Netserver_lh4
Contents |
Introduction
The HP Netserver LH4 server made in the late 1990s. It featured dual, and quad Pentium III Xeon configurations, and up to 4 gigabytes of ram spread across 16 100MHz EDO banks. It can be mounted in a rack, or set up as a standing unit on wheels. It holds up to 12 SCSI disks in swapable trays, backed by an LSI MegaRAID controller.
Installation Tips
Some of the older live CDs may have problems booting on this server, this is because they're loading the wrong MegaRAID driver. The correct driver is know as MEGARAID_LEGACY. Without this module loaded, you will not be able to access your RAID array.
Gentoo Configuration
I will spare you the details of the other new hardware I have installed in my LH4, and just stick with what's needed to make it work.
| File: cat /etc/make.conf |
# Please consult /etc/make.conf.example for a more detailed example
CFLAGS="-O2 -march=i686 -pipe"
CHOST="i686-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"
MAKEOPTS="-j5"
USE="mmx sse nptl nptlonly smp"

Memory (RAM)
A minimum of 4 64MB modules are required for operation, and a maximum of 16 256 modules can be installed. Memory must be installed in matching pairs of 4. When installing new memory, you will notice two trays, each with 2 sets of banks. You need to put one module in each bank. Installing 4 memory modules in 1 bank will cause the machine to fail when booting, or show incorrect memory sizes.
SCSI Card
The SCSI card can be set to use the following RAID configurations RAID 0, RAID 1, RAID 3, RAID 5, RAID 10, RAID 30, RAID 50. It connects to two drive cages in the front of the machine, each capable of holding 6 SCSI disks.

Onboard ATA
This machine comes with an ATA CDROM drive. The driver for the ATA controller is PIIX4.
