Replacing the MSDP storage server host computer
If you replace the deduplication storage server host computer, use these instructions to install NetBackup and reconfigure the deduplication storage server. The new host cannot host a deduplication storage server already.
Reasons to replace the computer include a lease swap or perhaps the current deduplication storage server computer does not meet your performance requirements.
NetBackup recommends that you consider the following items before you recover:
The new computer must use the same byte order as the old computer.
Warning:
If the new computer does not use the same byte order as the old computer, you cannot access the deduplicated data. In computing, endianness describes the byte order that represents data: Big endian and little endian. For example, SPARC processors and Intel processors use different byte orders. Therefore, you cannot replace an Oracle Solaris SPARC host with an Oracle Solaris host that has an Intel processor.
Cohesity recommends that the new computer use the same operating system as the old computer.
Cohesity recommends that the new computer use the same version of NetBackup as the old computer.
If you use a newer version of NetBackup on the new computer, ensure that you perform any data conversions that may be required for the newer release.
If you want to use an older version of NetBackup on the replacement host, contact your Cohesity support representative.

Step | Task | Procedure |
|---|---|---|
|
Step 1 |
Expire the backup images |
Expire all backup images that reside on the deduplication disk storage. Warning: Do not delete the images. They are imported back into NetBackup later in this process. If you use the bpexpdate command to expire the backup images, use the -nodelete parameter. |
|
Step 2 |
Delete the storage units that use the disk pool | |
|
Step 3 |
Delete the disk pool | |
|
Step 4 |
Delete the deduplication storage server | |
|
Step 5 |
Delete the deduplication host configuration file |
Each load balancing server contains a deduplication host configuration file. If you use load balancing servers, delete the deduplication host configuration file from those servers. |
|
Step 6 |
Delete the credentials on deduplication servers |
If you have load balancing servers, delete the NetBackup Deduplication Engine credentials on those media servers.
|
|
Step 7 |
Configure the new host so it meets deduplication requirements |
When you configure the new host, consider the following:
|
|
Step 8 |
Connect the storage to the host |
Use the storage path that you configured for this replacement host. See the computer or the storage vendor's documentation. |
|
Step 9 |
Install the NetBackup media server software on the new host |
See the NetBackup Installation Guide. |
|
Step 10 |
Reconfigure deduplication | |
|
Step 11 |
Import the backup images |
