Cluster Manager Update

The Cluster Manager utility (cman) has been updated to version 2.0.97. This applies several bug

fixes and enhancements, most notably:

• cman now uses the following firmware versions: APC AOS v3.5.7 and APC rpdu v3.5.6. This

fixes a bug that prevented the APC 7901 from using simple network management protocol

(SNMP) properly.

• fence_drac, fence_ilo, fence_egenera, and fence_bladecenter agents now support

ssh.

• fence_xvmd key files can now be reloaded without restarting.

• A single fence method can now support up to 8 fence devices.

RPM Re-Base

The RedHat Package Manager (RPM) is now re-based to the Fedora 9 upstream version. rpm

now adds secondary architecture-specific macro files on multi-arch systems. In addition, rpm now

meets all certification criteria for inclusion in Red Hat Enterprise Linux 5.

This update also applies several upstream enhancements and bug fixes to rpm, including:

• rpm no longer generates unnecessary .rpmnew and .rpmsave files on multi-arch systems.

• A bug in the rpmgiNext() function of rpm prevented proper error reporting. This update

applies the proper semantics for error reporting, thereby ensuring that rpm returns the correct

exit code in all instances.

Open Fabrics Enterprise Distribution (OFED) / opensm

opensm has been updated to the upstream version 3.2, including a minor change to the opensm

library API.

• The format of the opensm.conf file has changed. If you have made custom modifications to

your existing opensm.conf, rpm will automatically install the new opensm.conf file as /etc/

ofed/opensm.conf.rpmnew. You will need to migrate your modifications to this file and then

replace the existing opensm.conf file with the result.

• Red Hat closely tracks the upstream Open Fabrics Enterprise Distribution (OFED) code

base in order to provide a maximal level of enablement for this still evolving technology. As a

consequence, Red Hat can only preserve API/ABI compatibility across minor releases to the

degree that the upstream project does. This is an exception from the general practice in the

development of Red Hat Enterprise Linux.

Because of this, applications build on top of the OFED stack (listed below), might require

recompilation or even source-level code changes when moving from one minor release of Red

Hat Enterprise Linux to a newer one.

This generally is not required for other applications, built on the Red Hat Enterprise Linux

software stack. The components affected are:

• dapl

• compat-dapl
