### Plug-In Prerequisites

Refer to your Network Appliance Filer system documentation for information on how to verify or correct settings to meet the following requirements:

- The Capacity Reporter 5.0.1 Windows NT/Windows 2000 Agent must be installed on the computer that will act as a Sun StorEdge SRM proxy agent.
- The Capacity Reporter Agent computer should have a static or long-lease DHCP TCP/IP address.
- NetApp F720 with ONTAP 5.3
  – or –
  Other NetApp Filers with ONTAP 5.3, 6.0
- rsh must be enabled on each Network Appliance Filer that you want to scan.
- SNMP must be enabled on each Network Appliance Filer that you want to scan.
- To perform CIFS scans, enable CIFS on the Filer. To perform NFS scans, enable NFS on the Filer.

### Before You Register This Plug-In

The Plug-In Registration Wizard prompts for the following information; organize it beforehand to save time.

- The network name that the Capacity Reporter Agent and plug-in uses to contact the Filer via TCP/IP.
  Depending upon your network configuration, you might need to use the fully qualified DNS name. If you can issue a ping command from the Capacity Reporter Agent computer and reach the Filer, then the name works.
- The network name by which the Filer is known in the Windows NT/Windows 2000 domain, if applicable.
  This name is used to perform file system scans on the Filer via the CIFS protocol.
- A privileged account that has Root privileges on the Filer. The account's password is required when entering the account name.
- The Root password on the NetApp Filer.
  For successful File System Scans of the NetApp Filer you need rsh access for the Capacity Reporter Agent Login User and Server that the proxy agent is running on that will scan the NAS box. This requires Root permissions. So the Root password of the NetApp Filer is required to update the hosts.equiv file allowing that SRMUser and Proxy Agent access to the Filer.

### Using the Plug-In Registration Wizard

For general instructions on using the Plug-In Registration Wizard, see Basic Instructions for Running the Plug-In Registration Wizard.

Specific instructions for registering a Filer include:

1. When registering a Filer with the Capacity Reporter Server, you must follow these guidelines when entering information in the Required Registration Information dialog box:
   - Filer Name — Enter the Filer name as it is known on the network.
   - SRM Display Name — Enter the name of the Filer in the Windows NT/Windows 2000 domain. If you do not enter this name, you might experience failures when the Capacity Reporter Server attempts to scan the CIFS file systems on the Filer. If you experience failures, use the Modify Scan Settings for NAS page in Capacity Reporter to make the necessary changes.
2. This Plug-In Registration Wizard contains two additional dialog boxes not described in the Basic Instructions for Running the Plug-In Registration Wizard. Use the following guidelines when entering information in these dialog boxes:

   - For the Specific Registration Information dialog box
     - This plug-in requires rsh access to the NAS system. Select Allow rsh Permissions Setup if you want the registration wizard to automatically update the hosts.equiv file, which must be modified to enable rsh access. If you do not want to do this during the registration process, clear the check box and click Next to proceed with the registration.
     - Computer Name — Select the computer name or TCP/IP address to use for rsh access to this Filer.
     - Root Password for NAS System — Enter the root password for rsh access.
     - Comment to Include in Hosts.equiv File — Enter a description to include with this entry in the hosts.equiv file.
   - For the second Required Registration Information dialog box
     - Proxy Agent for CIFS Network Protocol — Enter the name of a Capacity Reporter 5.0.1 (or greater) Agent computer running on Windows NT/Windows 2000 that has the plug-in installed. This is the system used to perform remote scans of the file systems on the selected Filer using the CIFS protocol.
     - Device Network ID (for CIFS) — This field is automatically filled in with the name of the Filer that you entered in the first Required Registration Information dialog box. However, you can change or edit the entry if necessary.
     - Proxy Agent for NFS Network Protocol — Enter the name of a Capacity Reporter 5.0.1 (or greater) Agent system running on UNIX. This is the system used to perform remote scans of the file systems on the selected Filer using the NFS protocol.
     - Device Network ID (for NFS) — Enter the name of the Filer in the format by which the Sun Capacity Reporter 5.0.1 (or greater) Agent computer recognizes it. If you successfully registered the Filer, it is located in the group named Default Computer Group.
     - Privileged Account — Enter the name of an account that has Root privileges on the Filer.
     - Password — Enter the privileged account's password.

