Table 27. Problem Determination Using Search Database for Volumes Window (continued)
Problem Scenario Action
Locating other Inaccessible Volumes
Search the database to determine if the 3494 Tape Library
contains any other inaccessible volumes.
1. Leave the Volser: field blank, select the Yes radio
button for the Inaccessible Volser Flag, then select
the Search push button. The database records, if any,
for the inaccessible cartridges are shown.
2. Perform the “Specific Inaccessible Volume” procedure
(see Table 27 on page 457).
Locating Misplaced Volumes in other Libraries
If an operation on one library failed because the volume
was misplaced and you cannot find the volume in that
library, check the inventories of the other 3494 Tape
Libraries to see if it was put in another library by
mistake.
1. At each library in the installation, enter the volser of
the misplaced volume in the
Volser:
field, then select
the Search push button.
2. If a database record is found for the volser, eject it
from that 3494 Tape Library and place it in the
convenience I/O station of the 3494 Tape Library
with the original error.
Problem Determination Using Whole Queue
When trying to determine why a particular library operation is not completing as
expected, you can use the Whole Queue window (see Figure 111 on page 190) to
determine what, if anything, needs to be done. This is useful particularly in the
absence of any host console messages. Select the Whole queue... option on the
Queues menu. Each 3494 Tape Library operation in the queue has status that is one
of the following:
Queued
The operation has not yet started. Other operations are in the queue that
have a higher priority or were placed in the queue first. If you do not want
to wait for the operation to progress through the queue, select the
Promote
a command in the queue
option on the Commands menu and promote the
operation.
In-Progress
The operation is being performed. No operator action is needed.
Blocked
The operation is waiting for another operation to complete before it can be
started. When the blocking operation completes, the status of the operation
changes to in-progress. No operator action is needed.
Intervention-Required Conditions and Actions
When the Library Manager determines that an error or exception condition that
requires your assistance to correct has occurred within the 3494 Tape Library, it
performs the following actions:
1.
Adds the detected condition to the list of outstanding operator
intervention-required conditions that the Library Manager maintains.
2. If not previously in the Intervention-Required state, places the 3494 Tape
Library in that state and notifies all attached hosts of the state change. The
System Summary window is updated to indicate intervention is required.
The notification that the 3494 Tape Library is in the Intervention-Required state
generates the following console message for 3494 Tape Libraries managed
under DFSMS/MVS System-Managed Tape environment: CBR3762E Library
library-name intervention required .
