Use the cell and I/O chassis notation described in this section when you manage, configure, and inquire about cells and I/O chassis using the nPartition configuration commands.

Details are in the “Cell Specification Formats” and “I/O Specification Format” sections that follow.

Cell Specification Formats

Use either of the following two formats to specify cells when using the nPartition configuration commands: “Global Cell Number Format” or “Cell Hardware Location Format”.

  • Global Cell Number Format. The global cell number format is identical to the cells' HP-UX hardware path, as reported by the HP-UX ioscan command. In global format, each cell is given a single unique number that indicates the relative location of the cell in the entire server complex.

    Table A-1 Cell IDs in Global Cell Number Format

    Cell Slot01234567

    Global Format for rp7405/rp7410, rp7420, rp7440, rx7620, and rx7640

    01

    Global Format for rp8400, rp8420, rp8440, rx8620, and rx8640

    0123
    Superdome Cabinet 0 Global Format01234567

    Superdome Cabinet 1 Global Format

    89101112131415

     

  • Cell Hardware Location Format. In cell hardware location format, each cell is identified using two numbers that specify the cabinet and the cell slot with the cabinet where the cell resides: cabinet/slot.

    Table A-2 Cell IDs in Hardware Location Format

    Cell Slot01234567

    Hardware Location Format for rp7405/rp7410, rp7420, rp7440, rx7620, and rx7640

    0/00/1

    Hardware Location Format for rp8400, rp8420, rp8440, rx8620, and rx8640

    0/00/10/20/3

    Superdome Cabinet 0 Hardware Location Format

    0/00/10/20/30/40/50/60/7

    Superdome Cabinet 1 Hardware Location Format

    1/01/11/21/31/41/51/61/7

     

Both cell ID formats specify the location of a cell in a complex. For example, parstatus -c9 and parstatus -c1/1 specify the same cell.

# parstatus -c9 [Cell] CPU Memory Use OK/ (GB) Core On Hardware Actual Deconf/ OK/ Cell Next Par Location Usage Max Deconf Connected To Capable Boot Num ========== ============ ======= ========= =================== ======= ==== === cab1,cell1 active base 4/0/4 8.2/ 0.0 - no yes 1 # parstatus -c1/1 [Cell] CPU Memory Use OK/ (GB) Core On Hardware Actual Deconf/ OK/ Cell Next Par Location Usage Max Deconf Connected To Capable Boot Num ========== ============ ======= ========= =================== ======= ==== === cab1,cell1 active base 4/0/4 8.2/ 0.0 - no yes 1 #

I/O Specification Format

Use the following I/O hardware location format when specifying an I/O chassis to the nPartition configuration commands:

cabinet/bay/chassis

The cabinet, bay, and chassis fields specify the physical location of the I/O chassis. The values of these fields are as follows.

  • cabinet

    specifies the cabinet number where the I/O chassis resides.

    On HP rp7405/rp7410, rp7420, rp7440, rx7620, rx7640, rp8400, rp8420, rp8440, rx8620, and rx8640 servers, the server cabinet number always is 0.

    In HP rp8400, rp8420, rp8440, rx8620, and rx8640 complexes the I/O Expansion cabinet, if present, is 8.

    On HP Superdome servers, the cabinet number can be:

    • 0 — the left Compute cabinet.

    • 1 — the right Compute cabinet, if present.

    • 8 — an I/O Expansion cabinet, if present.

    • 9 — an I/O Expansion cabinet, if present.

  • bay

    specifies the I/O bay (within a cabinet) where the I/O chassis resides.

    On HP rp7405/rp7410, rp7420, rp7440, rx7620, rx7640, rp8400, rp8420, rp8440, rx8620, and rx8640 servers, the bay number always is 0.

    On HP Superdome servers, the bay number can be:

    • 0 — the front bay of a Compute cabinet, or the bottom bay of an I/O Expansion cabinet.

    • 1 — the rear bay of a Compute cabinet, or the middle bay of an I/O Expansion cabinet.

    • 2 — the top bay in an I/O Expansion cabinet.

  • chassis

    specifies the I/O chassis (within a bay).

    On HP rp7405/rp7410, rp7420, rx7620, rp8400, rp8420, and rx8620 servers, the chassis number is:

    • 0 — Chassis 0, which connects to cell 0 and is the left chassis as viewed from the cabinet rear: the left eight PCI card slots.

    • 1 — Chassis 1, which connects to cell 1 and is the right chassis as viewed from the cabinet rear: the right eight PCI card slots.

    On HP Superdome servers, the chassis number is:

    • 1 — Chassis 1, the left chassis in the bay, as viewed when facing the bay/chassis.

    • 3 — Chassis 3, the right chassis in the bay, as viewed when facing the bay/chassis.

    In HP Superdome servers all chassis are 12-slot I/O chassis, both in Compute cabinets and in I/O Expansion cabinets.

The example below shows the parstatus command listing details about two different I/O chassis (cabinet 0/bay 0/chassis 1, and cabinet 0/bay 1/chassis 3).

# parstatus -i0/0/1 [Chassis] Core Connected Par Hardware Location Usage IO To Num =================== ============ ==== ========== === cab0,bay0,chassis1 absent - - - # parstatus -i0/1/3 [Chassis] Core Connected Par Hardware Location Usage IO To Num =================== ============ ==== ========== === cab0,bay1,chassis3 active yes cab0,cell0 0 #

Use the parstatus -I command to list all I/O chassis within a server complex, regardless of the chassis cell connections and nPartition assignments.

Use the HP-UX rad -q command or olrad -q command to list the currently available PCI I/O slots in the local nPartition and their status. The rad command is available with HP-UX B.11.11, and olrad is available with HP-UX B.11.23 and HP-UX B.11.31.

In Example A-1, both the parstatus and rad commands show details for various chassis and slots, including chassis 0/1/3.

The parstatus -I command reports cabinet 0, bay 1, chassis 3 as cab0,bay1,chassis3.

2

The rad -q command and olrad -q command report cabinet 0, bay 1, chassis 3 as 0-1-3.
