Reinstalling NetVault SmartDisk: an overview

In a standard NetVault SmartDisk installation, the NetVault SmartDisk software binaries are installed on a volume that is separate from the NetVault SmartDisk Storage Pools. Reinstalling the NetVault SmartDisk software binaries is required in one of the following scenarios:

•	NetVault SmartDisk is inoperable because a media failure occurred on the volume where the NetVault SmartDisk software binaries are installed.

•	The operating system of the machine where the NetVault SmartDisk Instance is running has become corrupted.

•	NetVault SmartDisk was removed. During the uninstall, the software binaries were removed, but the data stored in the NetVault SmartDisk Storage Pools was left intact.

In the preceding scenarios, the data in the NetVault SmartDisk Storage Pools is still intact and can be used by a new installation of the NetVault SmartDisk software binaries. Each NetVault SmartDisk installation of the software binaries creates a unique identity that is referenced in the NetVault SmartDisk Content Index and your backup product; therefore, it is critical that you use the following procedures to ensure that the new NetVault SmartDisk installation of the software binaries points to the original NetVault SmartDisk Storage Pools. Failure to follow these steps renders NetVault SmartDisk unable to read or restore from the original NetVault SmartDisk Storage Pools.

Prerequisites for reinstalling NetVault SmartDisk

Ensure that the following prerequisites are met before reinstalling the NetVault SmartDisk software binaries.

•	All the original Storage Pool directories, which include the directories for the Content Index, Staging Store, Chunk Index, and Chunk Store, are available in their entirety and are not corrupted.

•	All the original Storage Pool directories have been moved or copied to a different directory by using operating-system commands.

•	All the original Storage Pool directories, which are now empty, are available for the new NetVault SmartDisk software binary installation and there is sufficient available disk space to store all the data that originally resided in these directories.

•	The original identity.cfg configuration file is available. This file is located in the following directory:

…\diskmanager\etc

•	The same version of the NetVault SmartDisk software is installed that was running on the original NetVault SmartDisk installation.

Reinstalling NetVault SmartDisk if identity.cfg is available

If the original identity.cfg configuration file is available, reinstall the NetVault SmartDisk software binaries by performing the following steps:

1	Ensure that the NetVault SmartDisk non-privileged user account has full access to the original NetVault SmartDisk Storage Pool directories.

For more information, see Authentication requirements.

2	Install the same version of the NetVault SmartDisk software that was originally running.

During installation, enter the original values for the following options:

▪	Non-privileged User Account

▪	Staging Path Folder or Staging Store Directory

▪	Store Path Folder or Chunk Store Directory

For more information, see Installing the NetVault SmartDisk software.

3	Update the NetVault SmartDisk Configuration to ensure that the directory structure for the Content Index, Staging Store, Chunk Index, and Chunk Store matches the original NetVault SmartDisk installation.

For more information, see Updating the Storage Pool directory structure.

4	Stop the NetVault SmartDisk Services.

For more information, see Stopping NetVault SmartDisk Services.

5	Replace the identity.cfg file with the original file.

This file is located in the following directory:

…\diskmanager\etc

6	Use operating-system commands to copy the contents of the original Storage Pool directories, which were moved to a different directory, back to the original corresponding directories.

7	Start the NetVault SmartDisk Services.
