NetVault SmartDisk 11.4.5 - Installation Guide

Root-level or administrator account for installation: Root-level or administrator credentials are only required for use during the installation process, removal process, and, if necessary, manually restarting the NetVault SmartDisk0 Services.

•

NetVault SmartDisk Nonprivileged Group and User: Security group with full NetVault SmartDisk configuration and monitoring rights.

To create the NetVault SmartDisk Nonprivileged Group and Users, follow these guidelines:

•

For Linux and UNIX, the following examples use sdusr and sdgrp for the user and group, respectively:

If the nonprivileged group does not exist, create it.

# groupadd sdgrp

If the nonprivileged user does not exist, create it and add it to the nonprivileged group.

# useradd -G sdgrp sdusr

Define the password for the nonprivileged user.

# passwd sdusr

If the nonprivileged user does exist, add it to the nonprivileged group.

# usermod -a -G sdgrp sdusr

•

For Windows:

On Windows, you are not required to create the nonprivileged user before installation. You can enter the applicable information during the installation process. The installer verifies that the account meets all applicable system requirements before continuing with the installation process.

•

For Mac OS X:

•

Create the nonprivileged user by clicking Apple > System Preferences > Accounts. On the System Preferences dialog box, click Accounts. Use the Accounts dialog box to create a nonprivileged user.

•

Use dseditgroup to add the nonprivileged user to an applicable group. The following example uses sdusr and sdgrp for the user and group, respectively.

sudo dseditgroup -o create sdgrp

sudo dseditgroup -o edit -a sdusr -t user sdgrp

•

For Linux, UNIX, and Mac OS X:

•

If your OS does not create a corresponding nonprivileged group by default, create one and add the nonprivileged user to it.

•

After you have created the nonprivileged user and group, add your root-level or administrator account to the same nonprivileged group.

•

Enabling and configuring WebDAV authentication: During installation, you have the option of enabling authentication and configuring the credentials, specifying a user name and password. Enabling this option provides extra protection by preventing unauthorized users and backup clients from accessing the NetVault SmartDisk Instance that you are creating. That is, only clients that know these credentials can connect to the NetVault SmartDisk Instance. If you enable authentication on NetVault SmartDisk, also ensure that your backup software, such as vRanger or NetVault Backup, is able to manage the credentials; otherwise, backup jobs fail. For more information about managing WebDAV authentication in your backup software, see the documentation for the applicable backup software. If you do not enable authentication during the installation process, you can enable it later.


	NOTE: If you intend to use the NetVault Backup Use optimised replication between devices that support this feature option, available for NetVault Backup Data Copy and Duplicate operations, WebDAV authentication fails if the configured credentials are different on the source and destination NetVault SmartDisk Servers. Successful replication requires that either authentication is disabled on both instances, is enabled only on the source, or uses identical credentials on the source and destination NetVault SmartDisk Instances.

•

UNC path and credentials if using a network share on Windows: You can specify a path that includes a network share, whether it is mapped or using Universal Naming Convention (UNC). To do so, the parent directory of the target directory must exist — the target directory does not have to exist yet — and you must have the access credentials.

Important notes regarding Windows and the nonprivileged user

If you are installing NetVault SmartDisk on Windows, the NetVault SmartDisk installer grants read- and write-access permission to the specified nonprivileged user during the installation process. This access, which lets NetVault SmartDisk report Windows Events, only applies to the Application log.

If you change the nonprivileged user by using smartdisk password, the same rights are granted to the new user. The rights are retained for the original user because the original user might be assigned to multiple services on the same system. For the same reason, this access is also retained if you remove NetVault SmartDisk.

The modified registry key is:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ Eventlog\Application

Therefore, if you know that a nonprivileged user is not needed for other services, manually update the registry key and user account.

Installing the NetVault SmartDisk software

You can install NetVault SmartDisk either by using the installation CD or the package downloaded from the website.

Throughout this document, an ellipsis (…) represents the path to where you installed NetVault SmartDisk. Replace the ellipsis with the applicable information.

Important considerations

•

Installing on Linux or UNIX (excluding Solaris)

•

Installing on Solaris (SPARC, x86, or x86-64)

•

Installing on Windows

•

Installing on Mac OS X

Important considerations

•

If you are using NetVault Backup, do not install the product in the same directory as NetVault Backup is installed. If you have to remove NetVault Backup for any reason, it removes NetVault SmartDisk as well if they are installed in the same directory.


	IMPORTANT: If you are using deduplication, you cannot deploy a deduplicated instance on the same machine on which NetVault Backup Server or Client software is installed.

•

If you install NetVault SmartDisk on a double-byte Windows OS and you do not use the default directories for installation, verify that the new directories are created using single-byte characters; installation fails if you use double-byte characters.

•

You cannot install the NetVault SmartDisk binaries — installation files — on an NFS share.

