Diagnosing RTAS events
You can install and use the ppc64-diag, libservicelog, servicelog, and powerpc-utils packages to diagnose RTAS (Run Time Abstraction Services) events.
RTAS events (also known as platform events) might occur while your system is booting or running. RTAS events might be logged in the following places:
- The console and the kernel ring buffer
- The servicelog database
- The /var/log/platform file
Displaying RTAS events in the kernel ring buffer
The kernel displays RTAS events in the console, and captures them in the kernel ring buffer. To display the kernel ring buffer, run the following command:
# dmesgThe following example shows RTAS events that are reported in the console and kernel ring buffer:
RTAS: event: 2340, Type: Platform Error, Severity: 2
RTAS: event: 2341, Type: Dump Notification Event, Severity: 1The event numbers displayed as 2340 and 2341 in the example identify events on your system. They have no diagnostic meaning.
Displaying RTAS events in the servicelog database
The ppc64-diag package includes the rtas_errd daemon, which logs RTAS events to the servicelog database with the libservicelog package. The servicelog package provides commands for viewing the database. Install each package. See Platform diagnostics (ppc64-diag) and servicelog for information about these packages.
You can display a summary of servicelog events to determine whether any RTAS events are saved to the servicelog database. To display the summary, run the following command:
servicelogThe following sample output shows that there are 5 RTAS events:
Servicelog Statistics:
There are 3 open events requiring action.
Summary of Logged Events:

Registered Notification Tools: 3To display the servicelog database, run the following command:
# servicelog --dump
The following sample output shows an example of an RTAS event in the servicelog database:

Platform Firmware Informational (non-error) Event. Refer to the system
service documentation for more information.

bytes): /var/log/dump/FSPDUMP.108B7AA.AA000000.20120727044812
For information associated with the reference code in an RTAS event logged in servicelog, search for the reference code in Knowledge center.
Displaying RTAS events logged in the /var/log/platform file
Install the powerpc-utils package, which provides the rtas_dump command. See Service aids for information about the package.
You can display the RTAS events logged in the /var/log/platform file in two ways:
- View the file in a text editor. The events display without formatting.
- Run the rtas_dump command to display the events with formatting. For
example:
rtas_dump -f /var/log/platformThe following sample output shows several RTAS events logged in the /var/log/platform file:
