Overview
SnapServer Manager (SSM) is a Java-based application that runs on all major client platforms. SSM provides a single screen from which administrators can discover all
SnapServers and REO 4600 appliances on their network, and launch an external application or browser for configuration and management. Additionally, SSM can monitor, upgrade, and configure network and administrative settings on one or more GuardianOS servers simultaneously.
This section is divided into sub-sections that provide the key processes and configuration options needed to maximize your usage of SnapServer Manager:
•
– Provides technical specifications and tips you need to know before you begin using SSM.
•
SnapServer Manager Main Window
– Shows how to select the GuardianOS servers you want to administer with SSM, then navigate to Administration > Administer
Servers .
•
– Covers the multiserver and single-server functions available for
GuardianOS servers in SSM.
•
– Explains how SSM discovers and maintains contact with SnapServers and REO 4600 appliances. This section is of particular interest to administrators who plan to install SSM on a laptop.
•
Customizing the SSM Interface – Provides advanced procedures for creating Server
Groups and customizing the Server Details list.
•
Usage Scenarios for GuardianOS Servers – Shows common scenarios providing the
fastest way to learn how to use SSM.
Tips and Requirements
Consider the following technical tips and requirements when deploying SnapServer
Manager on the network.
Normalize Admin Passwords for Server Groups (GuardianOS servers only)
Before you can configure a server group, SnapServer Manager asks for the admin password for each server in the group. If the servers in the group have different passwords for the admin account, you will have to remember and enter the password for each server in the group before you can perform any operations. Normalizing the password for the admin account for each server group allows you to gain administrative access to all servers in the group by entering a single password.

SnapServer Manager GuardianOS 7.1 Users Guide Features List
The Tell me more link in the banner opens the Server Software Updates dialog, listing servers for which an update is available, the version of GuardianOS each server is currently running, and the version to which each server could be updated.
Tip: You can choose to hide the banner by clicking the Remind me later or Hide this message link on the banner. If Remind me later, the server will display the banner after the next check for updates; if Hide this message, the server will hide the banner for the update in question until a later version is released.
Features List
SnapServer Manager can be used to discover SnapServers and REO 4600 appliances; however, status monitoring and advanced multiserver and single-server administration functions are available only for GuardianOS SnapServers.
GuardianOS-Only Features
The following functions are available for only GuardianOS SnapServers. For information on how to perform the multiserver operations summarized below, see “Usage Scenarios for
GuardianOS Servers” on page 1-12 .
Registering One or More Servers
To register multiple GuardianOS servers, select the servers in the SSM screen, and then select Administration > Register Servers. A separate browser window opens to a product registration form in which some of your product information may already be entered.
Simultaneous Application of Settings to Server Groups
SnapServer Manager allows administrators to organize servers into functional groups and to apply configuration modifications simultaneously to all GuardianOS servers within a group. For example, administrators can configure domain and other network settings for any number of SnapServers in one operation and be confident the settings are consistently applied across servers.
Comparing Settings Across Servers
SnapServer Manager can compare settings across any number of GuardianOS servers and identify when settings differ among servers. For example, comparing protocol access configuration for a group of servers may reveal that settings are consistent for Windows,
NFS, and AFP but that differences exist among servers in HTTP/HTTPS and FTP/FTPS settings.
Assigning IP Addresses to SnapServers on a Network Without a DHCP Server
By default, SnapServers are preconfigured to use DHCP to acquire an IP address at startup. If a SnapServer cannot find a DHCP server on the network, you may not be able to access the server. SSM discovers all SnapServers on its local subnet using a proprietary multicast communication mechanism.
To set a static IP address, right-click the server name in the Server Details list and select
Set IP Address.

Copying Settings from One Server to One or More Different Servers
SnapServer Manager can copy selected settings (TCP/IP, SNMP, SMB access, etc.) from any GuardianOS server to one or more different GuardianOS servers. See
“Current Settings for Servers”
.
Scheduling Operations to Run During Off-peak Hours
Operations can be scheduled to run on multiple GuardianOS servers during off-peak hours.
Chapter 3, “Apply Schedule (Start Later)” .
Automatic Email Notification of Completed Operations
SnapServer Manager can automatically create and send an operations report (CSV format) upon the completion of any operation. See
Chapter 3, “Operations Report”
.
Monitoring Server Status
The color coding of server and group names alerts administrators to warning and fault conditions on a server. To view detailed status information, double-click the server row in
the SSM screen. See “Server Column Status Icons” on page 1-3
.
Software Update Notification
SnapServer Manager is configured to check daily for available updates to the GuardianOS and to display an alert at the top of the Server Details list when updates are available.
To force SSM to check for available updates immediately, click Administration > Check for
Server Software Updates. SSM will connect to the remote software update server, search for applicable updates for all of the discovered servers, and display them in the Server
Software Updates dialog box.
Features Common to All Platforms Supported by SSM
Except where noted, the following single-unit features are available for all platforms supported by SSM.
Discovering Servers on the Network
SnapServer Manager automatically discovers all supported platforms on the same network segment and displays them in the main SSM window. Additionally, SSM discovers servers outside the local network if they have been added to the Remote Servers list. For more
information, see “Discovery” on page 1-6
.
Launching External Administration
The Web Management Interface(GuardianOS servers and SnapSAN servers) and REO
4600 GUI are browser-based applications that allow you to perform a wide range of administrative tasks on a server-by-server basis. To launch one of these tools, right-click the server name or go to the Administration menu and select Launch Web Administration.
Discovery
At startup and once per minute afterward, SnapServer Manager broadcasts a discovery request packet to its local subnet. SnapServers and REO 4600 appliances on the same network segment that receive discovery requests respond with a discovery packet
10400352-001 01/2012

W

SnapServer Manager GuardianOS 7.1 Users Guide Discovery
containing information. All other discovery activity is performed using both direct communication (unicast) and a proprietary multicast communication mechanism that does not impact other systems on the network.
When SSM sends or receives discovery packets, status LEDs at the right on the Status Bar flash according to which activity is taking place. The LED labeled “Tx” flashes whenever
SSM sends out a discovery request. The LED labeled “Rx” flashes whenever SSM receives a server discovery information packet.
You can add other SnapServers that reside outside the local network segment by entering their IP addresses in the Remote Server List (Edit > Remote Servers).
Tip: If SSM has not been able to communicate with a discovered GuardianOS SnapServer (for example, the server is offline or has just been started), that server’s IP address appears in blue and the Properties screen for that server shows Not Validated next to the IP address.
Once SSM has successfully communicated with the server, the text color of the IP address changes to black, and Validated appears on the Properties screen.
Local Discovery
A local server is one that resides on the same network segment as the machine on which
SnapServer Manager is installed. GuardianOS SnapServers regularly send multicast discovery information to their local network segment, other platforms broadcast their presence once on startup, and all platforms respond to discovery request broadcasts from
SnapServer Manager. SnapServer Manager passively listens for multicast or broadcast discovery information from supported platforms and broadcasts a discovery request packet on the local network segment in three cases: (1) at startup; (2) once per minute; and (3) when the administrator manually refreshes the information by selecting Edit > Refresh All.
Remote Discovery
A remote server is one that resides on a network segment different than the one on which
SSM resides. SSM cannot hear discovery information broadcasts from remote servers until
the administrator configures them on the Remote Servers list (see “Configuring Remote
Server Discovery Example” on page 1-7
).
SSM regularly queries servers on the Remote Servers list for discovery information. When discovered, remote servers return information about themselves, and remote GuardianOS servers also return information about any other GuardianOS servers on the same network.
As a result, only one GuardianOS SnapServer needs to be added per remote network to discover all remote GuardianOS servers. However, for non-GuardianOS platforms, each server must be added individually to the Remote Servers list. Remote SnapServers discovered in this manner display the letter R in the Discovery State column of the Server
Details list of the SSM screen, along with the name of the discovering Remote Server, if applicable.
Tip: For instructions on displaying the Discover State column in the SSM screen, see
Configuring Remote Server Discovery Example
For example, assume a remote network segment contains six servers:
• REO 4600 running the latest REO 4600 GUI (non-GuardianOS)
• SnapServer DX2 running GuardianOS 7.1
• SnapSAN S2000 running SnapSAN 4.3 (non-GuardianOS)
• SnapServer 410 running GuardianOS 5.2

