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.
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 Remote system configuration.
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.

Enabling the hosted server boot device
The iSCSI HBA installed in an xSeries or IBM BladeCenter acts as a boot device during the boot process, based on the configured parameters.
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.
When the xSeries server has multiple iSCSI HBAs installed, only one of these must be configured as the boot device.
The IBM BladeCenter server iSCSI HBA is a dual port adapter. Only one port is required to be configured as a boot device.
Boot Modes and Parameters
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.
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.
Integrated DHCP server
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 Integrated DHCP server.
