Half my memory has gone. No not my head, the DL380 G3.

Hello

Check this out
# hpasmcli -s "show server" | grep "Memory installed"
Memory installed : 2048 MBytes

# cat /proc/meminfo | grep MemTotal
MemTotal: 905108 kB

In the RBSU I have selected "Advanced Memory Protection", not "Online
Spare Memory".

Anybody have any ideas how I can use all of my 2G memory?

Regards

# hpasmcli -s "show server" | grep "ROM version"
ROM version : P29 09/15/2004 #which is the latest

# uname -r
2.6.28-gentoo-r5

DL380 G3 is a basic 32-bit x86, so it requires HIGHMEM kernel options in the Linux kernel to go beyond 1GB of memory.

I'm not very familiar with Gentoo Linux, so I'll use the standard Linux kernel terminology and hope you'll know what needs to be done on Gentoo specifically.

If your kernel configuration has CONFIG_NOHIGHMEM set, that's the problem. You should have at least CONFIG_HIGHMEM4G set; if you have only 2G and don't plan on expanding beyond 4G soon, CONFIG_HIGHMEM64G would be overkill.

Thanks for the reply Matti. The kernel options look correct to me:
# CONFIG_NOHIGHMEM is not set
CONFIG_HIGHMEM4G=y
# CONFIG_HIGHMEM64G is not set

No, the above is not quite correct. The problem is with the kernel. Gentoo LiveCD and Knoppix report 2G memory.
