Adding second CPU
I have installed a second XEON 2.40GHz processor (and a VRM) on a Fujitsu Siemens Server. Now the system has two identical CPUs.
Both CPUs are detected in the BIOS. However Linux is only seeing one CPU (cat /proc/cpuinfo). Is it because I'm running the non SMP version of the kernel? I'm using Red Hat Enterprise Linux.
Yes, you need to install the SMP kernel in order for the second CPU to be seen. With RHEL it is pretty darned simple to install the SMP kernel, fortunately.
Ah! The qla2300. If you are having trouble getting the generic qla drivers to work that come from Redhat, you might try compiling the drivers from qlogic. In case you did not know, the redhat drivers for the qla2300 are not fully functional, so options such as failover and load balancing are not enabled at all with them.
Granted, configuring load balancing on the qla2300 is no easy task. It sucks. If you need more details on the procedure for getting load balancing to work with a qla2300, let me know and I will detail it in full.
