Red Hat Bugzilla – Bug 149754
Cannot configure power fencing for a node with dual power supplies
Last modified: 2015-04-19 20:46:41 EDT
Description of problem:
The GUI should provide a way of setting an option value for turning
power supplies off and on so a user can configure power fencing for a
node with dual power supplies.
Configuring power fencing for a node with dual power supplies requires
that both power supplies in the node be powered down before powering
them up. That is, the sequence should go like this:
- Power supply 1: off
- Power supply 2: off
- Power supply 1: on
- Power supply 2: on
Refer to figures and examples in the GFS 6.0 admin guide for more

Power Supply -
âExample 6-14. Node Defined for APC Fencing, Dual Power Suppliesâ -
To add the capability of configuring power fencing for a node with
dual power supplies, the GUI should include an âOptionâ field in the
Fence Properties dialog box (Cluster -> Cluster Nodes -> <node> ->
Manage Fencing For This Node -> Add a New Fence Level -> Fence Level
<n> -> Add a New Fence to this Level). The option should provide
either a drop-down box or provide validation for "off", "on", and
other options that are used for fencing.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Create cluster node "foo".
2. Navigate: Cluster -> Cluster Nodes -> foo ->
Manage Fencing For This Node -> Add a New Fence Level ->
Fence Level-1 -> Add a New Fence to this Level
3. Observe the Fence Properties dialog box. There is no way to
configure an "off" or "on" option.
Step 3, no Option field for "off" and "on"
Fence Properties dialog box provides an Option field for "off" and "on"
This is addressed in build 0.9.20-1.0
This does work assuming the user does the right thing. The user needs to create
two fences for one level and then the GUI will just "know what to do".
