Tivoli Storage Manager for Windows: Administrator's Guide


Troubleshooting Device Configuration

The following sections describe procedures for troubleshooting device configuration. The sections give pointers to additional information where applicable.

Displaying Device Information

You can display information about devices connected to the TSM server by using the Device Information utility.

  1. From the TSM Console, expand the tree to the machine you are configuring.
  2. Expand TSM Device Driver and Reports.
  3. Click Device Information. 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.

Displaying the Event Log to Find Device Errors

You can display the Windows Event Log to understand the problem behind some device errors.

  1. In the TSM Console, select Launch. From the Administrative Tools window, open Event Viewer. Information on system events is displayed.
  2. Under the column labeled Source, look for events that are labeled with "AdsmScsi".

    You 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.

  3. 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.

Setting the Library Mode

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:

See the documentation for the device to determine how to set it for the appropriate TSM mode.
