If you cannot dynamically remove the virtual function, use the static method. See Static SR-IOV.
primary# ldm list-io
primary# ldm add-io vf-name domain-name
vf-name is the pseudonym name or the path name of the virtual function. The recommended practice is to use the pseudonym name. domain-name specifies the name of the domain to which you add the virtual function.
The device path name for the virtual function in the domain is the path shown in the list-io -l output.
primary# ldm stop-domain domain-name primary# ldm add-io vf-name domain-name
vf-name is the pseudonym name or the path name of the virtual function. The recommended practice is to use the pseudonym name. domain-name specifies the name of the domain to which you add the virtual function. The specified guest domain must be in the inactive or bound state.
The device path name for the virtual function in the domain is the path shown in the list-io -l output.
primary# ldm start-domain domain-name
This example shows how to dynamically add the /SYS/MB/PCIE7/IOVFC.PF0.VF0 virtual function to the ldg2 domain.
primary# ldm add-io /SYS/MB/PCIE7/IOVFC.PF0.VF0 ldg2
If you cannot add the virtual function dynamically, use the static method:
primary# ldm stop-domain ldg2 primary# ldm add-io /SYS/MB/PCIE7/IOVFC.PF0.VF0 ldg2 primary# ldm start-domain ldg2
If you cannot use this dynamic method, use the static method instead. See Static SR-IOV.
Caution - Before removing the virtual function from the domain, ensure that it is not critical for booting that domain. |
primary# ldm list-io
primary# ldm remove-io vf-name domain-name
vf-name is the pseudonym name or the path name of the virtual function. The recommended practice is to use the device pseudonym. domain-name specifies the name of the domain from which you remove the virtual function.
primary# ldm stop-domain domain-name
primary# ldm remove-io vf-name domain-name
vf-name is the pseudonym name or the path name of the virtual function. The recommended practice is to use the device pseudonym. domain-name specifies the name of the domain from which you remove the virtual function. The specified guest domain must be in the inactive or bound state.
primary# ldm start-domain domain-name
This example shows how to dynamically remove the /SYS/MB/PCIE7/IOVFC.PF0.VF0 virtual function from the ldg2 domain.
primary# ldm remove-io /SYS/MB/PCIE7/IOVFC.PF0.VF0 ldg2
If the command succeeds, the virtual function is removed from the ldg2 domain. When ldg2 is restarted, the specified virtual function no longer appears in that domain.
If you cannot remove the virtual function dynamically, use the static method:
primary# ldm stop-domain ldg2 primary# ldm remove-io /SYS/MB/PCIE7/IOVFC.PF0.VF0 ldg2 primary# ldm start-domain ldg2
