Managing Veritas Data Deduplication using the Access CLISH

This section describes the various operations that you can perform on the deduplication server using the Access CLISH.

To change the user password

You can change the password of the deduplication server user.
To change the password, enter the following:
```
Dedupe> passwd user_name 
```
You are prompted to enter your current password and the new password. After you confirm the new password, the password gets updated.

Note:

If the user is not present on NetBackup, you have to add the user on the NetBackup server.
```
# /usr/openv/pdde/pdcr/bin/spauser -a -u user_name
```
You also must update the password on NetBackup if you have updated the password for the Veritas Data Deduplication server from Access Appliance.
```
# /usr/openv/volmgr/bin/tpconfig -update -stype PureDisk 
-storage_server IP address -sts_user_id user_name
```

To start the deduplication storage server

The storage server starts on the node on which the virtual IP, which you specified in the dedupe config command is online.
To start the deduplication storage server, enter the following:
```
Dedupe> start  
```
The deduplication storage server should be already configured before you start the deduplication storage server.

To display information the deduplication storage server

To display information about the deduplication storage server, enter the following:
```
Dedupe> show  
```
The information includes the file system(s) being used, the IP, and the cluster node on which the server is running.

To display the deduplication storage server statistics

To display the deduplication storage server statistics, enter the following:
```
Dedupe> stats  
```
The information includes details like total storage size, free storage, and deduplication ratio. The deduplication storage server should be online for this operation.

To show the status of the deduplication storage server

To show the status of the deduplication storage server, enter the following:
```
Dedupe> status  
```
The information includes details such as whether the server is running and the cluster node on which the server is running.

To stop the deduplication storage server

To stop the deduplication storage server, enter the following:
```
Dedupe> stop  
```
The deduplication storage server must be configured and running. If any backup job is running when the server is stopped, the job aborts with an error.

To increase the storage capacity of the deduplication storage server

To increase the storage capacity of the deduplication storage server to the given size, enter the following:
```
Dedupe> grow size 
```
The deduplication storage server should be online for this operation.

Note:

The shrink operation is not supported. You cannot shrink the size of the deduplication storage server pool after configuration.

To add a new user to the deduplication storage server

To add a new user to the deduplication storage server, enter the following:
```
Dedupe> adduser username 
```
The user name that is mentioned here is the NetBackup media server user name which you use later to configure the storage server on the NetBackup server.

To show the list of users of the deduplication storage server

To show the list of users of the deduplication storage server, enter the following:
```
Dedupe> listuser  
```

To unconfigure the deduplication storage server

Ensure that you make a note of the following configuration details before you unconfigure the Veritas Data Deduplication server. These details are required when you reconfigure the service.

The virtual IP that you used to configure the Veritas Data Deduplication serve.
Credentials to access the Veritas Data Deduplication server

To unconfigure the deduplication storage server, enter the following:
```
Dedupe> unconfig destroy_fs=yes/no 
```
The destroy_fs is an optional parameter with default value set to no.
If destroy_fs=no, the file systems that are used in the deduplication configuration (both data and catalog file systems) are not destroyed. You can later reconfigure deduplication using the same file systems.
If destroy_fs=yes,:
- If WORM was configured, a check is made to see if there are any backup images present in the system. If backup images are present, you cannot destroy the file system and the dedupe unconfig command fails. Before you unconfigure Veritas Data Deduplication and destroy the file systems, ensure that you have removed the storage unit, disk pool and storage server from the NetBackup primary server.
- If WORM is not configured, the file systems are destroyed after unconfiguring deduplication.

To add an IP to the deduplication cluster

To add an IP to the deduplication cluster, enter the following:
```
Dedupe> addip IP 
```

To remove an IP from the deduplication cluster

To remove an IP from the deduplication cluster, enter the following:
```
Dedupe> removeip IP  
```

To change the primary IP of the deduplication server, enter the following:
```
Dedupe> changeip IP config_name
```
The config_name is the name of the deduplication server to which IP is being added. It must be specified if more than one deduplication server is configured on the cluster.

To add an FQDN to the deduplication server

The FQDNs of the NetBackup master and media servers should be added to the deduplication server. This configuration leads to faster backups on the storage server and should be done prior to adding the storage server in the NetBackup administration console or Web UI. Adding the FQDNs of the NetBackup servers allows for faster name resolution within the docker container.

Do not add the IP and FQDN of the deduplication service to the deduplication server as this can create issues when the MSDP services are started.

To add an FQDN to the deduplication cluster, enter the following:
```
Dedupe> fqdn add IP	fqdn 
```

To remove an FQDN from the deduplication cluster

To remove an FQDN from the deduplication cluster, enter the following:
```
Dedupe> fqdn remove IP 
```

To grow the catalog file system of the deduplication server

To grow the catalog file system of the deduplication server to a specific size, enter the following:
```
Dedupe> catgrow size
			
```
The deduplication server should be online for this operation. This operation is not supported from the Access Appliance GUI.

You can use the dedupe catgrow <size> command to grow the catalog file system to the specified size. The default dedupe grow command does not modify the size of the catalog file system. If there are multiple data file systems, specify the file system names in the same order in which you specified them in the dedupe show command previously.

See the dedupe man page for more information.
