RHBA-2013:1018 - Bug Fix Advisory

Topic

Updated openhpi packages that fix several bugs are now available for Red Hat
Enterprise Linux 6.

Description

OpenHPI provides an open source implementation of the Service Availability Forum
(SAF) Hardware Platform Interface (HPI). HPI is an abstracted interface for
managing computer hardware, typically chassis- and rack-based servers. HPI
includes resource modeling; access to and control over sensor, control,
watchdog, and inventory data associated with resources; abstracted System Event
Log interfaces; hardware events and alarms; and a managed hot swap interface.

This update fixes the following bugs:

• Due to missing support for certain thermal sensors, the getBladeInfo()

function terminated, making the whole discovery process fail. This update adds
the support for these sensors and OpenHPI discovery now works as expected.
(BZ#969006)

• Previously, code supporting certain RDR sensors was missing in OpenHPI.

Consequently, after the extraction and reinsertion of an enclosure monitored via
the Onboard Administrator (OA) SOAP plug-in, the following error messages were
returned to the log file:

openhpid: ERROR: (oa_soap_sensor.c, 2005, RDR not present)
openhpid: ERROR: (oa_soap_fan_event.c, 279, processing the sensor event for
sensor 24 has failed)

This bug has been fixed and no error messages are now logged after a component
is extracted and reinserted. (BZ#969003)

• Prior to this update, support for certain blade servers was missing in

OpenHPI. Consequently, the OpenHPI daemon terminated unexpectedly with a
segmentation fault as startup on these servers. A patch has been provided to add
the missing support and the OpenHPI daemon no longer crashes in the described
scenario. (BZ#969005)

• Under certain conditions, when using OpenHPI with the Onboard Administrator

(OA) SOAP plug-in when an OA switch-over took place, HPI clients became
unresponsive or the openhpi daemon failed to connect to the new active OA.
Consequently, clients were unable to retrieve events and data. A series of
patches has been provided to better account for OA failover situations, thus
fixing this bug. (BZ#969004)

• Due to a bug in the power_supply() parsing routines, some returned strings

could contain incorrectly displayed characters. Consequently, retrieving a
serial or part number of a power supply unit (PSU) via the OpenHPI API resulted
in strings containing these characters. This update ensures that proper serial
and part numbers are returned for PSUs and the returned strings now only contain
valid characters. (BZ#915336)

Users of openhpi are advised to upgrade to these updated packages, which fix
these bugs.

Solution

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.
