dumpsave, ldsysdump --
save or restore a system memory image dump
calls dumpsave (provided that the system has not autobooted)
to copy a system memory image dump from the swap area to tape or floppy
The dump may be subsequently analyzed using
to discover the cause of the kernel panic that produced the dump.
You can force a dump to be written to tape instead of the swap
area by editing the dump entry in the
/etc/conf/cf.d/sassign file (see
or by using the dump bootstring (see
ldsysdump is used to copy a dump from
tape or floppy disk to a file (dumpfile).
dumpsave and ldsysdump prompt for the
floppy drive number (the default is /dev/rfd0)
and type, or tape device to be used.
A dump is of no value unless a copy of the executable kernel that
produced it is also available (this is needed for its symbol table).
For certain investigations, the fileystems in use at the time of
the kernel panic should also be saved. This enables filenames to be
associated with the inodes that processes had opened.