©2010-11 Overland Storage, Inc.
W
1-7
SnapServer Manager GuardianOS 7.1 Users Guide Customizing the SSM Interface
• SnapServer N2000 running GuardianOS 6.5
To enable SnapServer Manager to discover all these remote servers, the IP address of one of the GuardianOS SnapServers needs to be entered in the Remote Servers List to discover the other two GuardianOS servers. The three non-GuardianOS platforms must be added individually. Using a GuardianOS SnapServer as a remote discovery server makes the administrator’s configuration task easier and reduces the network traffic required to refresh server status.
Tip: For full interoperability, Overland recommends that all GuardianOS SnapServers on the network run the same version of the SnapServer software. If you have SnapServers running different versions of GuardianOS on your network, use a server running the most current version as the remote discovery server.
Laptop SSM Installation and Remote Server Discovery
Unexpected results may occur in instances where SnapServer Manager is installed on a laptop that is moved from one network segment to another. In this situation, the servers that were previously in SSM’s local segment are now in a remote segment, and since no remote server has been designated in that segment, SSM can no longer hear their discovery information broadcasts. Thus, when SSM is started up in the new location, these servers will display as offline.
To Ensure All Servers Display Correctly in the SSM Screen
SnapServer Manager offers three methods to ensure all servers display correctly in the
SSM screen. The first option is the preferred method (available only if all servers are
GuardianOS servers) because this method results in less network traffic than the other options; but any combination of methods can be used to suit your environment.
Procedure Result
Add one GuardianOS (v. 2.6 or higher) SnapServer from every network segment (including the current local segment) to the Remote Servers List.
This option is applicable only if all servers on the remote network are
GuardianOS
servers.
For non-GuardianOS servers, manually add each server to the Remote Servers List.
SSM sends out only a single DRP for each server on the Remote
Servers List.
From SSM, select Edit > Options. Select the Auto-scan servers not on Remote Server list option, and click OK.
This option instructs SSM to directly (and regularly) send
DRPs to all previously discovered servers that are neither:
(1) specified on the Remote Servers list, nor (2) resident on the same network segment as a server specified on the
Remote Servers list.
SSM sends out a single DRP for each server on the Remote
Servers List.
SSM sends out one DRP for each previously discovered server, resulting in increased network traffic.
Customizing the SSM Interface
At startup, the SnapServer Manager displays all SnapServers and REO 4600 appliances discovered on the local subnet as well as any remote supported platforms configured by the administrator. The default group <All Servers> contains all discovered servers. Additional

server groups can be created for easier multiserver administration. Clicking a server group displays only the group’s servers in the Server Detail list. Click the group name to show all the servers under the name in the Server Details list.
Tip: The Status Bar indicates the status of any running or scheduled operations. Operations are defined as administrative tasks (for example, changing TCP/IP settings or configuring email notification) that are run concurrently for a group of servers.
Server Groups
SnapServer Manager allows administrators to organize servers into groups for ease of administration. Different server groupings can be created, saved, and shared with other administrators.
Server Group Color Coding
The folder color of a server group reflects the highest level of alert for any of the servers in the group.
Tip: Only GuardianOS servers display the warning and failure color codes. A group with only non-GuardianOS servers will always be color-coded grey.

