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.
