Hello folks, I have two sun blade x6250 servers, one of the server recognized 8G memory and the another server can NOT recognized the 8G memory it just recognized 4G memory. I tried add mem=XG or mem=XXXXM in GRUB.conf but it never work at all and it showed me the following error:
*Command line: ro root=/dev/VolGroup00/LogVol00 rhgb quiet mem=8G* I am not know why option mem not work under RHEL5.1! The BIOS was updated with latest version firmware and they bios are able to recognized the 8G memory in the two servers, but from OS level still one of the servers cannot recognized the 8G only recognized 4G. The kernel version on the both servers 2.6.18-53.el5. Some suggesting I found it on the Internet, to update the kernel to PAE kernel but I am thinking in this solution as the final step to update the kernel. I highly apparacited your advices. Best Regards, Waleed Harbi Success is the sum of small efforts, repeated day in and day out.
