Chapter 1. Purpose

This SUSE Linux Enterprise Server 10 Service Pack 2 serves several purposes:

• Provide enhancements to the SLES 10 code base (see Chapter 2, New Features).

• Provide all maintenance fixes (see Chapter 3, Driver Updates) released since GA of SLES 10.

• Provide an easy update (see README) of your system or individual packages to the latest Service Pack

level. This is especially useful if you cannot use online update mechanisms.

• Provide an easy fresh install (see README) using the latest kernel, drivers, and installer updates.

• Include PTFs (special fixes for customers) which were folded back into the SLES 10 common code

base making them part of the maintained code base.

• Provide useful additional information and documentation (see Chapter 5, Installation-Related Notes).

Through joint testing and maximum care, we try hard not to break any ISV certification with a Service

Pack, but we recommend checking with your ISV about your application's certification status.

With the release of SUSE Linux Enterprise Server 10 Service Pack 2, the now obsoleted Service Pack 1

enters limited support status for the following 6 months, during which time Novell will continue to provide

security updates and L3 support to maintain its customer's operations safe during the migration window.

At the end of the six-month parallel support period, on November, 15th 2008, support for Service Pack

1 will be permanently discontinued.

VMI interface layer is part of the package kernel-vmi which is available as x86 package only (not for

x86_64). This package can be installed via your favorite update tool once the system has a registered

update channel.

Asymmetric LUN Access or T10 ALUA) was added.

• Support for Autofs version 5 was added additional to the standard version 4.

• SuSEfirewall2 now autodetect bridge interfaces and permit traffic.

• zSeries: AF_IUCV Protocol Support: Enables IUCV communication via the BSD socket interface

between Linux VM guests or between a Linux guest and CMS. More info: Device Drivers, Features,

and Commands - SC33-8289-04, Chapter 21. AF_IUCV protocol support.

• zSeries: Kernel NSS support: Saves memory when running multiple Linux server with the same kernel

under z/VM by allowing to save the kernel in a Named Saved Segment in z/VM. More info: Device

Drivers, Features, and Commands - SC33-8289-04, Chapter 13. Shared kernel support.

• zSeries: ETR (external time reference) Support: Enables Linux images to synchronize with parallel

Sysplex or GDPS by providing z/OS compatible external timer reference and maintaining data

consistencygroupsforXRCdatamover.Moreinfo:TheETRsupportintroducesanewkernelparameter

"etr"thatisusedtosettheinitial state for theonlineattributeof the two ports.Thesyntaxof the parameter

is "etr=[on | off | port0 | port1]". The default is "off". The ETR support introduces a number of sysfs-

New Features

attributes. There are two time synchronization ports etr0 and etr1, which can be accessed via sysfs under:

/sys/devices/system/etr

• zSeries: Dynamic CHPID reconfiguration via SCLP: Allows to react to hardware changes and to

configure path for the LPAR from the Linux system. More info: Device Drivers, Features, and

Commands - SC33-8289-04, Chapter 2, Configuring a CHPID on LPAR and Chapter 32, chchp and

lschp.

reliability (avoid memory allocation failures in network subsystem) with large MTU sizes and jumbo

frames. In particular this renders HiperSockets highly available even for large messages.

• zSeries: FCP performance data collection - adapter statistics: Provides more hardware performance

metrics which are available from the FCP adapter on IBM System z9 and z10.

• zSeries: Support for Processor Degradation: Generates uevents for all CPUs if the CPU-capability

changes. This can happen e.g. because the CPUs are overheating. The CPU-capability can be read via:

/sys/devices/system/cpu/cpuN/capability. More info: Device Drivers, Features, and

Commands - SC33-8289-04, Chapter 2, CPU capability change.

useful for tasks like preparing the z/VM reader from Linux to install or to dump to the z/VM reader.

More info: Device Drivers, Features, and Commands - SC33-8289-04, Chapter 18. z/VM unit record

device driver.

• zSeries: STSI change for capacity provisioning: Make the permanent and temporary capacity

information as provided by the STSI instruction of the IBM System z10 available to user space via

/proc/sysinfo.

• zSeries: Hotplug daemon for CPU and memory management: New daemon in s390-tools 1.6.3 that

manages CPU- and memory-resources based on a set of rules. Depending on the workload CPUs can be

enabled or disabled. The amount of memory can be increased or decreased exploiting the Cooperative

Memory Management (CMM1) feature. See: man -a cpuplugd. More info: Device Drivers, Features,

and Commands - SC33-8411-00, Chapters 36 (cpuplugd - Activate CPUs and control memory Use).

• zSeries: HiperSockets MAC layer routing support: Enables Layer-2 support in HiperSockets, including

IPv6 for Layer-2, on the new z10 hardware. Note that connecting Layer-2 and Layer-3 hosts is not

supported. To use it, echo 1 > layer2 attribute before setting the HiperSockets device online.

• zSeries: Support two OSA ports per CHPID: Exploits the next OSA adapter generation offering two

ports within one CHPID, giving you four ports per card ("Four-port exploitation on OSA-Express3 GbE

SX and LX"). The additional port number 1 can be specified with the qeth sysfs-attribute "portno". More

info: Device Drivers, Features, and Commands - SC33-8411-00, Chapters 9 (Specifying the relative

port number).

optimal node where the CPU is associated, exploiting the new z10 CPU node topology. More info:

Device Drivers, Features, and Commands - SC33-8411-00, Chapters 2 (Examining the CPU topology).

New Features

• zSeries: Large Page Support: Enables better system performance with large memory footprints like in

Java or database workloads by exploiting the new z10 hardware feature to be able to use large memory

pages (1 MB). See: Linux kernel source tree under Documentation/vm/hugetlbpage.txt. More info:

Device Drivers, Features, and Commands - SC33-8411-00, Chapters 28.
