DESCRIPTION

The kgcore command is used to make a copy of the kernel memory image of a Sprite machine. The memory image may be used with kgdb to examine the machine’s state. Machine is the name of a machine running Sprite. The machine must be in the kernel debugger for kgcore to work (see the -d option of the kmsg command.) Kgcore writes the kernel memory image to the file vmcore unless another file name is specified with the −o option. This file may be specified as a core image to kgdb.
