The following sections present choices and procedures you need to be aware of when configuring devices for TSM. The sections give pointers to additional information where applicable.
You cannot share tape drives defined to TSM with other applications. Errors and operation failures can occur when other applications attempt to use devices defined to TSM. If you want to temporarily use a drive with another application, you can delete the drive definition from TSM and lower the mount limit for the corresponding device class. Define the drive to TSM again when the drive is available for TSM use.
Also, you cannot use a device for labeling volumes with the TSM DSMLABEL command at the same time that the server uses the device for other processes. For example, if the server is using a device to back up client data, you cannot use that device for labeling volumes.
If you have not already done so, register the license for the device support module that you purchased. For more information on licensing, see Tivoli Storage Manager Licensing.
For TSM to access a SCSI library, 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:
Refer to the documentation for your device to determine how to set it to a mode appropriate for TSM.
