Synopsis
New diskdumputils package available
Type/Severity
Product Enhancement Advisory
Topic
A new diskdumputils package that serves as an alternative to the netdump
package is now available.
Description
Due to popular demand, the kernel diskdump facility has been created as an
alternative to the netdump facility, which does not serve all possible
customer configurations.
When diskdumputils is configured and enabled, upon a system crash the
contents of memory will be written to the configured disk location. Upon
system reboot, the data will be copied from the configured disk location
and formatted into a vmcore file. This file is identical in nature to files
created by the netdump facility, and is stored in a unique subdirectory of
/var/crash/. The vmcore file may then be analyzed using the crash(8) utility.
Currently, only x86- and ia64-based systems with SCSI subsystems that use
either the aic7xxx, aic79xx, or mptfusion drivers are supported. In
addition, diskdump requires the dedication of a disk device or partition
large enough to contain all of physical memory. This disk space must be
configured and preformatted before use. After doing so, diskdump can then
be enabled using chkconfig, and the service started.
The kernel modules required for diskdump are included with the Red Hat
Enterprise Linux 3 Update 3 kernel. The associated user-space package is
named diskdumputils, and is the subject of this errata.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains
the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
If up2date fails to connect to Red Hat Network due to SSL
Certificate Errors, you need to install a version of the
up2date client with an updated certificate. The latest version of
up2date is available from the Red Hat FTP site and may also be
downloaded directly from the RHN website:
