IBM Tape Library Magstar 3494, Operator'S Manual

Page: 68 / 378

The remote power control, a 3494 feature for AS/400, supports both local and
remote power controls. When the library is in local power mode, an operator can
activate the power-on and the power-off sequences.
When in remote power mode, each host, through its AS/400 interface, can request
that the power-on or power-off sequence be initiated. Any host requesting a
power-on sequence will cause the 3494 to power on unless the library is already
powered on. Only the last host requesting the library to power off will initiate a
power off-sequence.
Operator Involvement
During normal automated operation, no operator attendance is required except to
add or to remove cartridges.
Operator assistance is required if an error or exception condition occurs from which
the library cannot recover on its own. Depending on the type of error or exception
condition experienced, some or all of the library operations are suspended until the
problem is corrected. If an error occurs that prevents the movement of cartridges,
the library manager suspends performing requests that require cartridge accessor
movement. The operator can use the library manager or the remote library manager
console (if the optional Remote Library Manager Console feature is installed) to
identify the cause of the error. If the operator can correct the error, the library may
be placed in Pause mode, and the front doors may be opened to provide operator
access. After the problem is resolved, the library may be returned to Auto mode.
If the problem cannot be resolved by the operator, the operator may start Manual
mode operations in the library. When in Manual mode, the library manager instructs
the operator to perform manual mount and demount operations until the problem is
resolved by a service representative. After the problem is resolved, the operator can
return the library to Auto mode.
Note: When the high availability model is installed, control will automatically switch
to the ‘hot standby’ component and the failed component will be marked
unavailable. Concurrent maintenance can be performed to repair the failing
unit. Operator involvement is needed only when a second failure occurs
before the first failure is repaired.
System Administrator Involvement
Normal daily operations of the library do not require any system administrator
involvement. System administrator involvement may be required if an error condition
occurs that cannot be resolved by the operator. A system administrator can obtain
operational and performance information from the library manager or the remote
library manager console (if the optional Remote Library Manager Console feature is
installed) at any time.
The system administrator may also use the library manager or remote library
manager console to search for cartridges in the library that have problems with their
external labels, cartridges that have been misplaced or have other problems that
need to be corrected.
Note: The tasks performed by a system administrator are typically
password-protected to prevent unauthorized personnel from inadvertently or
