Extended Vital Product Data
Previous  Top  Next

Vital product data (VPD) pages are applicable to all SCSI family devices. They are returned by SCSI Inquiry commands and are used to return vendor-specific information about the selected device. The vital product data may include vendor identification, product identification, unit serial numbers, device operating definitions, manufacturing data, field replaceable unit information, and other vendor specific information. The SCSI standard defines the structure of the vital product data, but not the contents.

If you are trying to obtain device serial numbers, or are using fibre channel disks in a SAN, then the VPD pages can provide extremely useful information including world-wide-names and target port numbers.

As VPD information is vendor-specific, we only provide information in hexadecimal format. You should contact your SCSI vendor to obtain record layout for the VPD pages.

The SCSI-3 specification now requires all devices to contain VPD pages, but older devices that are not SCSI-3 compliant have no such requirement. If the selected devices has no VPD information, then the window shown below will simply not appear. If the selected device does have VPD, but it does not display when you select it, then the feature is disabled. In order to enable reporting VPD information, just select the
Display Extended Vital Product Data option from the Alerts menu on the main window. Once that feature is checked then the program will poll and report this information. A program restart is not required.

This window will automatically close once the parent device window closes.
