diskdump utility
Hi,
In my DL380 G5 HP Proliant server , i can found that , there is diskdumputility installled
vps211root#rpm -aq |grep diskd
diskdumputils-1.1.9-4
but in /etc/sysconfig/diskdump , it is found that
#
# DEVICE=/dev/sdc8
#
DEVICE=
vps211root#service diskdump status
Device not specified in /etc/sysconfig/diskdump
vps211root#
From these can i confirm that diskdump is not configured in my server.
Also how can i reconfigure this diskdump?

Re: diskdump utility
RedHat documents diskdump configuration in their Knowledge Base (RHN access required):
https://access.redhat.com/kb/docs/DOC-7075
In a nutshell:
- load the diskdump kernel module; it will produce a kernel log message that tells you the required minimum size of the diskdump partition for your hardware configuration.
- create a partition of at least the required size for the diskdump
- edit /etc/sysconfig/diskdump DEVICE= line to point to the partition you created
- run "service diskdump initialformat" to prepare the partition for diskdump (Note: all existing data on that partition will be lost.)
- enable and start the diskdump service
On Proliant hardware + RHEL4, also note this limitation and upgrade your kernel package if necessary:
https://access.redhat.com/kb/docs/DOC-3608
If you are using at least RHEL 4.2 and fulfill the other configuration requirements, you may be able to make your swap partition do double duty as a dump partition:
