Product Revision Level
Example
If new drive families or variants support features that are not available in previous generation
products, you can detect the existence of these features through the SCSI
MODE SENSE and LOG
SENSE
commands. Exact details will become available as new products are defined. There is no
need to limit driver or application connectivity to a single HP Ultrium product type.
To determine the drive technology family:
Examine only the first eight bytes of the Product ID field (the text “Ultrium ”).
To determine the Ultrium format generation:
Use one of the following two methods, of which the second is preferred:
• Examine the character in byte 9. A “4” indicates format LTO 4 (1600 GB capacity at 2:1
compression) and so on.
• Preferred method: Use the SCSI REPORT DENSITY SUPPORT command.
For an LTO 4 product with LTO Ultrium 4 media, the following will be returned:
“Ultrium ” This will be the same for all HP Ultrium products, regardless of generation or model.
1st byte: Generation identifier:
“4” LTO 4 (1600 GB at 2:1 compression)
2nd byte “–” Hyphen separator (ASCII 2Dh)
3rd–6th bytes “SCSI” SCSI protocol, regardless of transport or interface type
1st byte Product codename ID:
“A”
“B”
“H”
