SCSI Element Addressing

Element addressing is used by SCSI hosts to identify library components.

Note:

Changing the library configuration or partition configuration can cause the library to re-assign element IDs.

The SCSI element address depends on the element type. Each library or partition uses a fixed starting address for each element type. Then, within each element type, the element addresses are sequential.

  • Storage Elements (storage cells)
    • Begins at 2000 in left-most module.
    • Numbered top to bottom, back to front, and left to right.
  • Import/Export Elements (CAPs)
    • Begins at 10 for the left-most rotational CAP in the library.
    • All rotational CAPs are numbered first (top to bottom and left to right), followed by the left Access Module CAP and then the right Access Module CAP (numbered top to bottom, back to front, and left to right).
  • Data Transfer Elements (drives and empty drive bays)
    • Begins at 1000 in the left-most Drive Module or Base and increments by one for every drive or empty drive bay.
    • Numbered top to bottom, left to right.
