SR-IOV VNICs Support
SR-IOV was introduced by PCI-SIG as an industry-standard for IO
virtualization. Support for SR-IOV was added to Solaris 11 on SPARC
LDOMs platforms.
Oracle Solaris 11.2 now introduces a support for managing SR-IOV VNICs
through dladm(1M) on both SPARC and x86 platforms. On SPARC (LDOMs)
platforms, the existing LDOMs commands for managing VFs will continue to
function as before. Due to differences between dladm's and LDOMs'
management model, the LDOMs commands may not be used at the same time as
the new dladm(1M) commands.
The following commands show how to enable SR-IOV mode and create a VF
VNIC:
# dladm set-linkprop -p iov=on net0
# dladm create-vnic -lnet0 v1
Displaying SR-IOV information:
# dladm show-phys -V
# dladm show-vnic -V
To create a regular VNIC on a link with iov=on, the user can run:
# dladm create-vnic -lnet0 -piov=off v2
See dladm(1M) for additional information and examples.
SR-IOV Fiber Channel (FC) Support
Oracle Solaris 11.2 now allows to configure SR-IOV FC devices on SPARC
platforms.
FC SRIOV PF devices can be identified using the "ldm list-io" command.
The TYPE column contains the value "PF", and the NAME column contains
the string "IOVFC". The "ldm create-vf" command can be used to create
a VF.
Example: ldm create-vf [port-wwn= node-wwn=]
[bw_percent=[]] <fc_pf_name>
The "port-wwn" and "node-wwn" arguments must both be present or both be
omitted. If they are omitted, the LDoms Manager will generate valid
values which do not collide with other existing WWN values. The
"bw_percent" (bandwidth percent allocated to the new vf) has a default
value of 0. If "port-wwn" and "node-wwn" values are supplied in the
"create-vf" command, the format is similar to the colon-separted list of
hex bytes used for mac addresses, except there must be 8 bytes rather
than 6.
The "ldm set-io" can be used to modify the properties. This has the same
syntax as the "create-vf" command except that the target device is an
existing VF, rather than a PF.
