Purpose

 This document will explain how to get the ereport information available through ALOM (alom4v).

Troubleshooting Steps

Steps to Follow

By design, there will be two logs that store ereports on DOC (diskonchip)
of the 	Service Processor:

/scfs/fma/ereports/ereports.firstlog.
/scfs/fma/ereports/ereports.lastlog

Both log files have a maximum size of 2 MB. The first log will capture the first N ereports sent from VBSC to ALOM. When the first log fills up, the successive ereports will be logged in the second log. The second log is implemented as a circle buffer. In this way, the users can always see the first N and the last N ereports that have occurred.

The commands to display ereport logs are:

showfmerptlog1 [-e [hexformatena]] [-p [pauseline]] [-v]
showfmerptlog2 [-e [hexformatena]] [-p [pauseline]] [-v]

The syntax rule for 'showfmerptlog1' and 'showfmerptlog2' are as below:

1. Without any option, the command will display all the ereports in the log without pausing.

2. The zero value of 'pauseline' means no pause.

3. If no 'pauseline' provided, but '-p' is set, the default value of the 'pauseline' is 25.

4. If no 'ena' is provided, but '-e' is set, the command will only display ENA and class for each ereport in the log.

5. If both 'ena' and '-e' are set, the command will only display the full content of the specific ereport that matches the 'ena' value.

6. The '-v' option increases levels of detail. This isn't valid/needed if '-e'/'ena' is set.

To clear all the ereport logs, use the command:
clearereports

The 'clearereports' command will clear both ereports stored on DOC and ereports stored in RAM. Therefore, after the clear command, the previous ereports at ALOM will not be sent to host domain any more.

There will be another two files that store information about faults on DOC:

/scfs/fma/faults/faults.current
/scfs/fma/faults/faults.history

The commands to display information about faults are:

showfmfaults [-u [uuid]] [-p [pauseline]] [-v]
showfmlogs [-u [uuid]] [-p [pauseline]] [-v]

Where 'showfmfaults' shows only information about the current FMA fault events. And 'showfmlogs' shows information on all current and history (already cleared) FMA fault events.

All five commands are hidden under sc_servicemode:

Use 'setsc sc_servicemode true' / 'setsc sc_servicemode false'
to enable / disable sc_servicemode.

Example:
========
sc> setsc sc_servicemode true
