4.9 Dump Environment Setup (Linux: Red Hat)
4.9.2 diskdump initial setting
This section explains the initial settings required for use of the dump function
provided by the distribution.
Because diskdump is included in RHEL-AS4 (IPF), a special installation operation is
not required. Make the following settings after installing RHEL-AS4 (IPF). This
operation requires the root privilege.
The following explains the procedure.
(1) Setting a dump device
Use a text editor such as vi to add the following definition to the diskdump definition
(/etc/sysconfig/diskdump).
Note: Specify the name of a compatible device as the device name.
Remarks:When specifying a dump device list including at least one redundant device,
use a colon (:) to delimit adjacent device names in the list.
DEVICE=device-name (example: DEVICE=/dev/sde1)

Set dump mode
Initialized dump device
