A system and method for fast ("warm") reboot of a file server is provided, which skips certain conventional boot processes when circumstances warrant, in order to reduce server downtime. In particular, time is saved by avoiding a full shutdown of the processor and memory, and by causing the firmware to refrain from a full clearance of the file server memory. Instead, the firmware accesses a retained copy of the storage operating system kernel from a reserved location in the file server memory so that an operative version of the kernel is reestablished at the appropriate address space in memory without requiring a time-consuming read of the kernel image from disk. In addition, other "normal" (cold) reboot operations such as full memory tests, hardware checks and memory zeroing are avoided as appropriate-saving further time in the overall reboot process, while still attaining the desired reinitialization of key applications and functions.
