Abstract

On multi node scalable systems such as the IBM xSeries x440 and x445, it is possible that a single node might fail POST/BIOS execution which would result in the entire partition to fail to boot. Disclosed is a hardware/software solution to allow a partition to recover from such an error to maximize system availability to the end user.
