Configuration Tests
| Test | Steps |
|---|
| Configure route | - Configure the gateway node with at least 4 interfaces
- Configure 2 gateway interfaces on tcp and 2 interfaces on tcp2
- Configure 2 peers. Peer A on tcp and Peer B on tcp2
- Configure a route on Peer A using the primary NID of the gateway
- Configure a route on Peer B using the primary NID on the gateway
- Show peers on Peer A and B and make sure that all 4 gateway interfaces have been discovered
|
| Verify Discovery interval | - Configure as above
- Monitor net stats "lnetctl net show"
- Verify that route is discovered every approx 60 seconds by enable the net on debug and check log(look for TRACE)
- Change the alive_router_check_interval to 30 seconds and verify router is discovered every 30 seconds
|
| Verify route UP | - Configure as above
- lnetctl route show -v
- Verify route is up on both Peer A and Peer B
|
| Verify route DOWN with avoid_asym_router_failure = 0 | - Configure as above
- "lnetctl route show -v" should show Up in stat
- set avoid_asym_router_failure = 0 on Peer A and bring it down
- Verify route stat shows Down after alive_router_check_interval on Peer B
|
| Verify multiple router | - Configure similar as above but add another router for a total of > 2 gateways
- Ensure that all routers are discovered at regular intervals of alive_router_check_interval
|
Traffic Tests
| Test | Steps |
|---|
| 1 Gateway test | - Configure similar to above with 1 gateway
- Run traffic using lnet_selftest
- Verify traffic is distributed evenly across the gateway's interfaces
- NOTE: only one route for the gateway
|
| >=2 Gateway test | - Configure multiple gateways between the peers
- Run traffic using lnet_selftest
- Verify traffic is distributed over the two gateways and their interfaces
|
| Verify hop count | - Configure multiple gateways between the peers
- Set 1st gateway to have hops = 1
- Set 2nd gateway to have hops = 2
- Run traffic using lnet_selftest
- Verify traffic is using 1st gateway. Traffic should be distributed among its interfaces
|
| Verify priority | - Configure multiple gateways between the peers
- Set 1st gateway to have priority = 0
- Set 2nd gateway to have priority = 10
- Run traffic using lnet_selftest
- Verify traffic is using 1s gateway. Traffic should be distributed among its interfaces
|
Traffic Failure
| Test | Steps |
|---|
| 1 Gateway. Multiple interfaces. Interface failure | - Configure similar to above with 1 gateway
- Run traffic using lnet_selftest
- Verify traffic is distributed among the gateway's interfaces
- Unplug one of the gateway's interfaces
- Verify traffic switches to using the other interface
|
| >=2 Gateways. Gateway Failure | - Configure similar to above with 2 or more gateways
- Run traffic using lnet_selftest
- Verify traffic is distributed among the gateways and their interfaces
- shutdown one of the gateways
- Verify that the other gateway will continue to be used
|
File System Test
Repeat the tests in the above 2 sections but instead of using lnet_selftest, bring up a file system and run IOR (or other) jobs. Verify no evictions occur during failure testing.
