What If; Self-Loading Emergency Dump - Sled - Fujitsu Siemens Computers SX series User Manual

12 What if ...

This chapter describes what to do if a fault occurs at the system unit. It helps you to detect
faults, identify their causes and, in some cases, to eliminate such malfunctions immediately.
In the case of faults that can only be rectified by service staff, you can perform a preliminary
diagnosis and then contact the service staff for further information.
Depending on the response of the service staff, you may be able to resume system
operation.
The following aids for solving problems are described below:

12.1 Self-Loading Emergency Dump - SLED
If an error occurs then a self-loading emergency dump of the system unit saves the
processor information present in RAM for subsequent diagnostic operations. The BS2000
program SLED saves the error information to the hard disk or to tape for subsequent evalu-
ation by the service staff. During this process, an IOH dump and an IOS dump are also
created (for further information, see
The self-loading emergency dump can be performed automatically if the BS2000 operating
system has been suitably prepared (see the "BS2000/OSD-BC Introductory Guide to
Systems Support" [12]).
The self-loading emergency dump is performed once the dipl command has been issued.
The message NSD3000 asks you to specify the SLED output device. The diagnostic file
(SLEDFILE) that is created contains all the data which is required for subsequent evaluation
by the service staff.
Following a self-loading emergency dump, the system unit should generally be re-initialized
by means of an ipl.
