On your controller node, run detect -h
from a Command Prompt window or terminal window. This displays file names and other information about all SCSI devices accessible by the controller node.
Note. The detect utility is found in the bin\JB subfolder under the main DPX installation folder.
The following is sample output from detect -h:
Note that the output is divided into three distinct parts. The horizontal lines between parts does not appear on your display. The three parts are:
Part 1 – SCSI device scan as presented by the operating system
Part 2 – DPX device identification with associated Unique ID
Part 3 – Tape library information gathered from reading the media changer device
From Part 1 of the detect -h output, identify the media changer device file and the tape drives. The following table lists common Device ID nomenclature:
Operating System | Media Changer ID | First Storage Device ID |
---|---|---|
Windows | \.\sync_sa0 or \.\Changer0 | \.\Tape0 |
Linux | /dev/sg0 | /dev/nst0 or /dev/st0 |
Note the Media Changer ID. This information is needed later when the library is added to the Enterprise.
Populate the worksheet below to note critical information about each tape drive. This information is needed later when the tape devices are added to the Enterprise.
Device Number | Serial Number | Unique ID | Device Name | |
Source: | from Part 3 of detect -h | from Part 3 of detect -h | from Part 2 of detect -h | user defined |
Notes: | This is the numeric digit that appears after "TAPE_DRIVE" | The end of the Unique ID MUST correspond to the Serial Number in column 2 of this table | This is a logical name for referring to the device, up to 14 characters, no spaces | |
Example: | 0 | 4322103504 | ULT3580-TD1 4322103504 | DPX00 |
