Upgrading Data Manager

You cannot upgrade from the trial version to the full version. You must completely remove the trial version before installing the full version.

When upgrading to a new version of Data Manager and installing the new version in a different path, follow these steps:

  1. Uninstall the current version of Data Manager.
    1. From the Start menu, click Programs > F5 Networks > Data Manager > Uninstall Data Manager.
    2. When the screen appears asking which items to retain, leave all the checkboxes checked. In other words, retain everything.

      These items are saved in their current location; for example: <application-root-dir>\db

  2. Install the new release of Data Manager.
  3. Stop the Data Manager service.
    1. From the Start menu, click Programs > F5 Networks > Data Manager > Stop Data Manager.
    2. Copy the files you retained in step #1b to the new location; for example, the default location which is:

      C:\Program Files\F5 Networks\Data Manager

  4. Start Data Manager.
    1. From the Start menu, click Programs > F5 Networks > Data Manager > Start Data Manager.

If you upgrade your trialware version and time has not expired on the initial trialware version, you must save your database or you will invalidate the remainder of your trial period.

The Data Manager base module formerly included the Discover File Server module and the ARX Configuration module. It now includes the Discover File Server module and ARX ROI Calculator. If you find that you are suddenly missing functionality connected with ARX Configuration module, you must purchase one or more ARX model licenses. For assistance, see your SE or consult the Data Manager User's Guide section on adding or removing licenses.

NFS Support from Windows SFU

  • To support NFS, customers must install Microsoft Windows Services for UNIX (SFU). To better detect issues where customers do not install or configure SFU correctly, the collect-diags capability has been enhanced to save selected output.
  • Data Manager requires that you install Microsoft SFU to inventory NFS file systems. If SFU is not installed, Data Manager disables NFS inventory options in the GUI which, in effect, prevents the user from attempting an NFS inventory before installing SFU.
[ Top ]

Enhancements in this release

File System Inventory

  • Scan time performance enhancements. Increased overall speed when collecting statistics and reduced load on file servers.
  • Scan time throttle control. During inventory, Data Manager performs a treewalk on one or more subdirectories of the share/export to gather data. This can place an additional load on file servers. If users are concerned about this additonal load, they can now select a speed slower than the default.
  • Inventory by hostname. Users can now discover a file server by entering either an IP address or a hostname. The hostname can be either a single name (suffixed with the DNS search order of the DM server) or a fully qualified domain name.

File Server Discovery

  • Discovery by hostname.
  • RPC support for Windows remote discovery users.
  • Support for Windows 2008 file server discovery (non-clustered servers).

Licensing

  • Enforcement of ARX licenses.
  • At least one Configuration Support License key is required to enable Configuration Assistant functionality.
  • ARX Configurations Summary page and the ARX Configurations page hidden unless the customer has at least one cluster key.
  • On an upgrade, if a customer does not have the Configuration Support Licenses, access is disallowed to the Configuration Assistant functionality.

Common Operations Page

  • New category labeled Base Module. Data Manager always displays this category which includes the Discover File Server button.
  • The ARX Configuration Assistant Module category includes the Create ARX Configuration button only. Data Manager displays the button only if at least one Configuration Support License is present and enabled; for example: ARX-4000 Configuration Support License.

Report Generation

  • Save chart and graphic images in black-and-white.
  • Batch Summary reports. Select multiple inventories and then run the Report wizard once to generate individual reports for each inventory.
  • Automatically create Summary reports after an inventory task completes.
  • Include up to 500 inventory files in Cumulative reports and up to 12 inventories for Delta reports.
  • Increase limits in Delta reports to allow for graphing the 100 top items, a maximum of 10 data points in each chart, and a maximum of 10 charts.Increase limits for graphing top data elements (top extensions, top paths, top owners).
  • Limit reported data to a specified list of top extensions, top paths, or top owners.
  • Customize graphics displayed in reports (top of cover, bottom of cover, logo, copyright information).
  • ROI reports showing in detail storage infrastructure and costs with and without an ARX.

Trialware Updates

  • The trial verion's trial period has been extended to 90 days.

