Linux iSCSI Boot Setup
Linux iSCSI boot is supported on Red Hat Enterprise Linux 5.5 and later and
SUSE Linux Enterprise Server 11 SP1 and later in both the offload and
non-offload paths. Note that SLES 10.x and SLES 11 have support only for the
non-offload path.
1.
For driver update, obtain the latest QLogic Linux driver CD.
2.
Configure the iSCSI Boot Parameters for DVD direct install to target by
disabling the Boot from target option on the network adapter.
3.
Configure to install through the non-offload path by setting HBA Boot Mode
to
Disabled
in the NVRAM Configuration. (
Note
: This parameter cannot be
changed when the adapter is in Multi-Function mode.). Note that, for
RHEL6.2 and SLES11SP2 and newer, installation through the offload path is
supported. For this case, set the HBA Boot Mode to
Enabled
in the NVRAM
Configuration.
4.
Change the boot order as follows:
a.
Boot from the network adapter.
b.
Boot from the CD/DVD drive.
5.
Reboot the system.
6.
System will connect to iSCSI target, then will boot from CD/DVD drive.
7.
Follow the corresponding OS instructions.
a.
RHEL 5.5—Type
linux dd
at “boot:” prompt and press enter
b.
SuSE 11.X—Choose
installation
and type
withiscsi=1 netsetup=1
at the boot option.
This is intended as a starting set of kernel parameters. Please
consult SLES documentation for a full list of available options.
If driver update is desired, add “
DUD=1
” or choose
YES
for the
F6 driver option.
In some network configurations, if additional time is required for
the network adapters to become active (for example, with a use
of “
netsetup=dhcp,all
”) add “
netwait=8
”. This would allow the
network adapters additional time to complete the driver load and
re-initialization of all interfaces.
8.
At the “networking device” prompt, choose the desired network adapter port
and press
OK
.
9.
At “configure TCP/IP prompt”, configure the way the system acquire IP
address and press
OK
.
10.
If static IP was chosen, you need to enter IP information for iscsi initiator.