The following Mac OS X image shows a server group group1 that contains multiple servers.
The group folder is yellow because one or more GuardianOS servers contain a warning-level condition associated with them. The <All Servers> folder above group1 is red, indicating a failure-level condition on at least one GuardianOS server in that group. A grey folder next to group3 indicates none of the servers in the group show warning or failure indicators.

SnapServer Manager GuardianOS 7.1 Users Guide Customizing the SSM Interface
Saving and Distributing Server Groups
Administrators who manage SnapServers from different machines will want to have the same group structures available from each SSM installation. Server groups can be saved to an XML file by highlighting the group to be saved and selecting File > Save Groups As. By default, this file is saved to the home directory for your platform.
For example, on a machine running Windows XP, the default home directory would be similar to the following:
C:\Documents and Settings\username\ssm_groups.xml
To share groups, copy the XML files to an appropriate directory on any other machines used to manage SnapServers. Alternatively, you can select File > Open Groups and navigate to the desired file.
Remove Offline Servers
Select Edit > Remove Offline Servers to remove offline servers from groups. An Include all subgroups check box on the Confirmation dialog allows you to remove offline servers from the subgroups of the selected group also. The subgroup removal option is checked by default and is disabled (grayed) if the selected group has no subgroups.

Usage Scenarios for GuardianOS Servers
This section provides scenarios of the major types of operations you can perform on multiple
GuardianOS servers. Operations can be run immediately or be scheduled to run at a later time. SSM can also automatically deliver reports on completed operations by email. Review these scenarios to quickly learn the steps required to perform each of these operations:
•
Viewing GuardianOS Server Settings/Generating a Report
•
Configuring Multiple GuardianOS Servers/Setting Up Email Notification
•
Copying Settings Among GuardianOS Servers
•
Scheduling an OS Update for Multiple GuardianOS Servers
Tip: If servers within a group have different passwords, you will have to remember and enter each password before you can administer the server group. For ease of administration, configure servers within a group with the same password.

SnapServer Manager GuardianOS 7.1 Users Guide Server Name
Server Name
Check the Server Name option to name/rename the servers. If any of the selected servers are currently members of a Windows domain, then you must rejoin the domain.
When configuring a single server, the name you enter in the Server Name field is applied to the server. When configuring multiple servers, the name you enter in the Server Name field is used as the basis for the name of each of the servers in the group, and a number differentiating each server is added by the auto-increment feature.
To change servers that are currently members of a Windows domain, changing the server names will require rejoining the domain. Enter an administrator user name and password of a user in this domain with administrative privileges. If a server that has been selected is not a member of a domain, the administrator name and password fields will be ignored.
Options Description
Server Name The default server name is SNAPnnnnnn, where nnnnnn is the unique server number (for example, SNAP242424).
SnapServer names are limited to 27 alphanumeric characters. You can also use the dash (-), underscore (_) between characters, and spaces.

SnapServer Manager GuardianOS 7.1 Users Guide FTP/FTPS
• NIS identifies users by UID, not user name, and although it is possible to have duplicate user names, Overland Storage does not recommend this configuration.
• If you join the SnapServer to an NIS domain, consider the following guidelines
• The SnapServer does not recognize users or groups who have identification numbers less than 100.
• Each UID or GID must be unique.
• You should not define a UID or GID that has been previously assigned, and you cannot define a UID or GID that is currently assigned.
Specify Client Access
As a security measure, list only users who need access, rather than allowing all NFS clients access to SnapServer shares.
FTP/FTPS
FTP/FTPS clients can access the server using local users or the anonymous account. The anonymous user is mapped to the SnapServer's local guest user account. Administrators can set share access for anonymous FTP/FTPS users by granting either read-write (the default access) or read-only access to the guest account on a share-by-share basis. For more granular control over FTP/FTPS access, administrators must create local user accounts for
FTP/FTPS users.