Other Enhancements

  • The current collect-diags facility gathers all information, including all inventory files. These files or the collection of these files may be large. To facilitate small collections, the collect facility has been enhanced to allow users some choice as to what is collected. Users can select
  • Data Manager ships on a CD with the serial number attached to the jewel case. However, the F5 support model relies on the customer?s having a serial number in hand when creating a support case. When customers call in and have forgotten where the CD case is located and cannot provide a serial number, problems can ensue. To provide a more streamlined support process, the installation process now requires customers to enter the serial number and other identifying information which is subsequently stored in the Data Manager database and automatically collected as part of the collect-diags operation. The information is also displayed when you click "!" (the About button) in the Data Manager GUI.
  • A new "Check for Updates" button has been added to the Gui Maintenance page. When the user clicks this button, version and update information is displayed.
  • Data Manager finds and reports on certain conditions in the user environment that are not ideal for or are incompatible with an ARX installation. In v2.5.0, Data Manager can now find and report on certain "problematic" or "special" files (busy files, roaming profiles, FGNs, 8.3 names, etc.) in log files that are available from the GUI Inventories page.
  • Data Manager enables users to list directories to be skipped (or "ignored") during file system inventory. Different file server types require different that different directories be ignored and Data Manager automatically fills in the correct default ignore directories for the specified file server. In addition, Data Manager saves the ignore directory list in the inventory files and displays it in the File System Inventory Details page (General tab). The ARX snapshot directory is always part of the default ignore list. You can edit the default list.
  • Inventories and reports can consume large amounts of space, and you may want to change the default locations where these files are stored. Data Manager has been enhanced to enable users to store inventories and/or reports on an alternate local (physically-attached) drive or on a remote share located on the network.
  • When cutting in an ARX. it is important to know how much space to reserve for metadata. Data Manager computes this amount of space (Approximate ARX Metadata Size) and displays it in reports (in the section "ARX Metadata Information"). This information also appears in the Inventory Details page under the Files/Dirs tab.

General notes

RPC-Based Windows Server Discovery

To perform RPC-based discovery on Windows servers, you must use a local or domain administrator account with "Log on as a service" privilege. This privilege is not granted by default. For details, see the F5 Data Manager User's Guide section on Performing RPC-Based Discovery on Windows.

Connecting to F5DM service if there is another service already running using port 443 (31815)

You cannot connect to Data Manager if there is another service already running on the machine and that service is using port 443.

If Data Manager has installed successfully, troubleshoot as follows:

  1. Verify that the Apache Tomcat F5DM service has started by checking Administrative Tools > Services.
  2. Find out which service is using port 443 from Administrative Tools > Services.
  3. Terminate that service.
  4. Restart the F5DM service.

If inventories fail when Data Manager is installed on Windows 2000, it may be because dbghelp.dll is missing.

If inventories or reports fail on Windows 2000 servers, it may be because Windows 2000 does not contain the correct version of dbghelp.dll. If so, you will see the following error message when viewing reports or inventories:

Windows dll dbgHelp must be installed on Windows 2000 to run inventory modules.

You can obtain dbghelp.dll as a part of the user mode process dumper tools provided by Microsoft:

User Mode Process Dumper Version 8.1

The file that you download is a self-extracting zip file. Locate dbghelp.dll and copy it to:

<application-root-dir>\Data Manager\bin

You do not need any other files from the downloaded zip file.

When performing discovery on an EMC Celerra, be sure the shell prompt is displaying correctly.

If you are having difficulty discovering an EMC Celerra file server, it may be due to an issue with the shell prompt. Data Manager assumes a default end character prompt of $ (dollar sign). Log in to the file server and note the shell prompt. If it does not end in $, change the .bash_profile so that the prompt does end with a $ and attempt the discovery again.

When discovering Windows servers with TELNET, be sure it is not authenticating with NTLM.

To ensure that TELNET is not authenticating with NTLM:

  1. On the Windows server from a DOS prompt (as administrator), enter the tlntadmn command to view the current settings.
  2. Review the output.
  3. The setting Authentication Mechanism : NTLM, Password indicates authentication using NTLM.
  4. If the Authentication Mechanism lists NTLM, enter the following command to remove NTLM as an authentication mechanism: tlntadmn config sec=-NTLM
  5. If the configuration mode is Console, enter the following command to change the configuration mode from console to stream: tlntadmn config mode=stream
  6. To have these changes take effect, restart TELNET by clicking the Windows Start button and then clicking: Programs > Administrative Tools > Services
  7. In the Windows Services GUI in the Name column, select Telnet and then click the restart link.

Known issues

The following items are known issues in the current release. For issues that are being tracked on the F5 internal database, note the tracking numbers that appear in parentheses.

Local discovery of Windows servers may fail if the Local Discovery script is not same version as Data Manager (34905)

To guarantee a successful local discovery:

  1. Download the Local Discovery script from the Documentation page of the currently-running version of Data Manager.
  2. Execute the local discovery or rediscovery as appropriate. (File Servers > File Server Summary > Add/Rediscover).

