StorageTek 6 manual Ssys, Cold, Reset

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.
