Chapter 6: Performing Library Operations
Unlocking and Opening the I/E Station
Quantum Scalar i40 and Scalar i80 User’s Guide 145
Note that this does not completely remove library power (you need
to disconnect the power cords to do that).
• Disconnect the power cord from each power supply on the back of
the library. It may take 1 to 2 seconds for motion to completely
stop.
Caution: These methods are not recommended except in case of
emergency where it is vital that library operations be
stopped immediately. If you do not first perform a
shutdown as described in the sections above, the following
could occur:
– The library may not complete closing all data and log
files.
– If you turn off power or unplug the power cord while
writing to tape, the data on the tape could become
corrupted.
– If you unplug the power cord, the robot may become
frozen in the middle of an operation and unable to move
once library power is restored, possibly requiring a
service call.
Taking the Library
Offline
Some maintenance activities require that the entire library be taken
offline. To take the library offline, change the mode of all partitions from
online to offline. See
Taking a Partition Online or Offline on page 59 for
instructions.
Unlocking and Opening the I/E Station
The I/E station is locked during normal library operation. To access the
I/E station you must first unlock it. When you give the command to
unlock the I/E station, the robot physically moves to the unlock
mechanism and unlocks it. This takes a few seconds. Once unlocked,
you have 30 seconds to open the I/E station before it locks again.
