Row
Within each LSM (rail) rows are numbered consecutively from the top down. These
start with 1 for the SL8500 and 0 for host.
Column
SL8500 column numbers are referenced from the customer interface module, where +1
is right of the center of the drive bays and -1 is to the left of the drive bays. The host
software reports two columns for each cell storage panel (column 0 and 1)
CAP
The CAP behavior controlled by host software is as follows:
The CAPs service all the LSMs in the library.
CAPs span across three LSMs (1-3).
Each CAP has three magazines with 13 slots each. Each magazine is adjacent to a
separate rail, and can only be accessed by robots on that rail. There is no adjacent
section in the CAP for the top LSM (0), which requires pass-thru operations with the
elevator.
When loading cartridges in the CAP, slots can be skipped or magazines missing.
There is no adjacent magazine section in the CAP for rail 1 (LSM 0), which requires
pass-thru operations with the elevator.
The CAP is treated as an independent component, and does not belong to any one
rail.
Examples of CAP Behavior:
A CAP can be online and operational even though the LSM (rail) identified in the
CAP ID is offline or not operational.
If an LSM is offline, the associated CAPs are not automatically offline.
If an LSM is online, the associated CAP is not automatically placed online.
Even if LSMs 1 through 3 are offline, CAPs can be used to enter/eject cartridges for
LSM 0.
Elevators
Elevators are considered a type of pass-thru port. Each elevator has three logical pass-
thru connections per rail. Each rail can pass-thru to the other three rails.
