10.2 iManager and Storage-Related Plug-Ins

iManager is a Web browser-based tool used for configuring, managing, and administering eDirectory objects on your network. The Storage plug-in is the primary tool used to manage NSS devices, software RAIDs, pools, and volumes.

iManager gives you the ability to assign specific tasks or responsibilities to user accounts and to present the user with only the tools (with the accompanying rights) necessary to perform those sets of tasks.

NOTE:The storage-related plug-ins do not support Mobile iManager.

This section describes the following:

10.2.1 Understanding Storage-Related Plug-Ins

Storage-related plug-ins share some management code in common. It is necessary to manage these plug-ins together when installing or updating any of the plug-ins.

Overview of the Storage-Related Plug-Ins for iManager

Table 10-2 identifies the storage-related plug-ins for iManager in OES 2 SP2 and later.

Table 10-2 Storage-Related Plug-Ins for iManager

Storage-Related Plug-In	NPM File	Role in iManager	Use to Manage
Cluster Services Management	ncsmgmt.npm	Clusters	OES Cluster Services
Distributed File Services Management	dfsmgmt.npm	Distributed File Services	OES Distributed File Services
Files and Folders Management	fileman.npm	Files and Folders	OES Files and Folders
CIFS Management	cifsmgmt.npm	File Protocols > CIFS	OES CIFS for Linux OES CIFS for NetWare
NSS Management	nssmgmt.npm	Storage	OES Storage Services
Storage Management	storagemgmt.npm	No role. Required when using any combination of storage-related plug-ins	Contains common code for all storage-related plug-ins

IMPORTANT:The storage-related plug-ins share code in common in the storagemgmt.npm file. If you use more than one of these plug-ins, you should install, update, or remove them all at the same time to make sure the common code works for all plug-ins. If you remove only one of the plug-ins, it removes the common code and breaks the remaining installed plug-ins.

Cluster Services Management

The Cluster Services Management (ncsmgmt.npm) file contains the Clustering plug-in for managing OES Cluster Services. This plug-in requires the Storage Management plug-in. The NSS Storage Management plug-in is required for cluster-enabling NSS pools and volumes.

For information about using this plug-in, see OES 23.4: OES Cluster Services for Linux Administration Guide.

Distributed File Services Management

Use the Distributed File Services plug-in to manage OES DFS for NSS volumes. The DFS plug-in also requires the NSS Storage Management and Storage Management plug-ins.

For information about using the DFS plug-in, see Distributed File Services Administration Guide for Linux.

Files and Folders Management

Provides a file tree view for managing and browsing files and eDirectory objects.

When NCP Server is installed, this plug-in supports the OES Trustee Model of access control for OES Storage Services (NSS) volumes on Linux and NetWare and for NetWare Core Protocol volumes on Linux POSIX file systems. Use it to manage the file system trustees, trustee rights, and inherited rights filters for files and folders on NSS and NCP volumes. On Linux, install the NCP Server and Dynamic Storage Technology service. On NetWare, the NCP Server service is automatically installed.

For file systems that have Volume objects in eDirectory, this plug-in allows you to upload, download, and delete files and to create and delete directories. For NSS volumes, it provides additional features that allow you to manage file system attributes, to salvage and purge deleted files and folders, and to manage directory quotas.

File Protocols Management (AFP and CIFS)

Beginning in OES 2 SP2, the File Protocols plug-in for the Native File Access Protocols for NetWare services has been replaced by two plug-ins: OES AFP (afpmgmt.npm) and OES CIFS (cifsmgmt.npm). These plug-ins support AFP and CIFS services for NSS volumes on both Linux and NetWare.

The AFP and CIFS plug-ins also require the NSS Storage Management (nssmgmt.npm) and Storage Management (storagemgmt.npm) plug-ins.

IMPORTANT:Make sure to uninstall the existing File Protocols plug-in, NSS plug-in, and Storage Management plug-in before you upgrade to these new plug-ins.

