Abstract
A processor, executing a first operating system kernel, tags a region of volatile memory used by a first storage area network (SAN) adapter driver coupled to a SAN adapter, and decouples the first SAN adapter driver from the SAN adapter. A boot of a second operating system kernel is then initiated while preserving in the tagged region of the volatile memory contents stored therein. After the boot, a second SAN adapter driver is then coupled to the SAN adapter.
