Adding and Removing InfiniBand Virtual Functions to Root Domains

How to Add an InfiniBand Virtual Function to a Root Domain

This procedure describes how to add an InfiniBand SR-IOV virtual function to a root domain.

  1. Initiate a delayed reconfiguration.
    primary# ldm start-reconf root-domain
  2. Add one or more virtual functions to the root domain.

    vf-name is the pseudonym name or the path name of the virtual function. The recommended practice is to use the pseudonym name. root-domain-name specifies the name of the root domain to which you add the virtual function.

    primary# ldm add-io vf-name root-domain-name
  3. Reboot the root domain.

    Run one of the following commands:

    • Reboot the non-primary root domain.
      primary# ldm stop-domain -r root-domain-name
    • Reboot the primary root domain.
      primary# shutdown -i6 -g0 -y
