- Issue 1
-
- Description: For custom (OEM) adapter cards based on Mellanox ConnectX-3 / ConnectX-3 Pro ICs, adapter firmware must be manually burnt prior to the installation with SR-IOV support
- Workaround: See the firmware installation instructions.
- Issue 2
-
- Description: The number of SR-IOV virtual functions supported by Mellanox adapters is up to 16 on ConnectX-3 adapters and up to 62 on ConnectX-3 Pro adapters (depends on your HW capabilities).
- Workaround: NA
- Issue 3

- Workaround: Delete port / instance and attach a new port.
- Issue 6
-
- Description: Starting large amount (>15) of IB VMs with normal port at once may result in some VMs not getting DHCP over InfiniBand networks.
- Workaround: Reboot VMs that didn't get IP from DHCP on time or start VMs in smaller chunks (<10).
- Issue 7
-
- Description: After large InfinBand deployment of more than ~20 nodes at once with Controllers HA, it might take time for controllers services to stabilize.
- Workaround: Restart openibd service on controller nodes after the deployment, or deploy with phases.