•

During installation, you are prompted for two volume paths, which must be different. One volume contains the Staging Store, and the other contains the Chunk Index, Chunk Store, and Content Index. You can specify any supported File System that is listed in the Quest NetVault Backup Compatibility Guide. However, if you intend to use a third-party deduplication appliance, filer, or other form of NAS for the NetVault SmartDisk Storage Pools, you must use the network share for the appliance that is exported through Common Internet File System (CIFS) or Network File System (NFS) as the target for the Staging Store. You can specify one network share for each path during installation; if you need more shares for the Storage Pools, you can add them after installation is finished. For more information, see Completing the installation process. If the third-party appliance, filer, or NAS performs the deduplication, instead of the NetVault SmartDisk Deduplication Option, you cannot use the appliance’s network share as the target for the Chunk Store or Store Path.

Installing on Linux or UNIX (excluding Solaris)

Verify that you have reviewed the authentication requirements and all other critical information.

For more information, see Authentication requirements and Important considerations.

If you are using the CD, complete the following steps:

Insert the CD into the CD drive, and mount the drive.

Initiate a terminal session, and access the CD:

cd /cdrom/installation_files/<platform>/SmartDisk/smartdisk


	NOTE: On systems that use automount, installation fails with error message bash: ./install: /bin/sh bad interpreter: Permission denied. To avoid this issue, mount the CD manually without the noexec mount option.

If you are using the downloaded package, complete the following steps:

Using your preferred method, decompress the downloaded file.

Initiate a terminal session, and navigate to the smartdisk directory in which the decompressed files reside.

To start installation, type as root or sudo to root:

./install

With the installation successfully initiated, the setup process begins.


	NOTE: Most prompts revealed during the installation process have a default selection. These options are displayed at the end of each prompt, enclosed in brackets ([ ]). To accept a default, press Enter.

When the following prompt is displayed, type the number that corresponds to the language version that you want to install, and press Enter.

Select Language? [1]:

When the following prompt is displayed, select the applicable option.

Have you read and agreed to the terms of the license?

(y = yes, n = no, d = display license) (y n d) [d]: y

•

y: Indicates Yes. To accept the agreement, type y, and press Enter. The installation process continues without displaying the license agreement.

•

n: Indicates No. To decline the agreement, type n, and press Enter. The installation process stops.

•

d: Indicates Display. This option is the default. To view the agreement, type d, and press Enter. The license agreement is displayed in sections with a percentage value shown at the bottom of the screen. This value accounts for how much of the agreement has been displayed. Each time you press Enter, more of the agreement is displayed and this value increases. Continuously holding down the Enter key will scroll through the entire agreement, and end with the next prompt.


	IMPORTANT: Quest requires that you thoroughly review the license agreement before proceeding with the installation.

Monitor the results when the checking mechanism runs that determines if the required libstdc++ and libaio libraries are installed on the system:

•

If the required packages are installed on the system, a message is displayed and the installation continues.

Sample message:

libstdc++.so.6 is installed.

libaio.so.1 is installed.

•

If the correct version of either the libstdc++ and libaio package is not installed on the system, an error is displayed that indicates the missing library and the installation stops.

Sample error messages:

ERROR: SmartDisk requires libstdc++.so.5 to be installed.

ERROR: Please install the Compatibility Standard C++ Library package.

ERROR: SmartDisk requires libaio.so.1 to be installed on the system.

ERROR: Please install the appropriate Asynchronous I/O Access Library

package.

When the following prompt is displayed, indicate where you want NetVault SmartDisk installed.

Where should SmartDisk be installed? [/usr/smartdisk] :

When the nonprivileged-related prompts is displayed, enter the name of the nonprivileged user and the name of the user’s group:

Non privileged user? : <userName>

you chose <userName>

Non privileged user's group? [<userName>] : usergroup

you chose <userGroup>

When the additional location-related prompts are displayed, indicate where you want NetVault SmartDisk installed.


	NOTE: Linux, UNIX, and Solaris do not differentiate between local drives and mounted drives. If you choose to use a mounted drive, for example, using NFS, for the Staging Path and Store Path, Quest strongly recommends that you use a subdirectory on the applicable drive. This step ensures that data is not written to the local directory if the mounted location becomes unavailable. You must specify different physical paths for the Staging Path and Store Path.

Staging path? [/usr/smartdisk/diskmanager/stage] :

Store path? (Note: A network share located on a third-party deduplication

appliance cannot be used for the Chunk Store.) [/usr/smartdisk/store] :

If you are installing NetVault SmartDisk on Linux, enter y for Yes or n for No when the following prompt is displayed:

Would you like to configure WebDAV authentication credentials? (y n) [y]:

If you entered y, enter the applicable user name and password when the corresponding prompts are displayed, making sure to press Enter after each entry.

The installer verifies that the information you enter is correct.


	NOTE: For the user name in the WebDAV credentials, NetVault SmartDisk currently supports the use of any ASCII characters except the quotation mark ("), comma (,), and colon (:). The are no restrictions for the corresponding password.

You chose Yes.
