IBM TotalStorage 3494 Tape Library, Руководство оператора

Страница: 106 / 605

Operator assistance is required if an error or exception condition occurs from
which the 3494 Tape Library cannot recover on its own. Depending on the type of
error or exception condition experienced, some or all of the 3494 Tape 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. You 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 you can
correct the error, the 3494 Tape Library may be placed in Pause mode, and the
front doors may be opened to provide operator access. After you resolve the
problem, you may return the 3494 Tape Library to Auto mode.
If you cannot resolve the problem, you may start Manual mode operations in the
3494 Tape Library. When in Manual mode, the Library Manager instructs you to
perform manual mount and demount operations until a service representative
resolves the problem. After the problem is resolved, you can return the 3494 Tape
Library to Auto mode.
Note: When the 3494 HA1 Option is installed, control switches over automatically
to the hot standby component, and the failed component is 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 3494 Tape Library do not require any system
administrator involvement. System administrator involvement may be required if
an error condition occurs that you cannot resolve. 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 3494 Tape Library that have
problems with their external labels or 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
intentionally damaging the Library Manager database or other operations.
Use of password protection is optional.
Error Detection and Reporting
When the 3494 Tape Library is powered on, the Library Manager, the tape
subsystems, and the VTSs perform power-on diagnostic tests. The 3494 Tape
Library performs real-time error detection, fault isolation, error reporting, and error
recovery during normal operation.
In the event of a failure, the information is reported to the attached hosts for
logging and possible host recovery actions. When appropriate, the 3494 Tape
Library drive support software posts host console messages in the control program
to request operator-required actions or to present information for the operator. See
Chapter 7, “Remote Library Manager Console Feature,” on page 417.
