Support Notes for Red Hat Enterprise Linux AS v.2.1 for the Itanium Processor on HP Integrity Servers

Support Note for Red Hat Enterprise Linux AS v.2.1 for the Itanium® Processor on HP Integrity Servers
Known Problems
Chapter 1 21
c. When etc/fstab is configured to automatically NFS mount on the network accessed
by the HP A7061A NIC referenced in Step b.
Intialization of the HP A7061A NIC can take up to 30 seconds longer than the system
startup script for networking reports. The network appears to be up but isn’t due to an
issue with the tg3 driver. To workaround the problem, run:
ifdown eth<N>; ifup eth<N>; mount server:remotepath localpath
where <N> is the appropriate number for the HP A7061A NIC.
9. Pressing the
F1 key in a text mode installation causes the installation to abort unless
using Update 3 or later. Though the
F1 key should access Help, do not use it if installing in
text mode with Red Hat Enterprise Linux AS v.2.1 Update 2 or earlier.
To update your operating system, use the instructions in “Registering Software and
Getting Updates from Red Hat Network” on page 16.
10. On HP Integrity rx2600 servers, simultaneous sustained data transfer from the CD Rom
drive and through networking devices can result in packet loss on the network.
This problem occurs because Direct Memory Access (DMA) is not enabled on the CD Rom
drive. You can run hdparm -d1 /dev/cdrom to enable DMA on the CD drive; however,
doing so can cause machine check aborts (MCAs).
11. Inconsistencies with man page directions for editing /etc/fstab.
If you manually edit the /etc/fstab file to alter the device partition to be mounted as
swap space, follow the fstab man page directions. The swapon manpages incorrectly
describe swap filesystem entries in /etc/fstab as being labeled with"sw" when they
should be labeled "swap". swapon will not throw an error if it encounters an invalid swap
entry in /etc/fstab.
