  4. Execute "ping" to the IPv6 of a client
  5. Bring up lustre
  6. Execute "lnetctl net show"
  7. Execute "lnetctl ping" of own NID
  8. Execute "lnetctl ping" of the client's NID
  1. "ping" of the client's IPv6 address should succeed
  2. "lnetctl net show" output should indicate an active NID featuring IPv6 address of the interface configured for use with LNet.
  3. "lnetctl ping" of own NID should be successful
  4. "lnetctl ping" of the client NID should be successful

IPv6_only.Basic.LNet.SR.1Test basic connectivity between Lustre Server and Client on LNet level. (SR, same subnet) 

Use the lustre server and clients setup in previous tests and

  1. Load "lnet_selftest" on each node
  2. Configure and run "lnet_selftest" between the nodes
  1. "lnet_selftest" should run without errors. 
  2. Throughput reported by "lnet_selftest" should be adequate (verify against link speed).


IPv6_only.Basic.Lustre.SR.1Test Lustre FS performance with the Client and Server setup to use IPv6. (SR, same subnet)

Use the lustre server and clients setup in previous tests and

  1. Mount lustre FS on the client(s)
  2. Run FIO
  1. Lustre FS mount should succeed
  2. FIO should run without errors. Throughput reported by FIO should be adequate (verify against link speed and "lnet_selftest" results).


IPv6_only.Config.MR.Client.1Configure Lustre Client using only IPv6. (MR, same subnet)
  1. Select an IPv6-enabled machine
  2. Install lustre client
  3. Configure the client to use 2 connected interfaces with only IPv6 address configured on each
  4. Bring up lustre
  5. Execute "lnetctl net show"
  6. Execute "lnetctl ping" of own NIDs
  1. "lnetctl net show" output should indicate 2 active NIDs featuring IPv6 addresses of the interfaces configured for use with LNet.
  2. "lnetctl ping" of own NIDs should be successful
