Demote and promote storage zones controllers

In a high availability deployment the secondary servers are independent, fully functioning storage zones controllers. To maintain or replace a primary storage zones controller, demote it first and then promote a secondary controller. If the primary server goes offline, you can promote a secondary server to primary.

Caution:

Editing the registry incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

  1. To demote a primary storage zones controller:

    1. Locate the Registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\StorageCenter

    2. Set isPrimaryConfigServer to false.

    3. Set PrimaryConfigServiceUrl to the URL of the server that will be the new primary storage zones controller, using the form https://IPaddress or https://hostname/ConfigService/.

    4. Restart the IIS server of all zone members.

  2. To promote a secondary storage zones controller:

    1. Locate the Registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\StorageCenter

    2. Set isPrimaryConfigServer to true.

    3. Set PrimaryConfigServiceUrl to http://localhost/ConfigService/.

    4. Restart the IIS server of all zone members.

  3. Modify all additional secondary storage zones controllers:

    1. Locate the Registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\StorageCenter

    2. Set PrimaryConfigServiceUrl to the URL of the server that will be the new primary storage zones controller using the form https://IPaddress or https://hostname/ConfigService/.

    3. Restart the IIS server of all zone members.