For information about managing these services, see the following guides:

OES CIFS for Linux Administration Guide

NSS Management

The OES Storage Services Management (nssmgmt.npm) plug-in allows you to manage NSS services (devices, software RAIDs, pools, and volumes). Information about using this plug-in is the focus of this guide.

Storage Management

The Storage Management (storagemgmt.npm) file contains common code that is shared by the storage-related plug-ins. If you use more than one of these storage-related plug-ins, you should install, update, or remove the storagemgmt.npm file and all installed storage-related .npm files at the same time.

IMPORTANT:If you remove any one of the installed storage-related plug-ins, it removes the common code (storagemgmt.npm) file, which breaks the remaining installed plug-ins.

Files for Storage-Related Plug-Ins

The module files (see Table 10-2, Storage-Related Plug-Ins for iManager) are located in the /var/opt/novell/iManager/nps/portal/modules/ directory.

The Java JAR files are located in the /var/opt/novell/iManager/nps/WEB-INF/lib/ directory.

The Tomcat TLD files are located in the /var/opt/novell/iManager/nps/WEB-INF/ directory.

Table 10-3 Java and Tomcat Files for Storage-Related Plug-Ins

10.2.2 Prerequisites for Using the Storage-Related Plug-Ins for iManager

The requirements in this section apply to the storage-related plug-ins for iManager that are described in Understanding Storage-Related Plug-Ins.

Web Browser Language Setting

The iManager plug-in might not operate properly if the highest priority Language setting for your Web browser is set to a language other than one of iManager’s supported languages. To avoid problems, in your Web browser, click Tools > Options > Languages, then set the first language preference in the list to a supported language.

Web Browser Character Encoding Setting

Supported language codes are Unicode (UTF-8) compliant. To avoid display problems, make sure the Character Encoding setting for the browser is set to Unicode (UTF-8) or ISO 8859-1 (Western, Western European, West European).

In a Mozilla browser, click View > Character Encoding, then select the supported character encoding setting.

In an Internet Explorer browser, click View > Encoding, then select the supported character encoding setting.

Protocols for iManager Communications

The storage-related plug-ins can be used to manage OES 2015 or later servers. Different communications protocols are required for connecting the various platforms.

Table 10-4 provides information about the protocols needed to use iManager to manage storage in a heterogeneous environment. A protocol annotated with an asterisk (*) is the default and is configured automatically on the servers. The protocols that you use must be loaded and running on both the iManager server and the target server that you want to manage.

For further clarification about WBEM, CIFS, and NCP, see the following section:

Table 10-4 Interoperability of Protocols Used to Connect the iManager Server and Target Servers

iManager Server Operating Platform	Protocol Used to Connect to the Target Server Based on Its Operating Platform (* indicates the default)
iManager Server Operating Platform	OES 1 Linux and Later	OES 1 SP1 NetWare, NetWare 6.5 SP4, and Later	OES 1 NetWare and NetWare 6.5 SP3	NetWare 6.5 SP2
OES 1 Linux and Later	WBEM	WBEM	WBEM (Start WBEM)
OES 1 Linux and Later	CIFS	CIFS	CIFS	CIFS (Field Patch 2B)
OES 1 SP1 NetWare, NetWare 6.5 SP4, and Later	WBEM	WBEM	WBEM (Start WBEM)
		NCP	NCP	NCP
	CIFS	CIFS	CIFS	CIFS (Field Patch 2B)
OES 1 NetWare and NetWare 6.5 SP3	*WBEM	*WBEM	WBEM (Start WBEM)
		NCP	NCP	NCP
	CIFS	CIFS	CIFS	CIFS (Field Patch 2B)
NetWare 6.5 SP2	Not available	NCP	NCP	NCP

WBEM

Where WBEM is the default protocol, WBEM is loaded and runs automatically when you start the server. Otherwise, you must start WBEM to use the protocol.

The storage-related plug-ins for iManager require CIMOM connections for tasks that transmit sensitive information (such as a username and password) between iManager and the _admin volume on the OES server that you are managing. Typically, CIMOM is running, so this should be the normal condition when using the server. CIMOM connections use Secure HTTP (HTTPS) for transferring data, and this ensures that sensitive data is not exposed.

