NonStop NS-Series Operations Guide (H06.12+)

NOTE: By default, the CIIN file contains commands needed to start the (permanent) TACL
process pair and to reload all the processors in the system. Do not place commands to prime
the processors in the CIIN file.
Establishing a CIIN File
The CIIN file is configured at the factory as $DSMSCM.SYS.CIIN. You do not need to establish
this file. DSM/SCM automatically copies the CIIN file from the initial location into each SYSnn
you create.
NOTE: The CIIN file must be owned by a member of the super-group (255,n). HP recommends
that you specify “N” for the read access portion of the file security attribute (RWEP) to allow the
file to be read by any user on the network. For example, you might secure this file “NCCC.”
The name of the CIIN file is specified in the INITIAL_COMMAND_FILE entry of the CONFTEXT
configuration file.
A system generation program (run from the DSM/SCM application) copies the file specified in
the CONFTEXT file onto the SYSnn subvolume on the disk and renames the file CIIN. If no file
is specified in CONFEXT, the operating system does not look for the startup file SYSnn.CIIN at
system startup, even if you enable that file. You cannot simply copy a startup file to the SYSnn
subvolume and name it CIIN.
Modifying a CIIN File
After the CIIN file is established on $SYSTEM.SYSnn (as part of running DSM/SCM), you can
modify the contents of SYSnn.CIIN with a text editor such as TEDIT. You need not run DSM/SCM
again to make these changes effective.
If a CIIN File Is Not Specified or Enabled in OSM
The results of the startup TACL process varies depending on whether a CIIN file is specified in
the CONFTEXT file and whether the CIIN option is enabled.

CIIN is executed by initial (startup)
TACL process. Upon completion, this
TACL process terminates. You must
log on to a different TACL process (the
TACL process on $YMIOP.#CLCI
started by the CIIN file) to complete
the system startup process.
EnabledCONFTEXT has CIIN entry, and file

CIIN is executed by initial (startup)
TACL process. Upon completion, this
TACL process terminates, leaving no
TACL process available. You must
reload the system with the CIIN option
disabled in the System Startup dialog
box invoked from the OSM Low-Level
Link; then log on and correct the CIIN
file. Then, either enable the CIIN
option, using the System Startup
dialog box, and reload; or complete the
system startup process manually.
EnabledCONFTEXT has CIIN entry, and file
is available in specified location, but
file is empty or aborts because of
syntax errors before another TACL
process is started.
Initial TACL process is started and left
in logged-off state. You must log on to
complete the system startup process.
