RHBA-2015:1350 - Bug Fix Advisory

Topic

Updated fence-agents packages that fix several bugs and add various enhancements
are now available for Red Hat Enterprise Linux 6.

Description

The fence-agents packages provide a collection of scripts for handling remote
power management for cluster devices. They allow failed or unreachable nodes to
be forcibly restarted and removed from the cluster.

The fence-agents packages have been upgraded to upstream version 4.0.15, which
provides a number of bug fixes and enhancements over the previous version,
including:

• This update adds the "--tls1.0" option to the fence agent for HP Integrated

Lights-Out 2 (iLO2) devices. With this option, iLO2 negotiation of the TLS
protocol works as expected when using an iLO2 device with firmware version 2.27.

• The fence_kdump agent now supports the "monitor" action, making integration

with a cluster stack easier.

• The fence-agents packages now support the fence_ilo_moonshot fence agent for

HP Moonshot iLO devices. For information on the fence_ilo_moonshot parameters,
see the fence_ilo_moonshot(8) man page.

• This update adds support for the fence_ilo_ssh fence agent. The agent logs

into an iLO device using SSH and reboots a specified outlet. For information on
the fence_ilo_ssh parameters, see the fence_ilo_ssh(8) man page.

• This update adds support for the fence_mpath fence agent. This agent is an I/O

fencing agent that uses SCSI-3 persistent reservations to control access to
multipath devices. For information on fence_mpath and its parameters, see the
fence_mpath(8) man page.

• The fence agent for APC devices over Simple Network Management Protocol (SNMP)

has been updated to support the latest versions of the APC firmware.

• This update adds support for the fence_emerson fencing agent for Emerson

devices over Simple Network Management Protocol (SNMP). It is an I/O fencing
agent that can be used with the MPX and MPH2 Emerson devices. For information on
the parameters for the fence_emerson fencing agent, see the fence_emerson(8) man
page.
