  2. Some physical location codes begin at zero and count upwards, others begin at one and count upwards. The storage facility uses parts from different hardware platforms. Most Licensed Internal Code and firmware logical resources identifiers begin at zero and count upwards.
  3. Some PCIe and PCN cards do not include ports C7-T3, C7-T4, or C7-T10.

  1. Microbay locations are reported as a subassembly of the I/O enclosure PCIe and PCN card. Each microbay is located behind a predefined storage enclosure location. For example, R1-M04 is located behind R1-G04. See Storage enclosure location codes (Models 98x, FC/SAS, 12 and 24 drive slots). The associated HPFE Gen2 enclosure pair can be located in a different rack than the microbay pair, or in a different location in the same rack.
