Support Notes for Red Hat Enterprise Linux ES v.4.5 for HP Integrity Servers

19. The cdrecord program may hang when burning a CD-RW disk with unsupported media
using certain models of CD/DVD-ROM Combo and DVD+RW drives shipped in rx1600,
rx1620, rx2600, rx2620, and rx4640 servers.
Use only approved HP CD-RW media to prevent burn hangs. Try different brands of media
if HP media is not available.
20. System panics may occur on Integrity servers running Linux that have fibre channel (FC)
storage arrays directly connected.
If you plan to connect FC storage to Integrity Servers running Linux, you must connect
through a FC switch. For the BL860c Blade servers, customers must use either the FC switch
module (AE370A/AE371A/AE372A) or an external FC switch.
21. This problem is specific to the LSI1068 SAS I/O controller in the rx2660 and BL860c.
The mpt driver included in RHEL4 does not have the necessary agent components required
by HP System Insight Manager.
To fix this problem, HP has qualified a special version of the mpt driver, which can be
downloaded from the drivers area of www.hp.com .
22. After installing the operating system, if a message similar to the following is displayed, you
will need to take action.
Loading.: Red Hat Enterprise Linux Load of Red Hat Enterprise Linux
failed: Not Found Press any key to continue
To resolve this problem, enter the following commands:
# reconnect -r
# map -r
Then eboot. This can be done by exiting the shell (using the exit command) and reselecting
the EFI boot menu entry.
23. To create a system that can boot either RHEL 4.5 or RHEL 5.0, the RHEL 4.5 system must
be installed and configured before installing the RHEL 5.0 system.
