remote system configuration properties</a>.</p>
|
||
|
|
<p><span class="bold">Enabling the hosted server boot device</span></p>
|
||
|
|
<p>The iSCSI HBA installed in an xSeries or IBM BladeCenter acts as a boot device during the
|
||
|
|
boot process, based on the configured parameters.</p>
|
||
|
|
<p>When the xSeries has only one iSCSI HBA, this adapter needs to be
|
||
|
|
configured as the boot device. iSCSI boot is enabled by default on all iSCSI
|
||
|
|
HBAs, but you must configure additional information.</p>
|
||
|
|
<p>When the xSeries server has multiple iSCSI HBAs installed, only
|
||
|
|
one of these must be configured as the boot device.</p>
|
||
|
|
<p>The IBM BladeCenter server iSCSI HBA is a dual port adapter. Only
|
||
|
|
one port is required to be configured as a boot device.</p>
|
||
|
|
<p><span class="bold">Boot Modes and Parameters</span></p>
|
||
|
|
<p>The iSeries™ iSCSI solution supports different boot modes. Depending on the
|
||
|
|
selected boot mode different boot parameters are required to be configured
|
||
|
|
in the hosted system iSCSI HBA.</p>
|
||
|
|
<p>The parameters are configured using the adapter CTRL-Q utility. A boot
|
||
|
|
device must be selected and configured the first time a server is being deployed.
|
||
|
|
It is recommended that the required parameters are configured as part of this
|
||
|
|
initial set up process.</p>
|
||
|
|
<p><span class="bold">Integrated DHCP server</span></p>
|
||
|
|
<p>The iSCSI attached server uses an integrated DHCP server when it is configured
|
||
|
|
to use the default or DHCP boot mode. This integrated DHCP server is not a
|
||
|
|
general purpose server. It is intended to exclusively deploy boot parameters
|
||
|
|
to the hosted server iSCSI HBA. The server is automatically configured with
|
||
|
|
the parameters provided in the remote system configuration when a network
|
||
|
|
server description (NWSD) is varied on. For more information, see <a href="rzahqintegratedhcpserver.htm#rzahqintegratedhcpserver">Integrated DHCP server</a>.</p><img src="deltaend.gif" alt="End of change" /><img src="deltaend.gif" alt="End of change" />
