Testing Results

Tests completed on 4-1-04

For all of the following tests the nodes are set to shutdown after 2 mins.

Test 1
Long power failure with idle nodes
The test effects 20 nodes

  • Pull ups power cable for nodes s101-s120
  • After all nodes shutdown plug ups cable back in.
  • Etherwake nodes. Make sure they all come back up.
Proper Result: All 20 nodes should shutdown cleanly and etherwake
Result: PASSED

- 13:17:05 the plug to s101 ups plug was pulled from wall
- 13:20:19 the last node (i.e. the masternode) halted

3min 14sec for halt

Test 2
Long power failure with idle nodes
The test effects 20 nodes

  • Pull ups power cable for nodes s081-s100
  • After all nodes shutdown plug ups cable back in.
  • Etherwake nodes. Make sure they all come back up.
Proper Result: All 20 nodes should shutdown cleanly and etherwake
Result: PASSED

- 13:22:52 the plug to s81 ups plug was pulled from wall
- 13:26:06 the last node (i.e. the masternode) halted

3min 14sec for halt

Test 3
Cut Power at breaker with nodes running heat
The test effects 20 nodes

  • Flipped power breaker for slave nodes s081-s120
  • Flip power back on at breaker after all nodes shutdown.
  • Etherwake nodes.
Proper Result: All 20 nodes shutdown and etherwake.
Result: PASSED

- 13:38:54 the breakers were flipped
- 13:42:21 the last node (i.e. the masternode) halted

3min 27sec for halt

Test 4
Flip power breaker for all slave nodes (1-296) while nodes are idle.
This test effects all 296 slave nodes.

  • Flip power breakers for all slave nodes (1-296).
  • After all nodes shutdown return power at breaker
  • Etherwake all nodes.
Proper Result: All 296 nodes should shutdown and etherwake.
Result: PASSED

Test 5
Flip power breaker for all slave nodes (1-196) while nodes are running heat.
This test effects all 296 slave nodes.

  • Startup heat on all slave nodes
  • Flip power breakers for all slave nodes (1-296).
  • After all nodes shutdown return power at breaker
  • Etherwake all nodes.
Proper Result: All 296 nodes should shutdown and etherwake.
Result: PASSED