If CIMOM is not currently running when you click OK or Finish for the task that sends the sensitive information, you get an error message explaining that the connection is not secure and that CIMOM must be running before you can perform the task.

IMPORTANT:If you receive file protocol errors, it might be because WBEM is not running.

To check the status of SFCB:

As root in a console shell, enter
```
rcsfcb status
```

To start SFCB:

As root in a console shell, enter
```
rcsfcb start
```

10.2.3 Downloading and Installing iManager Plug-In Updates

For information, see the iManager 3.2 website .

10.2.4 Accessing iManager

Launch a Web browser.
Click File > Open, then enter

https://server-IP-address/nps/iManager.html

The URL is case sensitive. Replace server-IP-address with the actual server DNS name or IP address. For example:
```
https://192.168.1.1/nps/iManager.html
```
The iManager Login page opens.
Use your administrator username and password to log in to the eDirectory tree that contains the server you want to manage.

In iManager, you can access only the roles and tasks you are authorized to manage. For full access to all available iManager features, you must log in as Supervisor of the tree.

10.2.5 Accessing Roles and Tasks in iManager

Access iManager, then log in to the eDirectory tree where the server you want to manage resides.

For information, see Section 10.2.4, Accessing iManager.
In Roles and Tasks, click the Storage role to expand its main tasks

As you work in the storage-related plug-ins, use the navigation links at the top of the page, referred to as “breadcrumbs,” to return to pages you recently visited, or use the links in Roles and Tasks. If you use the Refresh and Back features of your Web browser to navigate, iManager returns you to the initial page you encountered after login.
To activate the options on the selected page, select a server to manage.

For information, see Section 10.2.6, Selecting a Server to Manage.

10.2.6 Selecting a Server to Manage

Before you can access the management options on a selected task page, you must select a server to manage that is in the same NetIQ eDirectory tree where you are currently logged in.

Use one of the following methods to select a server in the tree where you are logged in:
- Type the eDirectory distinguished server name for the server you want to manage, then press Tab or click somewhere on the page outside of the Server field to enter your selection. For example:
```
svr1.company
```
- Click the Search icon to open the eDirectory Object Selector. Browse or search the list to locate the server you want to manage, then click the server name.
- Click the Object History icon to select a server you have recently managed.
Wait for iManager to retrieve information about that server and display the appropriate information to the task page you are in.

It might take several seconds to retrieve the information, depending on the size and complexity of your storage solution.

10.2.7 Storage Plug-In Quick Reference

The Storage role comprises seven key tasks:

Pools

You can create and manage storage pools to efficiently use all free space. You can also enable the Pool Snapshot feature to preserve point-in-time views of data pools and to support data backup and recovery. Snapshots are not supported for clustered pools.

10.2.8 Files and Folders Plug-In Quick Reference

The Files and Folders plug-in for iManager provides the Files and Folders role for Linux and NetWare. It is also integrated in iManager as the View Objects option in the iManager toolbar. File browsing in iManager is available for file systems that have a Volume object defined in eDirectory, such as for NSS volumes on Linux and NetWare and for NCP volumes on Linux.

The Files and Folders Manager NPM file (filemanager.npm) is automatically installed in iManager. For information about manually installing NPM files for iManager, see the iManager 3.2 website.

Click the Files and Folders role to select tasks first, then search for the file or folder you want to manage. Click the View Objects icon to view the Tree, Browse, and Search view of a server’s eDirectory objects in the left pane. In the Tree view, click a Volume object to see the hierarchical file system tree view of the volume's folders and files. Click the plus (+) or minus (-) icon next to a directory name to expand or collapse the view of its subdirectories. Locate the file or folder you want to manage, then specify the action you want to perform for it.

The Files and Folders plug-in for iManager provides the tasks described in this section. All of the tasks and actions that are available under the Files and Folders role are also available from the View Objects tree view.
