Enabling and disabling SR-IOV logical ports

You can enable or disable single root I/O virtualization (SR-IOV) logical ports by using the Hardware Management Console (HMC). The HMC must be at Version 9.1.0, or later.

Before you begin

You must be a super administrator to complete this task.

About this task

  • To disable an SR-IOV logical port, type the following command from the HMC command line:
    chhwres -m <managed-system> -r sriov --rsubtype logport -o d [-p <partition-name> | --id <partition-ID>] 
-a “adapter_id=<adapter-id>,logical_port_id=<logical-port-id>”
    The logical partition can be either in the running or shut down state.
  • To enable an SR-IOV logical port, type the following command from the HMC command line:
    chhwres -m <managed-system> -r sriov --rsubtype logport -o e [-p <partition-name> | --id <partition-ID>]
 -a “adapter_id=<adapter-id>,logical_port_id=<logical-port-id>”
    The logical partition can be either in the running or shut down state.
  • To verify whether SR-IOV logical ports are enabled or disabled, type the following command from the HMC command line:
    lshwres -m <managed-system> -r sriov --rsubtype logport [--filter "<filter-data>"] –level <type>
     [-F [<attribute-names>] [--header]]
    If the value of the is_disabled attribute is 0, the SR-IOV logical ports are enabled. If the value of the is_disabled attribute is 1, the SR-IOV logical ports are disabled.
