10–iSCSI Protocol

iSCSI Boot

107 BC0054508-00 J

3. To boot through an offload path, set the HBA Boot Mode to Enabled.

To boot through a non-offload path, set the HBA Boot Mode to Disabled.

(This parameter cannot be changed when the adapter is in multi-function

mode.)

If CHAP authentication is needed, enable CHAP authentication after determining

that booting is successful (see “Enabling CHAP Authentication” on page 92).

Other iSCSI Boot Considerations

Consider these additional factors when configuring a system for iSCSI boot.

Changing the Speed and Duplex Settings in Windows Environments

Changing the Speed & Duplex settings on the boot port using Windows Device

Manager when performing iSCSI boot through the offload path is not supported.

Booting through the NDIS path is supported. The Speed & Duplex settings can be

changed using the QCS management utility for iSCSI boot through the offload and

NDIS paths.

Locally Administered Address

A user-defined MAC address assigned through the Locally Administered

Address property of the Advanced section on the QCS Configurations page is

not supported on iSCSI boot-enabled devices.

Virtual LANs

Virtual LAN (VLAN) tagging is not supported for iSCSI boot with the Microsoft

iSCSI software initiator.

“DD” Method of Creating an iSCSI Boot Image

If installation directly to a remote iSCSI target is not an option, use the “DD”

method as an alternate way to create such an image. This method requires you to

install the image directly to a local hard drive, and then create an iSCSI boot

image for the subsequent boot.

To create an iSCSI boot image with “DD”:

1. Install Linux OS on your local hard drive and ensure that the Open-iSCSI

initiator is up to date.

2. Ensure that all run levels of network service are on.

3. Ensure that the 2, 3, and 5 runlevels of iSCSI service are on.

4. Update iscsiuio. You can get the iscsiuio package from the QLogic CD. This

step is not needed for SUSE 10.

5. Install the linux-nx2 package on your Linux system. You can get this

package from the QLogic CD.
