Installing deduplication 43
Replacing the deduplication storage server host computer
For the new host, you must use the same host name. The new host cannot host a deduplication storage server already.
Reasons to replace the host include a lease swap or perhaps the current deduplication storage server host does not meet your performance requirements.
Warning: The new host must use the same byte order as the old host. If it does not, you cannot access the deduplicated data.
In computing, endianness describes the byte order that represents data: big endian and little endian. For example, Sun SPARC processors and Intel processors use different byte orders. Therefore, you cannot replace a Solaris SPARC host with a host that has an Intel processor.

Change the disk volume state and disk pool state to DOWN
Configure the new host so it meets deduplication requirements
Move the storage to the new host.
Install the NetBackup media server software on the new host
Delete the NetBackup Deduplication Engine credentials

See the NetBackup Installation Guide for UNIX and Linux.
See the NetBackup Installation Guide for Windows.
If you have load balancing servers, delete the NetBackup Deduplication Engine credentials on those media servers. On each load balancing server, run the following command:
See “Deleting credentials from a load balancing server” on page 75.
Add the credentials to the storage server
Add the NetBackup Deduplication Engine credentials to the storage server.
