Troubleshooting
- 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.

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:
- The first character of the hexadecimal number = the HDS "CU" number
- 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:
- On the Web Client user interface Physical View tab, click on the Properties button.
- 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.

The Plug-In Registration Wizard prompts for the following information; organize it beforehand to save time:
- Serial number of the 9900 Series RAID Array that
you want to scan.
- Name or address (including port number) of the
HiCommand Server that communicates with the 9900 Series RAID Array (for
example, hicommandserver.engineering.xyzcompany.com:2001 or
12.23.34.45:2001).
- Valid user name to access the HiCommand Server.
- Valid password to access the HiCommand Server.
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.
You receive a warning from the Plug-In Registration Wizard, if you need to exclude the HiCommand Server's name from the HTTP Internet Proxy Servers. 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.

You can run the Plug-In Registration Wizard in one of the following ways:
- At the end of a plug-in installation, in the Installation Complete dialog box, select the check box
labeled Run the registration utility to register this plug-in with the
Capacity Reporter Server.
If you select this option,
the installation procedure runs the Plug-In Registration Wizard for you before
exiting.
- Click the Start button, and then click Programs > Storage Resource Manager Plug-In Registration, and select SRM Plug-In for 9900 Series RAID Array.
Note: You must run the Plug-In Registration
Wizard once for each unmanaged object that you want to register with the Capacity
Reporter Server.

The Plug-In Registration Wizard is self-explanatory. The following notes merely clarify
the information you need to enter.
When registering a 9900 Series RAID Array with the Capacity Reporter Server, enter the following information in the Required Registration Information dialog box:
- RAID Array's Serial Number
— The 9900 Series RAID Array's serial number (for example, 60612).
- Proxy Agent Name - Name
of the Capacity Reporter Agent computer on which the plug-in is installed.
- SRM Display Name — Name
of the 9900 Series RAID Array that you want to be displayed in Capacity Reporter
reports. This name is arbitrary; it can be any name that has meaning in your
enterprise storage network.
- HiCommand Server IP Address
- Name or address 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).
- HiCommand Server IP Port Number - Port number of the Hitachi Data Systems HiCommand™ Server that
communicates with the 9900 Series RAID Array (default =
2001).
- HiCommand Server User Name
- A valid user name to access the HiCommand Server.
- HiCommand Server Password -
The password for the HiCommand Server User Name you entered.
If you successfully registered the 9900 Series RAID Array, it is located in the group named RAID Group.
Note: When you register a 9900 Series RAID Array, Capacity Reporter passes information to the HiCommand Server in order for the HiCommand Server to 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.

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:
- Launch the software.
- Click the Options tab, and then click the Scans icon.
- In the navigation pane, click Select Proxy. The Select Proxy page is displayed.
- Next to the RAID option, click Modify. The Modify Scan
Settings for RAID page is displayed.
- 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.

You can optionally save your registration settings to a file. You might want to do this, if you are registering many unmanaged objects of the same type. To save your registration settings to a file:
- In the Required Registration Information dialog box, click Save As. The Save As dialog box is displayed.
- Enter a name for the file and give it an .SVR file extension (for example, My9900SeriesRAIDSettings.svr).
If you want to use a specific registration settings file (.SVR) when registering an unmanaged object, click Load in the Required Registration Information dialog box, and then select the appropriate .SVR file for your plug-in.

NOTE: This procedure must be performed before uninstalling Capacity Reporter.
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:
- Launch the Plug-In Registration Wizard.
- In the Registration Function dialog box, select Unregister a managed object.
- In the Required Registration Information dialog box, enter the Object Name
that corresponds to the object that you want to unmanage.
