Saving Memory Dumps
5-48 Fault Tolerant System Administration (R1004H) HP-UX version 11.00.03
NOTE
The order of the devices in the list is important. Directories are used in
reverse order from the way they appear in the list. The last device in the
list is used as the first dump device.
4. Follow the SAM procedure for building a new kernel.
5. When the time is appropriate, boot your system from the new kernel file to
activate your new dump device definitions.
Using Commands to Configure a Dump Device
You can also edit your system file and use the config program to build your new
kernel.
1. Edit your system file (the file that config will use to build your new kernel).
This file is usually the file /stand/system, but can be another file if you
prefer.
– If you want to dump to a hardware device, for each hardware dump
device you want to configure into the kernel, add a dump statement in the
area of the file designated * Kernel Device info (immediately prior
to any tunable parameter definitions). For example: dump 2/0/1.5.0 or
dump 56/52.3.0
NOTE
For systems that boot with LVM, either dump lvol or dump none must
be present. Without one of these, any dump hardware_path statements
are ignored.
– If you want to dump to a logical volume, it is unnecessary to define each
volume that you want to use as a dump device. If you want to dump to
logical volumes, each logical volume to be used as a dump device must be
part of the root volume group (vg00) and contiguous (no disk striping, or
bad-block reallocation is permitted for dump logical volumes). The logical
volume cannot be used for file system storage, because the whole logical
volume will be used. To use logical volumes for dump devices (regardless
of how many logical volumes you want to use), include the following
dump statement in the system file:
dump lvol
