Elevators
Elevators
are considered pass-thru ports. Each elevator has three pass-thru
operations per rail. Each rail can pass-thru to the other three rails.
Operational Differences
LSM Prefencing:
Is basically the same as with other libraries and tries to minimize pass-thru
operations (elevator, turntable, and pass-thru ports).
•
Mount scratch tapes — Selects cartridges based on the LSM (rail)
•
Query mount — Orders drives by LSM (rail) proximity
•
Query mount scratch — Orders drives by LSM (rail) proximity
•
Enter — Enters cartridge from the CAP to the closest LSM with free Slots
Limits:
•
The maximum number of panels in a library is 60.
Mount
and
Dismount Commands:
You or CSC can still specify a cartridge by VOLID or VOLSER and specific
drive location. If a cartridge move using a pass-thru operation (elevator) the
default behavior is for that cartridge to remain in the drive’s LSM.
Enter
(Import)
and
Eject
(Export)
Commands:
Library management software normally tries to
Enter/Import
a cartridge to an
LSM (rail) adjacent to the CAP.
Currently with
ELS/HSC
, if there are open slots in the top LSM (00), an
Enter
command attempts to place the cartridge in that LSM (00), then work its way
down. For example: If a cartridge is entered in the second magazine of a CAP,
and there are open slots in LSM 0, the library performs a pass-thru operation
with the elevator from the CAP to LSM 0.
For an
Eject/Export
command, the software ejects the cartridge to the CAP
magazine adjacent to the LSM. For an
Eject/Export
command from LSM 0,
the library performs a pass-thru operation to an open slot in the top magazine
of the CAP.

Host Software Component
The StorageTek Host Software Component (HSC) is one type of management
software that can control the SL8500 library. This software resides in the host
but is transparent to the operating system.
HSC receives requests from the programmatic interface and translates them
into commands that are carried by the control path to the LSM.
The Storage Management Component (SMC) also resides on the MVS host
along with HSC and communicates to:
