Table 13. Network boot errors (continued) Code Message E3017 (net) TFTP block size negotiation failed Description TFTP server has sent an acknowledgement to the client without block size information for subsequent TFTP network traffic. E3018 (net) file exceeds maximum TFTP The requested file is too big to transfer size transfer via TFTP. Action The TFTP server may not be working properly. Change the TFTP server configuration to allow block size negotiation. Reboot the blade and/or the TFTP server and try again. Change the TFTP server configuration to increase the block size to a maximum value of 1432 bytes. Note: Be aware that your BladeCenter QS21 has two Ethernet controllers and can be connected to two Ethernet switches. As the blade center performs a network boot from the controller that acquires the IP address first make sure that your Linux configuration supports this. If your Linux environment requires a static IP address for a particular Ethernet port, you must set up your DHCP environment accordingly. SAS boot errors These error messages only appear if you have installed the optional SAS daughter card. Table 14. SAS boot errors Code Message E4303 LSISAS1064 controller initialization failed. Description Action The blade server firmware was not Try following steps in order to fix the able to initialize the controller. This problem: could indicate a hardware, blade server 1. Reboot the blade. firmware, or SAS expansion card firmware problem. 2. Power down then remove and reinstall the blade server in the BladeCenter unit. 3. Remove and reinstall the SAS Expansion Card. 4. Ensure the SAS Expansion Card firmware and blade firmware version are at the correct level. 5. If the error started after a SAS Expansion Card firmware upgrade or a blade server firmware upgrade, consider a rollback to the previous firmware versions. Check with the documentation at http://www.ibm.com/systems/ bladecenter/support/ to verify whether rollback is possible. 6. Plug the SAS expansion card into another blade server. If the problem persists, the SAS Expansion Card may need replacement. 7. Plug a different SAS expansion card into the blade server. If the problem persists, the blade server may need replacement.

problem.
Try
following
steps
in
order
to
fix
the
problem:
1.
Reboot
the
blade.
2.
Power
down
then
remove
and
reinstall

firmware
and
blade
firmware
version
are
at
the
correct
level.
5.
If
the
error
started
after
a
SAS
Expansion
Card
firmware
upgrade
or
a
blade
server
firmware
upgrade,
consider
a
rollback
to
the

versions.
Check
with
the
documentation
at

to
verify
whether
rollback
is
possible.
6.
Plug
the
SAS

If
the
problem
persists,
the
SAS
Expansion
Card
may
need
replacement.
7.
Plug
a
different
SAS
expansion
card
into
the
blade
server.
If
the
