How to configure Standalone Tape Drive/Auto loader/Library with Symantec Backup Exec for Windows Servers
1. Make sure the device is detected in the Windows Device Manager as shown in the Figure 1 below.
2. Make sure SCSI ID 0,1, and 6 is not assigned as they are reserved SCSI IDs. To check, go to Device Manager as shown in Figure 2 below.
Following is the recommended configuration for SCSI settings.
SCSI ID recommendation for standalone tape drive, Auto loader/Library.
SCSI ID:0 and 1 is basically reserved for hard drives because they are fast devices and hence require lowest priority.
SCSI ID:6 The target ID 6 is reserved for automatic configuration of SCSI devices (through plug and play SCSI a.k.a. SCAM)
Tape devices, Auto loaders, and Libraries receive the next higher SCSI ID and so on. The reason for higher priority on the SCSI bus is because they are considerably slower devices. They require a much large time slice to accomplish tasks, whereas a hard disk requires a very small time slice because of how fast it is. Typically hard disks are set with the lower SCSI ID# such as 0 and 1.
Usually the SCSI IDs may be set on the back of the unit via dials or toggle switches. For more information about setting SCSI ID, please contact your drive manufacturer.
The following is an example of what a SCSI map of a Library configured with three SCSI tape devices may look like:
SCSI ID:2 - Robotic Arm (Also referred to as the Picker Arm/Changer Arm)
SCSI ID:3 - Tape Drive 0
SCSI ID:4 - Tape Drive 1
SCSI ID:5 - Tape Drive 2
NOTE: Backup Exec for Windows Servers, in general requires that the Auto loader/Library's Robotic Arm SCSI ID# precedes the SCSI ID# of the tape drive(s) and then configure the tape devices SCSI IDs in an ascending order as shown above.
3. Once the proper SCSI ID is assigned to the drive, Install the Symantec drivers with the help of the information in the Related Documents section of this TechNote
4. After the installation of Symantec drivers, go to the Devices tab and check the device presence, Figure 1 shows a Typical Standalone Tape drive and Figure 2 shows a Typical 6 slot Autoloader.