### Registration Wizard Status Messages

When you finish registering a NAS device using the NAS Registration Wizard, a potentially confusing message appears. Under the label "Setup Permission Result:", you may see a message saying the status is "failed". This does not mean the registration has failed. Check the status under the label "Registration Result:". If the status under this label reads "OK", the registration was successful.

If both status messages read "failed", check the text of the message for insight into the problem, which may include entering an incorrect user name and/or password.

### Granting the Capacity Reporter Agent rsh Permissions

Before the Capacity Reporter Server can successfully scan the Filer system for information, rsh permissions must be granted to the Capacity Reporter Agent computer that you want to serve as the proxy scan agent. You must also grant rsh permissions to the Capacity Reporter Agent Identity to connect from the system with the TCP/IP address or DNS host name of the Capacity Reporter Agent computer.

On each Filer that you want to scan, set the rsh enable feature to on. You can set rsh security through the Security options on the Filer management console. For more information, refer to your Network Appliance Filer documentation.

Note: Depending upon the configuration of your Filer and enterprise TCP/IP network, host-name resolution may not be available. If this is the case, you must enter the TCP/IP address in dotted notation for the Capacity Reporter 5.0.1 (or greater) Agent computer in order for the rsh permission check to succeed.

### Editing Scan Proxy Information

Using Capacity Reporter, you can edit the proxy system settings for a registered Filer. For example, you can change the Capacity Reporter Agent computer you want to use for computer scans, or you can set up a computer to use for CIFS- or NFS-based file system scanning.

To edit scan proxy information:

1. Launch the software.
2. Click the Options tab, and then click the Scans notebook.
3. In the navigation pane, click select proxy. The Select Proxy page is displayed.
4. Next to the NAS option, click Modify. The Modify Scan Settings for NAS page is displayed.
5. In the Select a managed object list box, select the NAS system you want to modify, and make the necessary changes.

You can change the following settings:

- Computer Scan Agent — Enter the name of a managed Capacity Reporter Agent computer that has the correct plug-in installed on it. If you select a Capacity Reporter 5.0.1 (or greater) Agent computer that does not have the correct plug-in installed, all computer scans for the selected Filer will fail.
- CIFS File System Scan Agent — Enter the name of a Capacity Reporter 5.0.1 (or greater) Agent computer running on Windows NT/Windows 2000. This is the system used to perform remote scans of the file systems on the selected NAS system using the CIFS protocol.
- CIFS Network ID — Enter the name of the Filer. This is the name by which the CIFS file system recognizes the Filer.
- NFS File System Scan Agent — Enter the name of a Capacity Reporter 5.0.1 (or greater) Agent computer running on UNIX. This is the system used to perform remote scans of the file systems on the selected NAS system using the NFS protocol.
- NFS Network ID — Enter the name of the Filer. This is the name by which the NFS file system recognizes the Filer.

### Enabling File System Scans

Although devices in this category are registered as managed computers with the Capacity Reporter Server, the file systems that are discovered during a computer scan cannot be scanned until they are enabled for scans explicitly by the user. To enable a file system scan, the Capacity Reporter user with the proper account privileges must perform the following procedure.

To enable file system scans:

1. Launch the software.
2. Click the Options tab, and then click the Scans notebook. The Select Scan page displays.
3. Select the computer group containing the NAS system from the Computer Group drop-down list box. Click Modify.
4. On the Modify Scan Settings for Computer Group page, click Scan Now.
5. Click the Resources tab, and then click the Computers notebook. The Managed Computers Report is displayed.
