HP Integrity NonStop H-Series - Manual (Page 233)

D Required Processes and Files
This appendix describes the contents of the $SYSTEM, $DSMSCM, and $AUDIT disk volumes, as
preconfigured on all NonStop S-series servers and Integrity NonStop servers. DSM/SCM requires
these permanent and temporary files to function correctly. Do not purge or alter subvolumes or
files as noted. Doing so can cause serious performance problems and might require a reinitialization
of DSM/SCM.
