Preparing an EMC Celerra device

You must ensure that the Celerra device is configured to support alternate data streams (ADS). Enterprise Vault uses ADS to indicate archive points. If you intend to use placeholder shortcuts on the Celerra, you must also enable the FileMover functionality on the Celerra and create an HTTP connection.

Note:

If you want to configure the pass-through behavior on placeholder recall, read about the read_policy_override parameter before you proceed.

See Configuring Celerra pass-through behavior for placeholder shortcuts.

Note:

See this technical note on the Symantec Support Web site for troubleshooting information on the following procedure:

To configure the Celerra device

  1. Log on to the Celerra Control Station.

  2. Ensure that the Celerra device is configured to support alternate data streams (ADS), which Enterprise Vault uses to indicate archive points.

    The Celerra shadow stream parameter controls support for ADS:

    • If the shadow stream parameter is set to 1, ADS support is enabled. 1 is the default value.

    • If the shadow stream parameter is set to 0, ADS is disabled.

    To determine the current value of the stream parameter, enter the following command syntax on the Celerra Network Server:

    server_param server_x -facility shadow -info stream
    

    where server_x is the name of the Data Mover.

    The command returns information about the parameter, including its current value.

    To enable ADS support, use the following command syntax on the Celerra Network Server:

    server_param server_x -facility shadow -modify stream -value 1
    

    where server_x is the name of the Data Mover.

  3. Add a Celerra account for Enterprise Vault to use for authentication on the Celerra device. The syntax is as follows:

    /nas/sbin/server_user server_x -add -md5 -passwd DataMover_user_name
    

    where:

    server_x is the name of the Data Mover

    DataMover_user_name is the name of the account that you want Enterprise Vault to use for authentication. This user is a Data Mover user, not a domain user.

    Make sure that you specify the full path for the server_user command, /nas/sbin/server_user. You require root privileges to execute this command.

  4. Enable the file system for Celerra FileMover using this command syntax:

    fs_dhsm -modify fs_name -state enabled
    

    where:

    fs_name is the name of the file system on the Celerra.

  5. Configure the HTTP server on the Data Mover to accept Celerra FileMover API connections using this command syntax:

    server_http server_x -append dhsm -users
    DataMover_user_name -hosts ip_address_policy_engine
    

    where:

    server_x is the name of the Data Mover.

    DataMover_user_name is the name of the Data Mover account that you want Enterprise Vault to use for authentication.

    ip_address_policy_engine is the IP address of the computer that runs the Enterprise Vault FSA task that will process the Celerra device.

    The command also tests the connectivity between the Celerra device and the Enterprise Vault server over http.

  6. Configure the HTTP connection to use for recall requests, using this command syntax:

    fs_dhsm -connection fs_name -create -type http
    -secondary ev_url -user user -password user_password -cgi n
    

    where:

    fs_name is the name of the Celerra file system.

    ev_url is the URL of the Enterprise Vault Web Access application. The Celerra is case-sensitive, so this URL must use the correct case. See Specifying the correct URL for the Web Access application.

    user is the Vault Service account that will have access to all the archives from which files are restored.

    user_password is the password to the Vault Service account.

    Note that you cannot include a TCP port number in the URL that you specify with the -secondary parameter. For example, if you use a non-default port such as port 85 for the Web Access application, you cannot specify the port as follows:

    -secondary http://evserver.demo.local:85/EnterpriseVault
    

    A workaround is available if you have configured the Web Access application to use a TCP port other than default port (port 80).

    See Specifying a non-default TCP port for the Web Access application.

  7. Add the Vault Service account as a member of the Administrators group of the Celerra CIFS server:

    • From Windows, click Start > All Programs > Administrative Tools > Computer Management. The Computer Management console appears.

    • Select Action > Connect to another computer. Enter the name of the CIFS server.

    • Add the Vault Service account to the Administrators group.
