SHOW CRASH
SHOW CRASH
In the analysis of a system failure, displays information about the state of the
system at the time of the failure. In the analysis of a running system, provides
information identifying the system.
Format
SHOW CRASH
Parameters
None.
Qualifiers
None.
Description
The SHOW CRASH command has two different manifestations, depending upon
whether you use it while analyzing a running system or a system failure.
In either case, if the SDA current CPU context is not that of the processor that
signaled the bugcheck, the SHOW CRASH command performs an implicit SET
CPU command to make that processor the SDA current CPU. (See the description
of the SET CPU command and Section 4 for a discussion of how this can affect
the CPU context—and process context—in which SDA commands execute.)
When used during the analysis of a running system, the SHOW CRASH command
produces a display that describes the system and the version of OpenVMS that
it is running. The system crash information display contains the following
information:
• Date and time that the ANALYZE/SYSTEM command was issued (titled
‘‘Time of system crash’’ in the display)
• Name and version number of the operating system
• Major and minor IDs of the operating system
• Identity of the system, including an indication of its VAXcluster membership
• CPU ID of the primary CPU
• Two bit masks indicating which processors in the system are active and which
are available for booting, respectively
When used during the analysis of a system failure, the SHOW CRASH command
produces several displays that identify the system and describe its state at the
time of the failure.
The system crash information display in this context provides the following
information:
• Date and time of the system crash.
• Name and version number of the operating system.
• Major and minor IDs of the operating system.
