Limitations and known issues

The following are limitations to iSCSI boot for Linux.

DNS is not supported

Installation

On some blade systems, after the system is booted and the GUI is started, the system console on a
KVM switch may report that it is in an unsupported mode. The iLO2 integrated remote console works

fine. This is a problem with the SLES 10 installation procedure and not with the iSCSI boot

installation procedure.

After booting a system over iSCSI, if the SmartStart Linux PSP is installed it changes the default boot
kernel in the boot loader conf file /boot/grub/menu.lst. The PSP default kernel does not support

iSCSI boot. Update the /boot/grub/grub.conf to make the default boot kernel point to the entry 0.

If PXE is used to install the operating system on an iSCSI target for a c-Class BladeSystem, disable

the internal disk controller with RBSU (F9 during POST). After the install is complete, the internal
controller can be re-enabled.

System hangs

After a server is booted over iSCSI, do not bring down the network interface that iSCSI is using or a
system hang results.

Attempting to boot from an iSCSI disk that has no operating system installed on it may result in a
system hang.

If the system crashes, the diskdump utility that would normally take a system dump will not work on
an iSCSI booted system.