File System Inventory:The task of inventorying a Windows 2003 share from Data Manager (installed on a Windows 2003 server) fails, but succeeds after reboot (34173)

You encounter this connection error on a Windows 2000 server when trying to inventory a remote system due to problems with an unknown username or password (as indicated in the inventory log). Repeated attempts result in failure with the same error message, even though you specify the correct credentials. Should you encounter this connection error, check for the following problems which can cause problems connecting to a remote share:

  • Persistent network connection with an invalid password.
  • Service using a user account with an invalid password.
  • Trust relationship has been broken.
  • Network error reaching domain controller. (Can you reach anything else in the same domain?)
  • DNS server connection issue.
  • Permissions have changed on the share.
  • Date skew on the local machine. (Possibly the password has expired.)

Workaround: Rebooting clears this issue. For more information, see the Microsoft article, Troubleshooting Unwanted "Access Denied" Messages in Domain-Based Networks (Windows NT 3.x and 4.0).

Installer: During installation of Data Manager on Windows 2000, a dialog pops up stating "LogonUser (1314): a required privilege is not held by the client" (34661)

Installing on Windows 2000 requires the privilege of "acting as part of the operating system." This issue does not occur on later versions of Windows operating systems.

Workaround: Temporarily grant an administrator the privilege of "acting as part of the operating system" using the following procedure.

  1. From the Start button, click Programs > Administrative Tools > Local Security Policy.
  2. In the navigation pane, click Local Policies.
  3. In the content pane, double-click User Rights Assignment.
  4. Right-click Act as part of the operating system.
  5. Select Security. The Local Security Policy dialog for "Act as part of the operation system" is displayed.
  6. Click Add.
  7. Change the Look in dropdown so that it shows the area (local host or domain) from which you'll be adding users/groups.
  8. Select Administrator and/or Administrators from the list of users and groups.
  9. Click Add.
  10. In the Add dialog, click OK.
  11. In the Local Security Policy dialog, click OK.
  12. Right-click Act as part of the operating system.
  13. Select Security The Local Security Policy dialog for "Act as part of the operation system" is displayed.
  14. Verify that the local policy setting check boxes and the effective policy check boxes are both checked for the new users and groups that you've added.
  15. Log out and log back in to make changes to the "Effective settings" of the "Act as part of the the operating system" policy effective.

Long multibyte character report name wraps on front page of report, causing the front page to increase to two pages (34755)

When generating batch Summary reports, enter short names for the report because the inventory name gets appended to the report name and if the report name is too long, it will wrap to a second line, causing the front page to increase to two pages. This issue occurs only for batch Summary reports. In the Reports wizard, the user is constrained to a maximum number of characters allowed in the report name field (UI) to 40. Both single byte and multibyte characters fit in one line.

Report Summary: Cannot open report with multibyte character filename (34779)

If you use more than 28 multibyte characters to name a report file, you can encounter problems when trying to open that file through the link on the Report Summary page when using Firefox or any Mozilla-based browser. No issues have been seen when using IE 7.

Workaround: Open the file outside the browser. The file is located in the Reports directory. You can view the path to the Reports directory on the File System Inventory Module Settings page.

NFS ACL warnings appear in the discovery log as "not supported." (30927)

ACL warnings appear in the discovery log as "not supported." The customer receives these warnings even though the storage can be mounted and accessed from an ARX.

For most of the NFS ACL option warnings there is a general explanation. Many of these flagged options are associated with changing the filer's behavior on a per client basis and are not associated with client authorization and access. These behavioral options are not implemented on the ARX and therefore will not be enforced by the ARX. Secondly, since the ARX is acting as a proxy between the file server and the client machine, the file server cannot distinguish between different client machines.

For example, suppose there are 2 different clients for an NFS export, 1 client has an option and the other does not. The ARX as a proxy does not distinguish between those clients and appears to the filer as a single client. So, both clients will get the same option setting.

Compressed files may cause capacity inventoried to appear greater than total/used space. (32378)

If you have compressed files (CIFS only) and then inventory the file system containing the compressed files, you may see the reported total capacity inventoried as greater than both the used space and total space of the file system. This occurs because Data Manager defines capacity inventoried as the total uncompressed size of all files inventoried. You can see capacity inventoried in the Capacity tab:

Statistics Files > File System Statistics File Details > Capacity tab > Total Disk Capacity

File System Inventory Wizard: Section selection does not work for summary report in RTF format. (32576)

If you generate a summary report and choose the Customize option on the first page of the Inventory wizard and then select only the first sections for inclusion in the report (General Information, Files And Directory Information, Capacity, CIFS Information) and, finally, select RTF for the report format, the result is a complete summary report including ALL sections and not just the selected sections.

