Replacing a Gb Ethernet Daughter Card in a Server Module
If you replace a Gb Ethernet daughter card in a server module running the Red Hat Enterprise
Linux (version 3) update 3 operating system, you must assign the new card’s MAC address. Linux
initially creates the
ifcfg-eth
n
file, where
n
is the device ID, based on the original card’s device ID.
If another Gb Ethernet daughter card with a different MAC address is installed, Linux does not
automatically update the file. The MAC address in the
ifcfg-eth
n
file is located in the
hwaddr
line.
GPM-Service Mouse Support
For a mouse to correctly function in the GPM service on a system running the Red Hat Enterprise
Linux (version 3) update 3 operating system, the mouse must be recognized by the operating
system. When using a mouse connected to the KVM, it is possible that the mouse being reported
to the operating system is different than the actual mouse attached. This may result in mouse
movement generating erratic movement or potentially random text on the command line. To
correct this, run
redhat-config-xfree86
to initialize the mouse, and then use
redhat-config-mouse
to install a generic three-button mouse driver for the presently-installed mouse.
Tiered Broadcast Support
If the KVM module is tiered from an external KVM switch to the internal KVM switch, keyboard
and mouse broadcast functionality is not supported. Turn off broadcast to external KVM-switch
ports that have a Dell-integrated KVM switch connected to them.
Installing a Previously-Arrayed Hard Drive Into a SCSI-Mode
Server Module
A hard drive previously installed in a RAID configuration contains partial segments of information
referred to as "meta-data." If you hot-install a hard drive that contains meta-data into a SCSI-mode
server module, its array may appear as degraded after the server module is rebooted.
CAUTION: Do not attempt to rebuild the degraded array in a SCSI-mode server module. The server
module can accommodate up to two hard drives, one of which is the primary physical boot hard drive.
Rebuilding the array could result in loss of data from the primary hard drive.
To remove the meta-data from the replacement hard drive, perform the following steps:
1
Back up all data onto the replacement hard drive.
2
Restart the server module and press <Ctrl><m>.
3
Change the degraded array properties from mirror to SCSI mode by selecting
NO
as the
Mirror
option.
