IVM mkgencfg Command

Purpose

Performs the initial logical partition configuration for the managed system. This command is valid only in an Integrated Virtualization Manager environment.

Syntax

mkgencfg -o init [-i "ConfigurationData" ] [ -m ManagedSystem ]

Description

The mkgencfg command performs the initial logical partition configuration for the managed system. As part of the initial configuration, virtual Ethernet adapters are created in the management partition. The virtual Ethernet MAC address prefix can optionally be configured through this command.

Flags

-o Operation The type of operations:
init - Perform initial logical partition configuration actions for the managed system
-i ConfigurationData The configuration data consists of attribute name/value pairs, which are in comma separated value (CSV) format. The format of a configuration record is as follows: 
"attribute-name=value,attribute-name=value,..."
Note that certain attributes accept a comma separated list of values, as follows: 
""attribute-name=value,value,...",..."
When a list of values is specified, the attribute name/value pair must be enclosed in double quotes. Depending on the shell being used, nested double quote characters may need to be preceded by an escape character.

The valid attribute names for configuration data are:

  • mac_prefix - This must be specified as a 3 byte hexadecimal value. The first 2.5 bytes of the MAC address to be assiged to all virtual Ethernet adapters for this managed system. Additionally, the value must not be a multicast address (010000 bit must be off), and must be a private address (020000 bit must be on). An example MAC address prefix is 0642A0.
  • pend_configured_max_lpars - The maximum number of partitions supported by the management partition after the next restart
-m ManagedSystem The name of the managed system. This attribute is optional because there is only one system to manage. The name may either be the user-defined name for the managed system, or be in the form tttt-mmm*ssssssss, where tttt is the machine type, mmm is the model, and ssssssss is the serial number of the managed system.

Exit Status

This command has a return code of zero on success.

Security

This command is not accessible by users with the ViewOnly role.

Examples

  1. To initialize the logical partition configuration for the managed system using defaults, type: 
    mkgencfg -o init
  2. To initialize the logical partition configuration for the managed system with support for 17 partitions and a MAC prefix of 0x06ABC0, type: 
    mkgencfg -o init -i "pend_lpm_max_lpars=17,mac_prefix=06ABC0"
