After you have successfully installed the PPU 8.x software, you need to configure the PPU software connection to the utility meter. The utility meter must be configured on every partition in the complex (including virtual partitions on HP-UX systems).

NOTE: The following configuration procedure assumes your utility meter has been installed on the PPU system’s network by your HP service representative. If the utility meter is not installed, contact your HP service representative.

You may need to perform up to three steps to configure a partition. At a minimum, you must set the name of the utility meter. If you want to specify a name other than your partition’s hostname as the system identifier, you must perform additional steps. If you want to set a cap, or maximum, for the number of active cores (HP-UX and OpenVMS systems only), you must also perform additional steps.

To summarize, in order to configure the PPU software you must do the following:

  1. Configure the utility meter (required)

  2. Configure the system identifier of the partition (optional)

  3. Configure the cap limiting the number of active cores on the partition (optional; HP-UX and OpenVMS only)

Configuring the Utility Meter (Required)

For HP-UX

To configure the utility meter, execute the following command on each partition:

/usr/sbin/ppuconfig -m meter

Where meter is the fully-qualified hostname or IP address of the utility meter. This command/option performs a communication test to the utility meter and starts the ppud daemon.

For Windows Server 2003

To configure the utility meter, open a command window on each Windows partition on the server and execute the following command:

C:\Program Files (x86)\Hewlett-Packard\ppu>
     ppuconfig -m meter

Where meter is the fully-qualified hostname or IP address of the utility meter. This command/option performs a communication test to the utility meter and starts the PPU Service. The command assumes that PPU was installed in the default location.

IMPORTANT: The PPU 8.x software is inoperable if the Utility Meter software is not version 7.3 (or higher).

For OpenVMS

To configure the utility meter, execute the following DCL command on each partition:

$ ppu config/meter_address=meter

Where meter is the fully-qualified hostname or IP address of the utility meter. After the utility meter is defined, you must start the PPU_SERVER process. Use the DCL command below to start the server:

$ ! note the location of PPU$ROOT is not required to be
$ ! SYS$SPECIFIC but it must be consistent with the
$ ! definition in SYSTARTUP_VMS.COM
$ !
$ DEFINE/SYS/EXEC/TRANS=CONCEAL PPU$ROOT ’F$TRNLNM("SYS$SPECIFIC")
$ @SYS$STARTUP:PPU$STARTUP
%RUN-S-PROC_ID, identification of created process is 00000438
8 cores are now active

Configuring the System Identifier (Optional)

For HP-UX

The system identifier of a partition enables you to track your PPU system. The default system-identifier is the hostname of your partition. If you want to protect the identity of the hostname for your partition, you can change the system identifier to any value you choose. Examples of a system identifier are: an asset number, an HP support tag, or a description of a physical location.

To set the system identifier of the partition, execute the following command:

/usr/sbin/ppuconfig -s system_id

Where system_id is an identifier for your partition.

NOTE: You can set the utility meter and system identifier with the single command: /usr/sbin/ppuconfig -m meter -s system_id

For Windows Server 2003

The system identifier of a partition enables you to track your PPU system. The default system-identifier is the hostname of your partition. If you want to protect the identity of the hostname for your partition, you can change the system identifier to any value you choose. Examples of a system identifier are: an asset number, an HP support tag, or a description of a physical location.

To set the system identifier of the partition, execute the following command:

C:\Program Files (x86)\Hewlett-Packard\ppu>
     ppuconfig -s system_id

Where system_id is an identifier for your partition.

NOTE: You can also set the utility meter and system identifier with a single command:
C:\Program Files (x86)\Hewlett-Packard\ppu>
     ppuconfig -m meter -s system_id

For OpenVMS

The system identifier of a partition enables you to track your PPU system. The default system identifier is the hostname of your partition. If you want to protect the identity of the hostname for your partition, you can change the system identifier to any value you choose. Examples of a system identifier are: an asset number, an HP support tag, or a description of a physical location.

To set the system identifier of the partition, execute the following DCL command:

$ ppu config/system_id=system_id

Where system_id is an identifier for your partition.

NOTE: You can set the utility meter and the system identifier with the single command:
$ ppu config/system_id=system_id/meter_address=meter

Limiting the Number of Active Cores (Optional; HP-UX and OpenVMS)

You can specify the number of active cores on each partition in your PPU system. To cap the number of active cores for a given partition, execute the following command:

HP-UX: /usr/sbin/ppuconfig -rc number

OpenVMS: $ PPU CONFIG/CAP=number[/RECONCILE]

Where number is the maximum number of active cores you want in the partition.

The -r option on the HP-UX command and the /RECONCILE qualifier on the OpenVMS command causes the cap to take effect immediately (limiting the number of active cores without waiting for a reboot).

NOTE: You cannot limit the number of active cores with the -c option in a virtual partition environment (vpar).

See “ppuconfig (1M) Manpage” for details on specifying a cap limiting the number of active cores.

Viewing the System Settings (HP-UX, Windows and OpenVMS)

You can use the ppuconfig command (with no options) to view the settings for the utility meter and system identifier, and if a cap limiting the number of active cores is set.

Example 3-1 Viewing system settings using the ppuconfig command

Use the following commands to verify general system settings:

HP-UX:
/usr/sbin/ppuconfig

OpenVMS:
$ PPU CONFIG

Windows Server 2003:
C:\Program Files (x86)\Hewlett-Packard\ppu> ppuconfig

You should see output similar to:

Utility Meter IP/Hostname:                   meter1.corp.com
System Identifier:                           superdome1
Cores to be active at next reboot (cap):       all
Cores that can be activated without reboot:    0
Active Cores:                                  4

See the “ppuconfig” descriptions in the appropriate system-specific Appendix (B or C) for details of the ppuconfig command.
