HP-UX Release 11i provides you with several new HP-UX commands
for configuring and managing HP Superdome partitions and hardware, including: parcreate, parmodify, parremove, parstatus, parunlock, fruled, and frupower.
These commands allow you to create, modify, and monitor partitions,
get detailed system hardware information, and manipulate LEDs and
power.
When using these commands, you can specify cells and I/O chassis
using the methods shown in “Specifying Cells and I/O Chassis”.
Table 4-3 “HP-UX Commands for Configuring Superdome Partitions” describes the Superdome
configuration commands and lists the sections where you can find
each command's syntax and more details on its use.
Table 4-3 HP-UX Commands for Configuring Superdome Partitions
| Command | Description |
|---|
| parcreate | Create a new partition; root permission is required. See “parcreate Command”. |
| parmodify | Modify an existing partition; root permission is required. See . |
| parremove | Remove an existing partition; root permission is required. See “parremove Command”. |
| parstatus | Display partition information and hardware
details for a Superdome complex. See “parstatus Command”. |
parunlock | Unlock complex profile data (use this
command with caution); root permission is required. See “parunlock Command”. |
| fruled | Turn the amber service LEDs on or off
for cells, cabinets, and I/O chassis. See the fruled(1) manpage
for details. |
| frupower | Turn power on or off for cells and I/O
chassis; root permission is required. See the frupower(1M) manpage
for details. |
Advantages of Using the HP-UX Superdome Configuration
Commands |
 |
You can use several different tools to manage, configure,
and monitor the partitions and hardware within a Superdome complex,
as discussed in “Overview of Partition Management Tools”.
The HP-UX Superdome configuration commands have the following advantages
over the other tools:
They provide a simple, command-driven
interface you can use when HP-UX is in single-user mode, and when
X-Windows support is not available.
They support creating scripts to log and monitor
status information for all partitions and hardware in a Superdome
complex.
They do not require operating a graphical interface.
Specifying Cells and I/O Chassis |
|
When you use the HP-UX Superdome configuration commands to manage,
configure, and inquire about cells and I/O chassis, you must use the
cell and I/O chassis notation described in this section.
Cell Format
Use either of the following two formats to specify cells when
using the HP-UX Superdome configuration commands:
Global Cell
Number Format
This cell ID format is identical to the cells' HP-UX
hardware path, as reported by ioscan.
In global format, cells in cabinet 0 are numbered from 0 to
7, and on SD64000 servers cells in cabinet 1 are numbered from 8
to 15.
| Cell Slot | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Cabinet 0 Global Format | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
Cabinet 1 Global Format | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |
Cell Hardware Location Format
This cell ID format uses two numbers to represent each cell:
the cabinet ID and the cabinet-relative cell ID (the cell
slot where the cell resides).
In hardware location format, cells in cabinet 0 are numbered
from 0/0 to 0/7, and on SD64000 servers cells in cabinet 1 are numbered
from 1/0 to 1/7.
| Cell Slot | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Cabinet 0 HW Loc Format | 0/0 | 0/1 | 0/2 | 0/3 | 0/4 | 0/5 | 0/6 | 0/7 |
Cabinet 1 HW Loc Format | 1/0 | 1/1 | 1/2 | 1/3 | 1/4 | 1/5 | 1/6 | 1/7 |
Both of these cell ID formats specify each cell's
precise physical location in a Superdome complex. For example parstatus -c9 and parstatus -c1/1 refer to the same cell.
I/O Format
Use the following I/O hardware location format when
specifying an I/O chassis to the HP-UX Superdome configuration commands:
The cabinet, bay,
and chassis fields (for example, 0/1/3) specify the physical location of the I/O chassis. The
values of these fields are as follows:
cabinet is either
0 (the left cabinet) or 1 (the right cabinet, if present).
For the first release, up to two Superdome cabinets are supported. Superdome
64 Way systems have two cabinets, all others have one.
bay is either 0 (the
front bay in cabinet) or 1 (the rear bay).
chassis can be from 0 to 3.
HP Superdome server support two 12-slot I/O chassis per I/O
bay for the first release. Each bay can contain chassis 1 (the left
chassis in the bay) and chassis 3 (the right chassis).
The following example 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).
You also can use the parstatus -I command to list all I/O chassis within a Superdome
complex, and can use the rad -q command to list of all PCI I/O slots currently
available in the local partition and their status. These commands' output
show which chassis are present.
In this example, both commands show details for chassis 0/0/1
and 0/1/3.