Select to enable (or clear to disable) access to this server via the secure FTPS protocol.
When you allow anonymous user access, FTP/FTPS users employ an email address as the password. When you disallow anonymous access, only FTP/FTPS users who are configured as local
SnapServer users can access the server.
• Select this option to allow users to connect to the server using the anonymous user account. The anonymous user is mapped to the SnapServer's local guest user account. Administrators can set share access for anonymous FTP/FTPS users by granting either read-write (the default access) or read-only access to the guest account on a share-by-share basis.
• Clear this option to prevent anonymous user access. FTP/FTPS users can may still log in via a locally created user name and password.
SNMP
The Simple Network Management Protocol (SNMP) views a network as a collection of cooperating, communicating devices that consists of managers and agents. The SnapServer can act as an SNMP agent. Once SNMP is enabled on a SnapServer, SNMP managers can access management data on the server from MIB-II and the Host Resources MIB.
Supported Network Manager Applications
You can use any network manager application that adheres to the SNMP V2 protocol with
SnapServer. The following products have been successfully tested with SnapServers: CA
Unicenter TNg, HP Open View, and Tivoli NetView.
Default Traps
A trap is a signal from the SnapServer informing an SNMP manager program that an event has occurred. The SnapServer supports the following default traps:

SnapServer Manager GuardianOS 7.1 Users Guide Options
Display No-Link Status Warnings for Ethernet Ports (GuardianOS only)
SSM is set by default to display a warning status if one of a server’s Ethernet ports has no link. With this feature activated, you can quickly see all servers with no-link status
Ethernet ports (such as, unplugged Ethernet cables). You may wish to disable the no-link status feature if you have servers with only one connected Ethernet port. To disable the feature, uncheck the Display warning if any of a server’s Ethernet ports has no link check box, and click OK.
Activate Auto-scanning of All Remote Servers
When SnapServer Manager is installed on a laptop that is moved from one network segment to another, some remote servers may appear to be offline when they are in fact online. The Auto-scan servers not on Remote Servers list option ensures that discovery works properly by sending discovery request packets to each server discovered in a previous session; this solution does, however, increase network traffic. To activate auto-scanning, select the check box and click OK.
Use an HTTP Proxy Server (GuardianOS only)
In environments that use an HTTP proxy server for external web-based communication,
SSM must be configured to use the proxy for online server registration. Check Use a proxy server for HTTP communication, enter the name or IP address of the proxy server in the Proxy host field, and enter the port used by the proxy server in the Proxy port field.
Enable Automatic Update Notification (GuardianOS only)
SSM is configured by default to check daily for available updates to the GuardianOS. When an update is found, an alert displays in a banner at the top of the SSM main window. The
Tell me more link in the banner opens the Server Software Updates dialog, listing servers for which an update is available, the version of GuardianOS each server is currently running, and the version to which each server could update.
Tip: You can choose to hide the banner by clicking the Remind me later or Hide this message link on the banner. If Remind me later is selected, the server will display the banner after the next check for updates. If Hide this message is selected, the server will hide the banner for the update in question until a later version is released.
To disable this feature, uncheck the Enable Automatic Update Notification check box and click
OK.

Set IP Address
By default, SnapServers are preconfigured to use DHCP to acquire an IP address at startup. If a SnapServer cannot find a DHCP server on the network, it will default to an address of “ZeroConf,” and you may not be able to see the server on your network. In this case, the Set IP Address feature can be used to assign a fixed IP address to the server.
NOTE: GuardianOS 6.0 and earlier servers will show 10.10.10.10 as the IP address in this case rather than ZeroConf.
Set IP Address is only available for servers that are configured for DHCP and have not received an IP address from a DHCP server.
Set a Server’s IP Address
1. In the SSM main screen, select a server.
2. Right-click the server, and select Set IP Address.
3. Enter the following required information in the TCP/IP Addressing fields:
• IP address
