Determining the SCSI ID

Before you configure your system to support your Ultrium drive, you need to determine which SCSI ID to use. IDs must be unique for each device attached to the SCSI bus. To list the existing devices, use the following command:

% lsdev -C grep SCSI

This will produce output that looks similar to:

scsi0 Available 00-00-0S Standard SCSI I/O Controller hdisk0 Available 10-60-00-0,0 16 Bit LVD SCSI Disk Drive

rmt1 Defined 00-00-0S-2,0 Other SCSI Tape Drive

The SCSI ID is in the series 00-00-0S-X,0, where X is the SCSI ID. Review the list of existing SCSI IDs and choose an available ID to assign to the new tape drive.

Configuring the Device Files

To install an HP Ultrium drive on an IBM workstation you will need to create the appropriate device files for the drive.

NOTE: Do not choose the smit option of “4mm2gb” as the Tape Device Type. This is reserved for Connor drives. If you use it with HP drives, you will get the error “Device to be

configured does not match the physical device at the specified connection location”.

To change to variable block mode, use the following procedure:

1.If you are using a graphics terminal running X-Windows, then at a Windows terminal, type:

smit tape

If you are using a non-graphics terminal, at the command line type:

% smit -C tape

2.If no device has been configured at this address before, select “add a tape drive” to set up the address. From the pop-up window, select “ost” or “Other SCSI tape drive” as the tape drive you wish to change and choose connection addresses as appropriate.
