158 VM/HSC 6.0 System Programmer’s Guide
1st ed., 6/30/04 - 312579601
SSYS
specifies that HSC initialization search for the subsystem name specified. If SSYS is
specified, the name must match the LIBSUBSYS parameter value in the system
profile (SYSPROF). If the name is not found or is not a valid name, the subsystem
terminates. subsystem must be a 1- to 4-character name or problems can occur when
initializing the HSC.
This parameter permits you to symbolically specify the subsystem if the job name in
the startup SLKJCL file does not match the subsystem name.
Note: Either the job name or the SSYS value must match the subsystem name or the
HSC will not initialize.
COLD
specifies that any permanent in-memory data structures previously allocated by HSC
are reallocated and reinitialized.
On the first startup of the HSC after an IPL, this option is meaningless.
This parameter should be used only when absolutely necessary. (The installation
instructions for some HSC maintenance may direct you to perform a COLD start.)
Note: You do not need to include the COLD parameter when you are initializing an
HSC that is at a different release level than the HSC that was previously running on a
host. When an initializing HSC detects a release level difference, it performs an
automatic internal cold start.
Contact StorageTek Software Support before using this parameter (see the guide
Requesting Help from Software Support for more information).
RESET
specifies that all subsystem status flags in the Subsystem Communications Vector
Table (SSCVT) for the HSC are unconditionally reset. Use of this option may correct
a situation in which the HSC was terminated abnormally without resetting the status
flags.
One possible symptom of this situation is the message:
... ACS subsystem CCCC is ACTIVE
or
... ACS subsystem CCCC is TERMINATING
or
... ACS subsystem CCCC is INITIALIZING
at HSC startup, when a display of active jobs indicates that the subsystem is not, in
fact, active.
