determining the SCSI id

Before you configure your system to support your new HP Surestore DLT1 drive, you need to determine what SCSI ID to use. The SCSI ID 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 00-00-0S-0 1.0 GB 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 your new tape drive.

configuring the device files

To install the HP Surestore DLT1 drive on an IBM workstation running AIX, 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:

1If 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

2If 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.

3Select from the window: "change/show characteristics of a tape drive"

4From the pop-up window, select "ost" or "Other SCSI tape drive" as the tape drive you wish to change. Do not choose "4mm2gb".

5Change the block size field to 0, and click on the "DO" button or press [Enter] to apply the change.

HP DLT1 drives will work with tar, cpio, backup, restore and dd. For systems other than the 43P, the drive is also boot-capable, provided a boot tape is generated using mkszfile and mksysb.

Once the device files have been created, you should confirm that your new tape drive is working properly. See Verifying Installation.

device file names under AIX

Use device filenames as listed below for the combination of Rewind on Close, Retension on Open, and Compression that you want:

Filename Rewind on CloseRetension on OpenCompression

/dev/rmtn

No

/dev/rmtn.1

No

/dev/rmtn.2

/dev/rmtn.5

/dev/rmtn.6

The n in the filename is the instance number assigned to the drive by the operating system, where 0 is the first device, 1 is the second and so on.

Rewind on Close Normally, the drive repositions the tape to BOT (Beginning of Tape) when the device file is closed. Using the no rewind option is useful when creating and reading tapes that contain multiple files.

Retension on Open Retensioning consists of winding to EOT (End of Tape) and then rewinding to BOT, in order to reduce errors. If this option is selected, the tape is positioned at BOT as part of the open process. DLT1 drives do not require retensioning, so you should not use device fields that send retensioning commands.

Compression Compression can be disabled or enabled.
