RHEA-2011:1562 - powerpc-utils bug fix and enhancement update

Synopsis

powerpc-utils bug fix and enhancement update

Type/Severity

Product Enhancement Advisory (none)

Topic

An updated powerpc-utils package that fixes several bugs and adds various enhancements is now available for Red Hat Enterprise Linux 6.

Description

The powerpc-utils package provides various utilities for a PowerPC platform.

The powerpc-utils package has been upgraded to upstream version 1.2.10, which provides a number of bug fixes and enhancements over the previous version. The powerpc-utils package now provides the following new features:

  • The page coalescing feature that provides the ability to share identical pages in physical memory among multiple logical partitions. Identical pages are consolidated into one shared read-only copy, and expanded into individual copies if an individual partition change occurs. (BZ#694541)

  • The lparstat tool that provides the ability to display various attributes of IBM Power Logical Partitions, such as CPU and memory entitlement and other similar attributes. (BZ#632705)

In addition, this update fixes the following three bugs:

  • When removing memory from logical partition (LPAR) in Dynamic Logical Partitioning (DLPAR), the dynamic memory manager (drmgr) did not set the memory off-line correctly. As a consequence, the kernel of the LPAR panicked. This update corrects the code so that drmgr now sets memory off-line properly, and the kernel no longer crashes when removing memory in DLPAR. (BZ#698433)

  • The drmgr(8) manual page contained obsolete information that drmgr is a part of the ppc64-utils suite. This has been corrected, and the manual page now states that drmgr is a part of the powerpc-utils suite. (BZ#739888)

  • The ofpathname script was not able to convert the Open Firmware device path name to the logical device name for SAN disks. With this update, ofpathname converts path names to device names correctly. (BZ#739957)

All users of powerpc-utils are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.
