PAUSE key
This topic describes the PAUSE touch key on the library's Activity screen.
The TS3500 Tape Library features a PAUSE touch key that you should press before you
power off the library or open the front door. Located on the Activity screen on the display,
the PAUSE key causes the cartridge accessor to park itself (to quickly resume operation
later) and give you clear access to the library's interior should you need to open the front
door.
If you press the PAUSE key by mistake, wait until the end of the 30-second timeout. The
library will automatically resume the operation.
Attention: After you open the front door, the library rejects requests for new operations
until you close the door and the inventory is completed. IBM® recommends that you halt
the application (for example, Tivoli® (R) Storage Manager, Legato, or Veritas) prior to
pressing the PAUSE Key. Process failures may occur if you do not halt the application before
you open the front door.
