Locking and Unlocking the I/E Stations

Scalar i500 User's Guide
Each control module and expansion module has an I/E station door with
multiple open and close sensors. A secondary door located behind the
I/E station door acts as a redundant indicator as to whether the I/E
station is opened or closed. When you are finished accessing the I/E
station, make sure the station door is fully closed.
Administrators can use this operation to lock or unlock the doors for all
I/E stations that are configured as I/E station slots. If all I/E station slots
are configured as storage, this operation unlocks the control module I/E
station only.
Note: Some host applications use a command to lock and unlock I/E
station doors. This command usually cannot be overridden by
the library. Use the host application to lock or unlock I/E
station doors if this occurs. Using the library lock/unlock
operation may affect the host application. See your host
application documentation for information.
There are three reasons the I/E station door locks:
• The library imports or exports a cartridge from the I/E station door.
While the library is attempting to import or export a tape from a
given I/E station slot, only the associated I/E station door is locked
in the closed position. All other I/E station doors remain accessible.
On a "get" from an I/E station slot, the associated I/E station door
remains locked until the media has been successfully moved to its
destination. This allows the media to be returned to the I/E station
slot in the event of a put error.
• A user has requested that the I/E station door be locked.
• If the I/E station slots are configured as storage slots, the door is
always locked. When all I/E station slots are configured as storage
slots, you can use the Locking and Unlocking I/E station operation to
unlock the I/E station in the control module. When the I/E station is
unlocked, you can open the main access door on the control module.
This, in turn, unlocks all remaining I/E stations in the library,
allowing you to access all remaining access doors in the library.
