Take the following steps to uninstall DPX for Linux or UNIX:

1. Log in to a shell session of the Linux system that has DPX to remove, typically, by using an SSH client.

2. Run the uninstall script from <product-directory>/uninstall/uninstall_DPX with a root privilege. Typically, run the following shell command:

$ sudo /opt/DPX/uninstall/uninstall_DPX

The product version is now uninstalled.

Prerequisites

Before installing the DPX Client on Linux, review the following prerequisites:

• The minimum hardware requirements are as follows:

• Ensure your client system is included in the DPX 4.10 .

• The system resources and configurations of your client machine must meet the requirements as shown on the DPX product web page.

• Your client system must have the libnss3 plug-in. For example, you can install the libnss3 plug-in package in Red Hat Enterprise Linux 8 or supported variants of it by using the following command:

  Copy

  $ sudo yum install libnss3.so

• Your client system must have the iSCSI packages for the Instant Access (IA) mapping which is one of the features for the Block Backup of DPX. The package name and installation steps may vary. For example, you can install the iSCSI packages in Red Hat Enterprise Linux 8 or supported variants of it by using the following command:

  Copy

  $ sudo yum install iscsi-initiator-utils

• Allow all required ports for the Catalogic DPX Client:

• TCP: 3260, 6123, 6124, 9104, 9202, 10000, 10001, 10566, and 15660.

• UDP: 6123 and 6124.

Additional prerequisites

• The storage volume to install the DPX Client for Linux must be part of an LVM group.

• The physical extent (PE) of the LVM volume group to install the DPX Client for Linux must have free PE of at least 10%.

Install the DPX Client on your client machines and register these client nodes with the DPX Master Server so that DPX will be able to protect data in these client nodes. Refer to this section to install the DPX Client on either one of the following UNIX and UNIX-like systems:

• Linux

• Novell (Micro Focus) Open Enterprise Server (OES)

• IBM AIX

For Microsoft Windows, see DPX Client for Microsoft Windows.

To install the DPX Client for Linux, follow these steps:

1. Go to the Catalogic website and log in.

2. Navigate to the product page and go to Software Download > New Installations or deployments > Client Software Installation.

3. Download the Linux ISO file to your workstation.

4. Copy the ISO image file to the client system, say, the home directory (~).

5. Verify the MD5 checksum value of the ISO image file by comparing it with the value on the product web page:

6. Mount the ISO image file in the client system and go to this disk image. For example, use the following commands:

7. Run the installation program with the root privilege:

1. The installation program prompts you to read the Software License Agreement; proceed to the next step if you agree.

2. Follow the instructions to set up the configurations:

   • Product directory to install the DPX Client application (default: /opt/DPX/)

   • DPX virtualization proxy server for VMware. Enter Y if you are using DPX on the VMware environment and you want to install this proxy server program on the client machine. (default: Do not install the proxy server.)

   • Logical node name (default: the hostname of the client system)

   • Host name or the IPv4 address of the client node (default: the IPv4 address of the client system)

   • Group name. Enter the name of an existing node group to add this client node to the node group. Or, enter a new node group name so that DPX creates a new node group with this name and adds the client node to this new node group. (default: DefaultGroup)

   • Registering this client node with the DPX Master Server as part of an Enterprise. If you answer 1 for Yes, enter the hostname of the DPX Master Server. (Default: Yes). You will need to provide the following node configuration details:

     • Logical Node name (specify the name of your choice);

     • Hostname or IP address of your machine;

     • Group name for the node: enter a name of an existing node group to add this client node to the node group. Or, enter a new node group name so that DPX creates a new node group with this name and adds the client node to this new node group. (default: DefaultGroup);

     • Hostname of master server (default: localhost);

     • Registering this client node with the DPX Master Server as part of an Enterprise. If you answer 1 for Yes, enter the hostname of the DPX Master Server. (Default: Yes)

   • For Micro Focus Open Enterprise Server: enter the root password, eDirectory user name, and eDirectory password. Enter the eDirectory distinguished user name and password which contain the context of the user object.

   • Block Data Protection to create block-level snapshot backups on this client node. (default: Enable)