If you upgrade your trialware version and time has not expired, save your database. (33839)

If you upgrade your trialware version and time has not expired on the initial trialware version, you must save your database or you will invalidate the remainder of your trial period.

Windows SSH file server discovery does not time out. (29570)

If you have tried to cancel a file server discovery and the operation does not terminate after 60 seconds, stop and then restart the FFNM service using the application links under the Microsoft Windows(TM) Start menu.

Corrupt ffnm.zip is created when memory usage of the Web application is high. (30735)

If you attempt to collect diagnostics and the ffnm.zip file is corrupted, it may be because memory usage on the Data Manager server is high (more than 260 M). Restart Data Manager and you should be able to collect diagnostics successfully.

File System Inventory Report:Owner appeared as "Everyone" for NFS shares inventoried over Windows SFU (33758)

Prior releases of Data Manager may have had the appearance of collecting owner and link information for NFS shares inventoried over Windows Services for UNIX (SFU). The owner would appear as S-1-1-0, which equates to "Everyone." This data is not collected as SFU is not capable of delivering it to Data Manager.

Discover and configuration: DM does not handle an EMC share explicitly assigned to multiple cifs servers (31366)

Data Manager misses a CIFS server assignment on a share when the share is configured in the GUI for multiple CIFS severs.

Script that grants proxy user share level access overwrites existing permissions (rmtshare issue) (32280)

If you follow our current workflow (non-subshare case), we create new hidden shares and then copy existing permissions from the original shares to the new shares. We then run a separate script to grant the proxy user access to the shares.

In testing against a NetApp file server, it appears that rmtshare will overwrite any existing share permissions, and you are left with only the proxy user having access.

Windows Discovery: Active Directory (AD) domain is not discovered properly when DNS domain is different. (30150)

The discovery commands assume that the DNS and AD domains are the same. This is a known issue.

Discovery: RPC-based discovery is not compatible with Simple File Sharing (33945)

RPC-based discovery does not succeed on a Windows system that has Simple File Sharing enabled. When Simple File Sharing is enabled, remote users authenticate as Guest and Guest accounts do not have administrative rights which are required to execute a successful remote discovery.

Can't inventory an NFS export called "/" (32916)

This is a Windows Services for UNIX (SFU) limitation. SFU doesn't support inventorying "/".

File System Inventory: When inventorying NFS exports on Linux kernel 2.6.9, you may encounter skipped directories (32430)

When running an inventory over an SFU mount point that is located on a Redhat Enterprise 4 (or any Linux using kernel 2.6.9), you may encounter an error in the logs:

Import: Internal directory error encountered. Skipping directory tree

The directory path is included in the error message. This error is caused by variable length file handles used by the kernel, which Microsoft's SFU is unable to process correctly. The inventory proceeds normally from that point, but the results will miss the directory in question.

Windows 2003 R2 NFS client (32397)

If using Windows 2003 R2 NFS Client for Windows (NFSClient) for NFS inventory, you may receive the following error messages:

  • Network Error 53
  • The data area passed to a system call is too small
  • Unknown Error

The NFS client included with Windows Server 2003 R2 (NFSClient) can return a variety of errors when trying to access NFS exports on UNIX-based NFS servers. The exact wording of the error message may vary depending on your environment. You might get one or more like the ones mentioned above. It is also possible that SFU 3.5 Client for NFS may work fine.

If you analyze the network traffic, you may see MOUNT commands or NFS calls being "rejected for security reasons (5)."

NFSClient uses high ports (>1024) to connect to NFS servers and that's known to cause errors such as those listed above. Use one of the following methods to fix the problem:

  • Change how your NFS servers export the NFS shares and enable them to accept connections from high ports.
  • Add UseReservedPorts DWORD value under HKLM\Software\Microsoft\Client for NFS\CurrentVersion\Default and set it to 1.

Restart NFSClient to allow the change to take effect.

Hard links are not reported for the Windows shares (30730)

The user can create hard links on Windows and they behave as they do in UNIX, but the Report function does not recognize them. This appears to be an OS/network problem. According to Microsoft, referring to the call made by Data Manager: "Depending on the underlying network components of the operating system and the type of server connected to, the function may fail, return partial information, or full information for the given file."

Mapped drives on Data Manager server cannot be (locally) inventoried (30526)

When attempting to inventory a non-C: local drive from the Data manager GUI, SAT reports that the path is not found. Data Manager cannot inventory (locally) mapped drives.
