Note This problem also occurs when you create a new Storage Group, and then you try to mount the new database.

1. Click Start, click Run, type cmd, and then click OK.
2. At the command prompt, type the following command, and then press ENTER:
   cluster res Storage Group/Database (Exchange_CMS_Name) /priv

   For example, if Storage Group 4 is the nonworking Storage Group and if ExchangeCCR is the name of the clustered mailbox server (CMS), type the following command:

   cluster res Storage Group 4/Database4 (ExchangeCCR) /priv

   Note This command gives you information for the affected Storage Group. Note whether there is value information that is populated for the DatabaseGuid, StorageGroupGuid, and Network Name properties.

3. Compare the information for a working Storage Group with the information for the nonworking Storage Group.

   The following is sample information for a working Storage Group and for a nonworking Storage Group.

   Working Storage Group

   Listing private properties for 'Storage Group 10/Database10 (ExchangeCCR)': T  Resource                    Name                              Value-- --------------------------- --------------------------------- -----------------------S  Storage Group 10/Database10 (ExchangeCCR) DatabaseGuid         9c7d918b-8916-40c3-954f-2297ff7948faS  Storage Group 10/Database10 (ExchangeCCR) StorageGroupGuid     1b9333f7-5582-45c0-8b73-efc28a945604S  Storage Group 10/Database10 (ExchangeCCR) NetworkName          ExchangeCCRS  Storage Group 10/Database10 (ExchangeCCR) LatestOfflineTime    0S  Storage Group 10/Database10 (ExchangeCCR) LastMountedOnServer  Node Name

   Nonworking Storage Group

   Listing private properties for 'Storage Group 4/Database4 (ExchangeCCR1)': T  Resource                  Name                            Value-- ------------------------- ------------------------------- -----------------------S  Storage Group 4/Database4 (ExchangeCCR1) DatabaseGuid                   S  Storage Group 4/Database4 (ExchangeCCR1) StorageGroupGuid               S  Storage Group 4/Database4 (ExchangeCCR1) NetworkName 

   Note In the nonworking Storage Group example, there is no value information for the DatabaseGuid, StorageGroupGuid, and NetworkName properties. If you try to mount the database of this nonworking Storage Group, the database is not mounted, and you receive the error messages that are mentioned in the Symptoms section. This problem may occur when you use the Cluster Administrator instead the command shell to re-create instances multiple times.

4. Register the value information for the DatabaseGuid, StorageGroupGuid, and Network Name properties of the nonworking Storage Group. To do this, follow these steps:
   1. Click Start, click Run, type cmd, and then click OK.
   2. At the command prompt, type the following command to register the value for the DatabaseGuid property, and then press ENTER:
      cluster res Storage Group/Database (Exchange_CMS_Name) /priv Databaseguid=guid

      For example, assume that Storage Group 4 is the nonworking Storage Group, ExchangeCCR is the name of the clustered mailbox server (CMS), and the DatabaseGuid property value is 20e668c6-e4c6-4511-8c50-ca1f9805823c. In this scenario, type the following command:

      cluster res Storage Group 4/Database4 (ExchangeCCR) /priv DatabaseGuid=20e668c6-e4c6-4511-8c50-ca1f9805823c
   3. At the command prompt, type the following command to register the value for the StorageGroupGuid property, and then press ENTER:
      cluster res Storage Group/Database (Exchange_CMS_Name) /priv StorageGroupGuid=guid

      For example, assume that Storage Group 4 is the nonworking Storage Group, ExchangeCCR is the name of the clustered mailbox server (CMS), and the StorageGroupGuid property value is f0cc8edb-83a3-4397-8ba9-e52dfd4ed9aa. In this scenario, type the following command:

      cluster res Storage Group 4/Database4 (ExchangeCCR) /priv StorageGroupGuid=f0cc8edb-83a3-4397-8ba9-e52dfd4ed9aa
   4. At the command prompt, type the following command to register the value for the Network Name property, and then press ENTER:
      cluster res Storage Group/Database (Exchange_CMS_Name) /priv NetworkName=value

      For example, assume that Storage Group 4 is the nonworking Storage Group, ExchangeCCR is the name of the clustered mailbox server (CMS), and the NetworkName property value is ExchangeCCR. In this scenario, type the following command:

      cluster res Storage Group 4/Database4 (ExchangeCCR) /priv NetworkName=ExchangeCCR
   5. At the command prompt, type exit, and then press ENTER.

   Note To determine the values for DatabaseGuid and StorageGroupGuid properties, use the LDP GUI tool (LDP.exe).

5. Replicate the domain controllers. After the domain controllers are replicated, the previously nonworking Storage Group database can be mounted.
