*** Notes: In no way does the ‘RetainVolumeSettings’ registry key cause the Diskeeper configuration to follow or roll-over to the Active cluster. The purpose of these instructions is to make sure each node on your Active-Passive or Active-Active cluster is configured correctly so that when a fail-over occurs, the desired Diskeeper configuration changes are present on the Active node at that time. ***
Active – Passive Cluster
1) Install Diskeeper on the Active node.
2) The Diskeeper software was designed to be installed and left to run but if it is absolutely necessary to make configuration changes such as setting a schedule, turning off IFAAST or Intelliwrite, this would be the time to do so.
3) After you have made the configuration changes, you must add the ’RetainVolumeSettings registry key to this server. To do this;
a. Run ’Regedit’
b. Create the DWORD Value;
HKLM\Software\Diskeeper Corporation\Diskeeper\UserSettings\RetainVolumeSettings
c. Give this registry key the Hex or Decimal value of ‘1’.
4) Restart the Diskeeper Service to be sure that the registry change adheres.
5) After you have completed the installation, configuration changes and setting up the ‘RetainVolumeSetting ‘ key, force a fail-over to the Passive cluster.
6) The Passive cluster will then become the Active cluster and it should see all of the volumes visible/available on the Active cluster. Install the Diskeeper software on this Passive node.
7) Open the Diskeeper GUI and replicate all of the configuration changes made on the Active node server to the Passive one.
8) Add the ‘RetainVolumeSettings’ Registry key (same as above) to the Passive node and restart the Diskeeper service.
9) Fail back over to the Active node.
10) Open the Diskeeper GUI and check to see if the configuration changes that you made initially to the Active node are still present.
11) You may also want to fail over to the passive node again to verify the settings stayed intact there.
Active-Active Cluster
1) Install Diskeeper on the first Active node.
2) The Diskeeper software was designed to be installed and left to run but if it is absolutely necessary to make configuration changes such as setting a schedule, turning off IFAAST or Intelliwrite, this would be the time to do so.
3) After you have made the configuration changes, you must add the ‘RetainVolumeSettings’ registry key retaining this server. To do this;
a. Run ’Regedit’
b. Create the DWORD Value;
HKLM\Software\Diskeeper Corporation\Diskeeper\UserSettings\RetainVolumeSettings
c. Give this key the Hex or Decimal value of “1”.
4) Restart the Diskeeper Service to be sure that the registry change adheres.
5) After you have completed the installation, configuration changes and setting up the ‘RetainVolumeSetting ‘ registry key, force a fail-over to the next Active cluster as you may have more than 2.
6) This 2nd Active cluster should now see all of the failed-over volumes that were visible/available on the 1st Active cluster. Install the Diskeeper software on this 2nd Active node and replicate all of the configuration changes made to the 1st Active node.
7) Add the ‘RetainVolumeSettings’ Registry key to the 2nd Active node and restart the Diskeeper service.
8) If you have more Active nodes in this cluster, fail-over to them one at a time and verify that they see the correct fail-over volumes. Then install the Diskeeper software and replicate the configuration changes, add the ‘RetainVolumeSettings’ Registry key and restart the Diskeeper service.
9) As you fail-over to the different Active nodes, you may also want to fail back over to verify that the settings stay intact after the failovers.
