Lenovo NeXtScale n1200, Installation And Service Manual

Page: 77 / 878

If the server is not hung and the IMM2.1 is connected to a network, methods are available for you to view one
or more event logs without having to restart the server.
If you have installed Dynamic System Analysis (DSA) Portable, you can use it to view the system-event log
(as the IPMI event log), or the IMM2.1 event log (as the ASM event log), the operating-system event logs, or
the merged DSA log. You can also use DSA Preboot to view these logs, although you must restart the server
to use DSA Preboot. To install DSA Portable or check for and download a later version of DSA Preboot CD
image, go to https://support.lenovo.com/us/ en/documents/LNVO-DSA.
If IPMItool is installed in the server, you can use it to view the system-event log. Most recent versions of the
Linux operating system come with a current version of IPMItool. For an overview of IPMI, go to http://www.
ibm.com/developerworks/linux/blueprints/ and click
Using Intelligent Platform Management Interface
(IPMI) on Lenovo Linux platforms .
You can view the IMM2.1 event log through the Event Log link in the Integrated Management Module 2.1
(IMM2.1) web interface. For more information, see “Logging on to the web interface” on page 43.
The following table describes the methods that you can use to view the event logs, depending on the
condition of the server. The first three conditions generally do not require that you restart the server.
