Step 2. Multiply the number of pages listed in "Total pages included in
dump" by the page size (4 Kbytes) and add 25% for a margin of safety. In
the above example, the calculation would be:
(6208 x 4 Kbytes) x 1.25 = approx. 30 Mbytes
Kernel dump device definitions
Capturing dumps for crashes that occur during early stages of the boot
process requires sufficient dump space in the kernel configuration.
Using SAM to configure dump devices into the kernel
The easiest way to configure dump devices is to use SAM. A screen for
dump device definition is located in the Kernel Configuration area. After
changing the dump device definitions, you must build a new kernel and
reboot the system using the new kernel file to make the changes take
effect. To configure dump devices into the kernel, perform the following
procedure:
Step 1. Run SAM and select the Kernel Configuration Area
Step 2. From the Kernel Configuration Area, select the Dump Devices area
A list of dump devices configured into the next kernel built by SAM is
displayed. This is the list of pending dump devices.
