After upgrading Enterprise Vault nodes in a Microsoft Cluster Server, registry values revert to pre-upgrade values
Problem
When Enterprise Vault (EV) resources in a Microsoft Cluster Server (MSCS) are brought back online after an upgrade, MSCS replication causes values in the EV registry key "HKEY_LOCAL_MACHINE\Software\KVS\Enterprise Vault" to revert back to pre-upgrade values.
Solution
- Go to Start | Run, type regedit, and click OK.
- Expand HKEY_LOCAL_MACHINE\Software\Wow6432Node\KVS
- Highlight Enterprise Vault, go to File > Export, and save the key to a .reg file.
- Bring the EV cluster resources online on the updated node using Cluster Administrator.
- Run the following command.
- Open Command Prompt as Administrator
- Type Cluster resource EVServername-EnterpriseVaultAdminService /check
- The checkpointing path will be seen in the output.
- Use the following command to remove the check
- Cluster resource EVServername-EnterpriseVaultAdminService /removecheck : "Software\KVS\Enterprise Vault"
6. While the services are online on the node, import the .reg file saved in step 3 by double-clicking it to overwrite the pre-upgrade values with the proper values.
7. Once the AdminService is online run the following command to add the check.
8. Cluster resource EVServername-EnterpriseVaultAdminService /addcheck:"Software\KVS\Enterprise Vault"
