7.3 PowerPC productivity tools for SLES

IBM System p servers have some features that are not available on other

platforms supported by SUSE Linux Enterprise Server (SLES). Therefore

software support for these features is not integrated in SLES. IBM provides some

RPM packages collectively called

Service and productivity tools for Linux on

POWER systems

to make full use of the System p hardware.

In addition, they provide some tools for service and support to list and collect

system specific information and error reports. For descriptions, current versions,

and downloads, go to:

http://www14.software.ibm.com/webapp/set2/sas/f/lopdiags/home.html

Some of these tools are necessary for running InfiniBand on SLES. For a list of

some useful optional tools, see Table 7-1.

For users who are familiar with the IBM AIX operating system, most of these

commands are well known.

Table 7-1 Productivity tools

Command RPM package Purpose

bootlist powerpc-utils The bootlist command sets the boot device for next system boot.

Unlike fdisk, this command knows about AIX hdisks.

invscout IBMinvscout The Inventory Scout tool surveys one or more systems for hardware

and software information. The gathered data can be used by Web

services such as the Microcode Discovery Service, which generates a

report indicating if installed microcode needs to be updated.

lscfg lsvpd lscfg lists hardware configuration information for the system and its

components.

lsmcode lsvpd lsmcode lists hardware microcode and firmware levels.

lsvio lsvpd lsvio lists virtual I/O adapters and devices.

See Example 7-8 for a useful output of the lscfg command from the productivity

tools.

Example 7-8 lscfg command output

lib01:~ # lscfg

INSTALLED RESOURCE LIST

The following resources are installed on the machine.

+/- = Added or deleted from Resource List.

* = Diagnostic support not available.

Model Architecture: chrp

Model Implementation: Multiple Processor, PCI Bus

ofpathname powerpc-utils ofpathname provides the ability to translate logical device names to

their Open Firmware device path names for PowerPC-64 systems. It

can also translate an Open Firmware device path to its logical device

name.

log_repair_

action

servicelog The log_repair_action command creates an entry in the error log to

indicate that the device at the specified location code has been

repaired. When viewing a list of platform errors, all errors on the device

at the specified location code prior to the specified date will be

considered closed (fixed).

servicelog servicelog The servicelog command queries and displays the contents of the

system servicelog. Events may be queries by their unique ID in the

servicelog, or by some combination of parameters of the logged

events, as specified by the command-line options.

uesensor powerpc-utils-p

apr

The uesensor utility is used to view the state of environmental sensors

on PowerPC-64 machines.

rtas_errd diagela The Error Log Analysis tool provides automatic analysis and

notification of errors reported by the platform firmware on IBM eServer

pSeries systems. Errors written to /var/log/platform are analyzed. If a

corrective action is required, notification is sent to the Service Focal

Point on the Hardware Management Console (HMC), if so equipped,

or to users subscribed for notification through the file

/etc/diagela/mail_list. The Serviceable Event sent to the Service Focal

Point and listed in the e-mail notification may contain a Service

Request Number.

snap powerpc-utils The snap script copies several system status and config files and the

output of several commands from the system. System servicers may

ask that this be run in order collect data to diagnose a problem.
