[Pacemaker] How to gang multiple APC AP7901 outlets together under the same name

[Epps, Josh]

Procedure: How to gang multiple APC AP7901 outlets together under the same name

Note:    Do not include any quote marks. They are used below just to indicate verbatim strings.
         It may take perhaps 10 seconds for any changes to reflect so be patient (like after clicking Apply or Next)

Here is the crm config that worked for this example (yours may be different). It worked out-of-box with no other configuration to the AP 7901.
    primitive scc-stonith stonith:external/rackpdu \
        meta target-role="Started" \
        operations $id="scc-stonith-operations" \
        op monitor interval="3600" timeout="200" start-delay="15" \
        params hostlist="scc-pri" pduip="10.1.1.50" community="private"

=== Procedure ===
Launch a web browser and key in the IP address of the AP 7901 as the URL. In this example 10.1.1.50 is the ipaddr for our AP 7901.

Here we will gang together outlets 1 and 2 under a common name "srvr-one"

>From within the APC web page, select the Device Manger tab

Click Configuration in the left pane

In the right pane, click the outlet #1 name (underlined as a link) and change its name to "srvr-one"
The external link can be any non-blank string so you can leave it as "http://www.apc.com"
Set power on delay, power off delay, and reboot duration to what you need
Click apply

In the right pane, click the outlet #2 name (underlined as a link) and change its name to "srvr-one" also
Set power on delay, power off delay, and reboot duration to match those of outlet 1
Click apply

Under "Outlet Groups" in the left pane, select Information

In the right pane, click the button "Create Local Outlet Group"

Change the Outlet Group Name to "srvr-one" -- which is the same name as both of the outlets
Check (i.e. select) the first two outlets which are now both named "srvr-one"
Click Apply

Click Next to procede to the "Select the Global Outlet for this Outlet Group" window

Check (i.e. select) only the first outlet of the two now named srvr-one
Click Apply.

You should notice " G1  srvr-one    1,2 " under the Group Name with its associated IP address

=== Test the configuration ===
In the left window pane the Device Manger tab click Control. You will see the On/Off status of all eight outlets.

Paste this into the command console to turn the two srvr-one outlets off (assuming that they are both currently on):
stonith -t external/rackpdu hostlist=srvr-one pduip=10.1.1.50 community=private -T off srvr-one

Refresh the web page (F5) and verify that both outlets are off. It may take 10 seconds for it to take.

Paste this into the command console to turn the two srvr-one outlets on (assuming that they are both currently off):
stonith -t external/rackpdu hostlist=srvr-one pduip=10.1.1.50 community=private -T on srvr-one

Refresh the web page (F5) and verify that both outlets are on.
