scancore(1M) — Series 800 Only

NAME

scancore − scan system core dump

SYNOPSIS

scancore corefile [system]

DESCRIPTION

scancore is used to print information about a crashed system.

In order to use scancore, first obtain an image of the memory of the system after it crashes. This can be done using savecore (see savecore(1M).

scancore reads the relevant system data structures from the core image file and indexing information from /hp-ux (or the specified system file) to determine the scancore information and the state of the processes at the point of the crash. Output consists of the system message buffer, crash information block for each processor in the system, and the process table information. For each process, process table information includes the process table entry values, state of the process, open file descriptors, and the stack trace of the process.

If the corefile is a compacted file (see savecore(1M)), scancore automatically expands the corefile while reading.

WARNINGS

Since scancore operates on kernel data structures, it is not possible to run an old version of scancore on a new release of the operating system or vice-versa. scancore tries to ensure that the corefile, systemfile, and scancore versions match, and if they do not match issues a warning. scancore is likely to behave improperly if operated on mismatching versions of corefile, system, and scancore.
