IBM Tivoli Storage Manager, Version 7.1

Configure clustered environments

Depending on the applications that are installed, you can configure Tivoli® Storage FlashCopy® Manager to operate in clustered environments with SQL Server, or file system workloads.

Tivoli Storage FlashCopy Manager for SQL: Tivoli Storage Manager configuration

When you set up a clustered environment for Tivoli Storage FlashCopy Manager for SQL, use the following scenario as a guide:

On the primary system, start the Tivoli Storage FlashCopy Manager Management Console Tivoli Storage Manager Configuration wizard. Use the wizard to select application that you want to protect. For example, the SQL server.
On the Requirements Check page, in the main panel, for Cluster check, click Warnings.
In the Issue Resolution dialog, specify the path to the VSSALTSTAGINGDIR directory. You can also specify a directory on clustered storage that fails over to the node that is doing the backup.
Click OK and complete the configuration wizard. In a cluster environment, Tivoli Storage FlashCopy Manager automatically enables the Import VSS snapshots only when needed configuration option.

After you complete the configuration wizard, verify that this path is used for the Microsoft shared cluster disk. To verify the path, check the information that is stored in the dsm.opt files. For example:

# Tivoli Storage Manager backup-archive dsm.opt file
NODename variable
PASSWORDAccess generate
TCPServeraddress variable.domain.com
TCPPort variable
CLUSTERnode no
CLUSTERDISKSOnly no
VSSALTSTAGINGDIR J:\vssaltstagingdir

# Data Protection for SQL dsm.opt file
NODename variable
PASSWORDAccess generate
TCPServeraddress variable.domain.com
TCPPort variable
HTTPport variable
CLUSTERnode yes

If the VSSALTSTAGINGDIR path is not correct, edit the file to specify the correct path.

Repeat these steps on the other systems in the cluster.

Tivoli Storage FlashCopy Manager file system: Tivoli Storage Manager configuration

When you set up a clustered environment for file systems, use the following scenario as a guide:

On the primary system, start the Tivoli Storage FlashCopy Manager Management Console Tivoli Storage Manager configuration wizard. Use the wizard to configure the file system.
On the Requirements Check page, in the main panel, for Cluster check, click Warnings.
In the Issue Resolution dialog, specify the path to the VSSALTSTAGINGDIR directory.
Click OK and complete the configuration wizard. In a cluster environment, Tivoli Storage FlashCopy Manager automatically enables the Import VSS snapshots only when needed configuration option.

After you complete the configuration wizard, verify that this path is used for the Microsoft shared cluster disk. To verify the path, check the information that is stored in the options files. For example:

# Tivoli Storage Manager backup-archive client options file
NODename variable
PASSWORDAccess generate
TCPServeraddress variable.domain.com
TCPPort variable
CLUSTERnode no
CLUSTERDISKSOnly no
VSSALTSTAGINGDIR H:\vssaltstgingdir_fcm

# Tivoli Storage FlashCopy Manager file system options file
NODename variable>
PASSWORDAccess generate
TCPServeraddress variable.domain.com
TCPPort variable
HTTPport variable
CLUSTERnode yes
VSSALTSTAGINGDIR H:\vssaltstgingdir_fcm

If the VSSALTSTAGINGDIR path is not correct, edit the file to specify the correct path.

Repeat these steps on the other systems in the cluster.

Tivoli Storage FlashCopy Manager: Standalone configuration

To configure Tivoli Storage FlashCopy Manager stand-alone in a clustered environment, complete the following steps:

On the primary system, install Tivoli Storage FlashCopy Manager. When you install Tivoli Storage FlashCopy Manager on the other cluster nodes, Tivoli Storage FlashCopy Manager must be installed in the same directory on all cluster nodes. The default install directory is c:\Program Files\tivoli\FlashCopyManager.
From the MMC GUI, run the configuration wizard and configure Tivoli Storage FlashCopy Manager to protect the desired application. In a cluster environment, Tivoli Storage FlashCopy Manager automatically enables the Import VSS snapshots only when needed configuration option.
After the configuration wizard finishes successfully, close the MMC GUI.
From the command prompt, navigate to the baclient directory. The default location is c:\Program Files\tivoli\tsm\baclient.
Depending on the configuration wizard mode, either default or custom, edit either the dsm.opt or custom.opt file. Make sure the settings in the file match the following options:
```
NODename localdsmagent
PASSWORDAccess generate
TCPServeraddress flashcopymanager
CLUSTERnode no
CLUSTERDISKSOnly no
TCPCADADDRESS IP Address of your Cluster Node
VSSALTSTAGINGDIR Drive and Path of shared VSS Staging Directory
```
The VSSALTSTAGINGDIR parameter must be set to point to a cluster disk and directory that is accessible from all cluster nodes. For example: h:\vssalt
Edit the application-specific dsm.opt file to work in cluster mode. The dsm.opt file location depends on the application that is being protected. For example:
File systems and custom applications

c:\Program Files\tivoli\FlashCopyManager

Microsoft SQL Server

c:\Program Files\tivoli\tsm\TDPSQL

Microsoft Exchange Server

c:\Program Files\tivoli\tsm\TDPExchange

Make sure the settings in the file match the following options:
```
NODename Virtual Cluster Node Name
PASSWORDAccess generate
TCPServeraddress flashcopymanager
CLUSTERnode yes
VSSALTSTAGINGDIR Drive and Path of shared VSS Staging Directory
```
Make sure the VSSALTSTAGINGDIR parameter is set to the same drive and path as the VSSALTSTAGINGDIR parameter in the previous step.
Configure the Client Acceptor Daemon according to the IBM Tivoli Storage Manager Backup-Archive Clients Installation and User's Guide. The information is documented in the Configuring the backup-archive client in a Microsoft Clustered Environment topic.
Repeat these steps on the other systems in the cluster.

Troubleshooting

If problems occur during the configuration process, use the following list to identify common problems that can be easily resolved:

To correctly configure the cluster, verify that the contents of Data Protection options file that are stored on the systems in the cluster, are identical. For the Tivoli Storage Manager backup-archive client dsm.opt file, each system uses its node name as the local agent node for Tivoli Storage FlashCopy Manager. The same Data Protection or file system node name needs to be used on all of the systems in the cluster.
In the Data Protection and Tivoli Storage FlashCopy Manager dsm.opt files, verify that option for the CLUSTERNODE parameter is set to yes.
Verify that the VSSALTSTAGINGDIR path to a shared disk is set so the path can failover and be accessed by both systems in the cluster.

When you work in a cluster environment, from the command-line interface, the Volume GUID is not displayed for volumes that are clustered disks. The cluster disk is displayed.
