Using the SE or HMC to configure a PCI function for a partition

You can use the IBM Z® or LinuxONE Support Element (SE) or an attached Hardware Management Console (HMC) to control the configuration state of PCI functions in an LPAR or DPM partition.

Before you begin

You can control the configuration state of PCI functions in a partition from a Linux® instance that runs in the partition in LPAR or DPM partition mode, see Controlling the online state in Linux.

The steps that follow are primarily intended to configure a PCI function for a partition, as a prerequisite for a Linux installation (see Using a PCI function during a Linux installation). The steps are based on an SE interface but after selecting the hardware system, are similar on an HMC.

Procedure

  1. If you work from an HMC, select your hardware system and select Recovery > Single Object Operations.
  2. Select your partition and open the FIDs tab.

    As shown in Figure 1, PCI functions are identified through FIDs. The value in the Type column confirms that an FID corresponds to a network adapter PCI function.

    Tip: You can select multiple FIDs to proceed with configuring multiple PCI functions for the partition.
  3. Select your FID, then click Tasks > CHPID Operations > Configure On/Off to open the Configure On/Off tab.

  4. Select the FID or FIDs that you want to configure, then click --- Select Action --- > Toggle.
    The state in the Desired State column changes from Standby to Online.
  5. Click OK.
    The state in the Current State column changes from Standby to Online.

    This operation fails if the PCI function is already online in another partition.
