Tivoli Storage Manager for Windows Administrator's Guide
The following sections describe procedures for
troubleshooting device configuration. The sections give pointers to
additional information where applicable.
Administrators can display information about devices connected to the TSM
server by using the Device Information utility.
- Double click the
TSM Server Utilities icon on the desktop. The TSM
Server Utilities window opens.
- Click
Device Information in the Server Utilities tree in the left
panel. This utility provides a convenient way to find information about
devices available and defined to TSM.
The information provided by this utility is from the Windows
registry. Some of the information is put into the registry by the TSM
device driver. To receive accurate information, ensure that the device
driver is running. If the device driver is not running, the information
may be incorrect if device attachments have changed since the last time the
device driver was running.
Administrators can display the Windows Event Log to
understand the problem behind some device errors.
- In the
TSM Server Utilities, select Launch. From the
Administrative Tools window, open Event Viewer. Information
on system events is displayed.
- Under the column labeled Source, look for events that are
labeled with "AdsmScsi".
Administrators can also use filtering to see just the events related to
TSM. From the View menu, select Filter Events..., and
set the filter to show events with event ID 11.
- Double-click on the event to get information about the date and time of
the error, and detailed information. To interpret the data bytes that
are shown in the Data field, use the appendix in Tivoli
Storage Manager Messages that discusses device I/O errors.
For TSM to access a SCSI library device, the device must be set for the
appropriate mode. The mode that TSM requires is usually called
random mode, however, terminology may vary from one device to
another. Two examples follow:
- Some library devices have front panel menus and displays that can be used
for explicit operator requests. However, if the device is set to
respond to such requests, it typically will not respond to requests made by
TSM.
- Some library devices can be placed in sequential mode, in which
volumes are automatically mounted in drives by using a sequential
approach. This mode conflicts with how TSM accesses the device.
See the documentation for the device to determine how to set it for the
appropriate TSM mode.
