### Plug-In Prerequisites

- The Capacity Reporter 5.0.1 (or greater) Windows NT/Windows 2000 Agent must be installed on the computer that will act as a Capacity Reporter proxy agent.
- The Capacity Reporter Agent computer must:
  - Be connected, through a TCP/IP connection, to the same network as the Hitachi Data Systems HiCommand™ Server (HiCommand Server) that communicates with the 9900 Series RAID Array.
  - Have MS Internet Explorer 5.5, SP2 with patches, or Internet Explorer 6.0 with security patches, installed.

### Useful Information

- Hitachi Data Systems HiCommand Server reports Storage Capacity Differently than Capacity Reporter
  The HiCommand Server calculates storage space as follows:

  1 KB = 1000 bytes
  1 MB = 1000 KB
  1 GB = 1000 MB
  and so on...

  The Capacity Reporter software defines 1 KB as 1024 bytes, 1 MB as 1024 KB, and so on. Because of this difference, you will see discrepancies between storage capacity reported by the HiCommand Server and Capacity Reporter for a given 9900 Series RAID Array. The actual physical storage capacity of the device does not change.
- Capacity Reporter and Hitachi Data Systems Terminology Difference
  The term "LUN" is used differently in Capacity Reporter and Hitachi Data Systems user interfaces and documentation:
  - To Capacity Reporter, LUN refers to the virtual disk rendered by the RAID Array. The Hitachi Data Systems equivalent term is "Logical Unit".
  - To Hitachi Data Systems, LUN indicates a path to a "Logical Unit".
- Capacity Reporter Plug-In for 9900 Series RAID Array Does Not Support HTTPS Communications
  The Capacity Reporter Plug-In for 9900 Series RAID Array does not support HTTPS communications to a HiCommand Server set up to operate in HTTPS mode. The plug-in does support HTTP communications.
- How to Correlate Capacity Reporter LUN Names and HDS LDEV Names
  To determine which Capacity Reporter 9900 Series RAID LUN corresponds to a particular HDS Logical Unit:
  1. The first character of the hexadecimal number = the HDS "CU" number
  2. The last 2 characters of the hexadecimal number = the HDS "Logical Unit"

  Example: If the Capacity Reporter LUN Name is 10A, the CU number is 1, and the LDEV number is 0A.

- Refresh HDS HiCommand Server Data after Changing 9900 Series RAID Array Configuration
  Each time you change the configuration of a 9900 Series RAID Array using one of the following devices, you must refresh the HDS HiCommand Server data for all HiCommand Servers attached to that 9900 Series RAID Array:
  - HDS HiCommand Server
  - HDS Remote Console PC
  - HDS 9900 Series RAID Array SVP Service Processor laptop

  Failure to refresh the HiCommand Server data can result in Capacity Reporter reporting old or obsolete 9900 Series RAID Array information.

  To refresh the data on the HDS HiCommand Server:

  1. On the Web Client user interface Physical View tab, click on the Properties button.
  2. In the new window that displays, click on the Refresh button to update the HDS HiCommand Server data.

  Note : The refresh operation takes some time to complete.

### Before You Register This Plug-In

To allow the Plug-In Registration Wizard to successfully validate the HiCommand Server name, and to allow for successful scanning, you may have to exclude the HiCommand Server's name from the HTTP Internet Proxy Servers on the computer on which you are installing the plug-in. This may be required because some proxy server configurations do not allow the HiCommand Server's default IP port communications to pass through.

If you need to exclude the HiCommand Server's name from the HTTP Internet Proxy Servers, you receive a warning from the Plug-In Registration Wizard. One of the following error messages is displayed:

- The HiCommand Server IP Address is not valid.
- The HiCommand Server could not be contacted. To enable HiCommand's GUI ability to link to SRM's GUI please re-register.

If you receive one of these error messages, go to the Proxy Settings window in your browser, and enter the HiCommand Server's name or IP address in the Exceptions field.

### Using the Plug-In Registration Wizard

Take the following steps to register one or more 9900 Series RAID Arrays with the Capacity Reporter Server:

1. Enter the following information in the Registration Utility dialog box:
   1. SRM Server Name - Name of the Capacity Reporter Server that will store information collected by the proxy agent.
   2. SRM Proxy Agent Name - Name of the Capacity Reporter Agent computer on which the plug-in is installed.
   3. HiCommand Server - Name of the Hitachi Data Systems HiCommand™ Server that communicates with the 9900 Series RAID Array (for example, hicommandserver.engineering.xyzcompany.com or 12.23.34.45).
   4. HiCommand Port - Port number of the Hitachi Data Systems HiCommand™ Server that communicates with the 9900 Series RAID Array (default = 2001).
   5. HiCommand Server User Name - A valid user name to access the HiCommand Server.
   6. HiCommand Server Password - The password for the HiCommand Server User Name you entered.

2. Click the Refresh HiCommand List button to display a list of RAID Arrays from which you can collect information.

   1. Select the RAID Arrays from which you want to collect information.

   2. Click the Register button. You can enter a user-friendly name for the RAID Array in the Display Name popup window.

      Log information displays at the bottom of the registration window.

If you successfully registered the 9900 Series RAID Array, it is located in the group named RAID Group.

Note: When you successfully register a 9900 Series RAID Array and perform a successful scan, Capacity Reporter passes information to the HiCommand Server to allow the HiCommand Server to Link & Launch Capacity Reporter from that HiCommand Server. If you no longer want to manage that 9900 Series RAID Array, you must use the Unregister a managed object function of the plug-in to remove the link to the Capacity Reporter software from the HiCommand Server GUI.

### Editing Scan Proxy Information

Using Capacity Reporter, you can edit the proxy system settings for a registered RAID subsystem. This consists of changing the Capacity Reporter Agent computer to use computer scans.

To edit scan proxy information:

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

You can change the following setting:

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 Agent computer that does not have the correct plug-in installed, all computer scans for the selected RAID subsystem fail.

### Unregistering a Managed Object

NOTES:

- This procedure must be performed before uninstalling Capacity Reporter.
- Before you can unregister a RAID Array, you must perform a scan on it.

When you register a 9900 Series RAID Array, Capacity Reporter passes information to the HiCommand Server so that the HiCommand Server can launch Capacity Reporter for that RAID array. If you no longer want to manage that 9900 Series RAID Array, you must use the "Unregister a managed object" function of the plug-in to remove the HiCommand Server GUI link to Capacity Reporter.

To unregister a managed object so that it becomes unmanaged by the Capacity Reporter Server:

1. Launch the Plug-In Registration Wizard.
2. Enter the SRM Server Name, SRM Proxy Agent, and HiCommand Server information in the Registration Utility window.
3. Click the Refresh Installed Agents button to display a list of RAID Arrays from which the Capacity Reporter software is currently collecting information.
4. Select the RAID Arrays that you want to unregister.
5. Click the Unregister button. Log information displays at the bottom of the registration window.
