Using the IMFEXEC HMC statement

This section describes the requirements for using the IMFXEC HMC commands and their command syntax.

Overview for using the IMFEXEC HMC command

IMFEXEC HMC is a command for advanced users that allows you to issue commands to IBM System z Support Elements from BMC AMI Ops Automation EXECs.

By default, this feature is disabled when BMC AMI OpsA is installed.

Warning

The IMFEXEC HMC command can alter your IBM machine, which might result in outages or incur unexpected financial costs. For example, issuing the IMFEXEC HMC command can result in increasing the machine capacity.

BMC recommends that only users who have proficiency in operating the System z Support Elements and Hardware Management Console (HMC) should use the IMFEXEC HMC command. You should also already be familiar with HMC and System z terminology and properties.

In addition, the user control and confirmation features available on the actual HMC do not apply when using the IMFEXEC HMC command in an EXEC issued from BMC AMI OpsA. For example you can configure the HMC to require a user to enter a password prior to performing an IPL (issuing a Load command) of the system. With the IMFEXEC HMC command, the Load command executes without requiring any confirmation.

You can use the IMFEXEC HMC command the way you would use the HMC to perform operations against multiple Support Elements or multiple Central Processor Complexes (CPCs) or System z machines.

For example, you can use the IMFEXEC HMC command to perform the following tasks:

  • Obtain the System z topology of the current interconnected Central Processor Complexes (CPCs) as well as the images, capacity records and activation profiles on a particular CPC
  • Query various CPC, image (LPAR), capacity record, and activation profile information
  • Set various configuration values related to CPC, image, and activation profiles
  • Issue commands against both the CPC and image (LPAR) to perform minor or even significant hardware- and software-related functions
