Configuring The Iscsi Boot Parameters - Dell QLogic Family of Adapters User Manual

iSCSI Configuration Using Fast!UTIL: QLogic QME8242 Mezzanine Card User's Guide
Security Settings—Press <Enter> to access Primary Boot Security Settings. Press <Enter> to enable or disable CHAP
and bidirectional CHAP, and to configure the CHAP Name and CHAP Secret. (Depending on your configuration, it may
not be necessary to configure this option.)
Target IP—When the Adapter Boot Mode is set to Manual, you must use this field to specify the IP address of the
intended iSCSI boot target.
Target Port—Enter the port used by the target. (By default, iSCSI uses port 3260. Do not modify this unless it is
necessary.)
Boot LUN—Enter the logical unit number (LUN) of the boot device. (Depending on your configuration, it may not be
necessary to change this option.)
iSCSI Name—Enter the iSCSI name of an intended boot target. (Depending on your configuration, it may not be
necessary to configure this option.)
DHCP Dynamic iSCSI Boot Configuration—Select this option to have the initiator acquire its IP address from a
DHCP server. The initiator also acquires all boot parameters for an iSCSI target if the boot parameters are specified on
the DHCP server. This setting requires advanced users to manually input vendor-specific information on the DHCP
server and in the Vendor ID field of the DHCP Boot Settings area.
Vendor ID is the identification string sent to DHCP server.
Alternate Client ID provides an alternative for DHCP clients to use instead of the dhcp-client-identifier
option. The alternate client ID is a unique identifier string sent to the DHCP server. It provides an additional
filtering option to set device-specific boot parameters. If this field is not set, a default identifier string consisting
of the devices MAC address is used.
Configure Parameters for the secondary adapter.
Select Host Adapter if you have multiple QME8242 adapters in your system, select, view, and configure the
settings of a specific QME8242 adapter.
NOTE: These options apply only to disk devices; they do not apply to tape drives and other non-disk devices.

Configuring the iSCSI Boot Parameters

This section discusses how to configure a QLogic iSCSI adapter for booting from a SAN. On a system set up to boot from a
SAN, the system BIOS must designate the iSCSI adapter as the boot controller. To locate the target boot LUN, you must
enable the QLogic BIOS on the iSCSI adapter.
To enable the QLogic iSCSI adapter to boot from a SAN:
1. During server POST, press <Ctrl+Q> to enter the QLogic iSCSI Fast!UTIL BIOS.
2. Select the I/O port to configure. By default, the Adapter Boot mode is set to Disable.
Configuring the iSCSI Boot Settings
1. From the Fast!UTIL Options menu, select Configuration Settings, and then select iSCSI Boot Settings.
2. Before you can set SendTargets, set the Adapter Boot mode to Manual.
3. Select Primary Boot Device Settings.
4. Enter the discovery Target IP and Target Port.
5. You can leave the Boot LUN and iSCSI Name fields blank only if one iSCSI target and one LUN are at the specified
address from which to boot. Otherwise, you must specify these fields to ensure that you do not boot from a volume for
some other system. After the target storage system is reached, these fields are populated after a rescan.
6. Save your changes.
7. From the iSCSI Boot Settings menu, select the primary boot device. An auto rescan of the host bus adapter finds new
target LUNs.
8. Select the iSCSI target.
NOTE: If more than one LUN exists within the target, you can choose a specific LUN ID by pressing <Enter> after you
locate the iSCSI device. Return to the Primary Boot Device Setting menu. After the rescan, the Boot LUN and
iSCSI Name fields are populated.
9. Change the value of Boot LUN to the LUN ID you want.
10. Save your changes and restart the system.
