7.186. s390utils

Updated s390utils packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The s390utils packages contain a set of user space utilities that should be used together with the zSeries (s390) Linux kernel and device drivers.

Bug Fixes

BZ#1142415
Previously, CPUs could be set online and offline too frequently or not often enough, and, depending on the workload, the default rules in the sysconfig file could lead to an adverse behavior. The default sysconfig file has been updated, and the default rules from the cpluplugd config file now prevent the unwanted behavior from occurring.
BZ#1161726
Prior to this update, the state of zFCP devices was not checked when bringing them online. Consequently, an error occurred for devices that were already online. This update adds an appropriate check, and errors no longer occur in the described situation.
BZ#1186407
Previously, the dasdstat data file with statistics was not seekable. Consequently, the dasdstat tool exited with an error message or reported inconsistent data. With this update, the data file is read without using seeks over the file, and the dasdstat tool prints the correct statistics as expected.
BZ#1223722
Prior to this update, the ziorep tools could not handle device BusIDs "a.b.xxxx" with "a" and "b" being non-zero. As a consequence, the ziorep tools could not parse the ziomon configuration file. All occurrences of device BusIDs in the ziorep tools have been fixed to support a full range of possible values. Now, the ziorep tools can process configuration files that use any valid device BusID.
BZ#1203680
Previously, the Bash syntax for comparison was used by the s390.script, which could lead to errors when a different shell was used. With this update, the correct syntax for value comparison is used, and the s390.sh file is processed correctly by all shells.

Enhancements

BZ#1053824
With this update, the zipl boot loader has been rebased to a later version, which enhances maintainability for Linux initial program load (IPL) code and enables easier inclusion of bug fixes and new features in the boot loader.
BZ#1053828
This update improves the performance of the dasdfmt tool and increases the speed of the Direct Access Storage Device (DASD) formatting process. The kernel internal handling of format requests has been reorganized, and the usage of the Parallel Access Volumes (PAV) feature has been enabled to accelerate format requests.
BZ#1053829
With this update, the verified path mask is shown when listing I/O devices by the lscss tool.
BZ#1148118
This update adds support for Control Unit Initiated Reconfiguration (CUIR), which enables detailed path information for DASD devices to be shown in the lsdasd tool.
BZ#1148126
This update includes switch port attributes in the output of the lsqeth command.
BZ#1148128
This update adds the General Parallel File System (GPFS) as a supported partition type into the fdasd tool. This partition type identifies partitions containing GPFS Network Shared Disks (NSD) used to store GPFS file system information.
BZ#1148744, BZ#1211281, BZ#1211282
The dbinfo.sh tool has been enhanced to allow specifying the directory in which data collection takes place and where the final tar archive is stored. This update also extends the range of information that is collected by including guest networking settings, libvirt, and multipath configurations and logs.
Users of s390utils are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
