• Intermittent FTP data truncation when using an HP Procurve 4108gl switch
If you are using an HP Procurve 4108gl switch on a heavily loaded system, you may experience
intermittent data truncation with FTP transfers through the network. This can be avoided with
the following steps:
1. Connect to the HP Procurve 4108gl switch using telnet or serial console, and then login.
2. From the switch command line interface, enter the config command.
3. Enter the no int all lacp command.
• System panics resulting from Fibre Channel storage arrays directly connected to the system
System panics may occur on HP Integrity servers running RHEL when Fibre Channel storage
arrays are directly connected to the system.
If you plan to connect Fibre Channel storage arrays to HP Integrity servers running RHEL, you
must connect through a Fibre Channel switch.
• Correctable hardware events logging configuration
Correctable platform events, such as, single-bit memory errors, are routinely logged into
NVRAM. To ensure errors are logged into the /var/log file, configure the salinfod file
to start at boot.
As root, execute the following:
1. cd /etc/init.d
2. To configure:
chkconfig salinfod on
3. To start salinfod without rebooting:
service salinfod start
• Contiguous memory unavailable on cell-based server causing an MCA
When Linux boots on an HP Integrity mid-range or high-end cellular server with discontiguous
memory, a cell may boot to a state in which it has too little contiguous memory available and
could cause an MCA.
