NAME

snapcopy − copy VAX 8600/8650 snapshot files

SYNTAX

/etc/snapcopy directory

DESCRIPTION

When the system crashes on a VAX 8600 or VAX 8650 system, the console subsystem creates “snapshot files” containing binary information regarding the state of the hardware at the time of the crash.  Snapshot files are typically used by hardware maintenance personnel to analyze and repair the cause of the system crash. 

The snapcopy command copies any valid snapshot files (called snap1.dat and snap2.dat) from the console RL02 disk into the directory specified.  The files are renamed to show the time of the copy:

hr:min:sec-snap1.dat
hr:min:sec-snap2.dat

The files are then invalidated on the console RL02 disk, meaning that they can be rewritten by the console subsystem in the event of another system crash. 

You should delete the comment character for the snapcopy command in the /etc/rc.local file only for VAX 8600 and VAX 8650 systems.

The directory is the name of the directory to which the snapshot files are to be copied. 

DIAGNOSTICS

snapcopy:  not a directory
snapcopy:  no write permission for directory
snapcopy:  could not chdir to directory

The directory must exist and be writable. 

FILES

/dev/ttyc3Special file by which snapcopy communicates with the system console terminal

/dev/crlSpecial file by which snapcopy communicates with the console RL02 disk

/etc/rc.localFile that contains site-specific commands to be executed when the ULTRIX system is brought to multi-user mode
