Setup

  • After you have completed all of the installation steps, continue to set up your system by performing the post-installation tasks.
  • Connect a management station.

  • You must connect a management station to your system directly or remotely over a sub network.

  • This computer will be used to continue setting up your system and must be on the same subnet as the storage system to complete the initialization.

  • Downloading the Unisphere Storage System Initialization Wizard. 

  • Go to htpps://support.emc.com and select VNX series > Install and Configure.

  • From VNX installation tools, download the Unisphere Storage System Initialization Wizard.

  • Double click the downloaded executable and follow the steps in the wizard to install the utility.

  • On the install complete screen, make sure that the Launch Unisphere Storage System Initialization Wizard check box is selected, click done.

  • The initialization utility opens. Follow the online instructions to discover and assign IP address to your storage system.

  • Check system health.

  • Login to Unisphere to check the health of your system, including alerts, events and statistics.

  • Open a browser and enter the IP address of SP.

  • Use the sysadmin credentials to log in to Unisphere. You may be prompted by certificate-related warnings. Accept all the certificates as “Always trust”.


  • Select your storage system and select System > Monitoring and alerts. 


Set the storage system cache values

  • You must allocate cache on the system. Allocate 10 % of the available cache (with a minimum of 100 MB and a maximum of 1024 MB) to read and the rest to write. 

  • Open a browser and enter the IP address of SP.

  • Use the sysadmin credentials to log in to Unisphere. You may be prompted by certificate-related warnings. Accept all the certificates as “Always trust”.

  • Select your storage system and select System > Hardware > Storage Hardware.

  • From the task list, under system management, select manage cache.


Install ESRS and configure ConnectHome

  • You can ensure that your system communicates with your service provider by installing the VNX ESRS IP Client.

  • Select the appropriate options for your configuration.

  • Select install and configure ESRS to generate a customized version of EMC Secure Remote Support IP Client.

CONFIGURE SERVERS FOR VNX SYSTEM

  • Installing HBAs in the server.

  • For the server to communicate with the system Fibre Channel data ports, it must have one or more supported HBAs installed.

  • If the server is powered up:

 a. Shut down the server's operating system.

 b. Power down the server.

 c. Unplug the server's power cord from the power outlet.

Put on an ESD wristband, and clip its lead to bare metal on the server's chassis.

For each HBA that you are installing:

 a. Locate an empty PCI bus slot or a slot in the server that is preferred for PCI cards.

b. Install the HBA following the instructions provided by the HBA vendor.

c. If you installed a replacement HBA, reconnect the cables that you removed in the exact same way as they were connected to the original HBA.

Plug the server's power cord into the power outlet, and power up the server.


Installing or updating the HBA driver

The server must run a supported operating system and a supported HBA driver. EMC recommends that you install the latest supported version of the driver.

If you have an Emulex driver, download the latest supported version and instructions.

For installing the driver from the vendor’s website.

http://www.emulex.com/products/fibre-channel-hbas.html

If you have a QLogic driver, download the latest supported version and instructions.

For installing the driver from the vendor’s website.

http://support.qlogic.com/support/oem_emc.asp


Installing the HBA driver

Install any updates, such as hot fixes or service packs, to the server’s operating system  that are required for the HBA driver version you are installing.

If the hot fix or patch requires it, reboot the server.

Install the driver following the instructions on the HBA vendor’s website.

Reboot the server when the installation program prompts you to do so. If the installation program did not prompt you to reboot, then reboot the server when the driver installation is complete.

Installing the Unisphere Host Agent on a windows server

Log in as the administrator or a user who has administrative privileges.

If your server is behind a firewall, open TCP/IP port 6389. This port is used by the host agent. If this port is not opened, the host agent will not function properly.

If you are running a version prior to 6.26 of the host agent, you must remove it before continuing with the installation.

Download the software

From the EMC Online Support website, select the appropriate VNX Series Support by Product page and select Downloads.

Select the Unisphere Host Agent, and then select the option to save the software to your server.

Double-click the executable file listed below to start the installation wizard.

Unisphere Host Agent-Win-32-x86-en_US-version-build.exe.

Follow the instructions on the installation screens to install the Unisphere Host Agent.

The Unisphere Host Agent software is installed on the Windows server. If you selected the default destination folder, the software is installed in the C:\ProgramFiles\EMC\HostAgent.

Once the Unisphere Host Agent installation is complete, the Initialize Privileged User List dialog box is displayed.

In the Initialize Privileged User List dialog box, perform one of the following:

If the Config File field contains a file entry, then a host agent configuration files already exists on the server from a previous agent installation. Select Use Existing file to use this configuration file or select Browse to use a different file.

The host agent configuration file contains a list of login names for this server. Only users whose usernames are listed in the Privileged User List can send CLI commands to the system.

To add a user to the list:

Click Add to open the Add Privileged User dialog box.
In the Add Privileged User dialog box, under User Name, enter the person’s account username, for example, Administrator.

Under System Name, enter the name of the host running Unisphere > (for example, Host4) and click OK.

To remove a privileged user from the list:

a. Select the privileged username, and click Remove

Click OK to save the new privileged user list and /or >the new configuration file.

The program saves the host agent configuration file with the new privileged user entries and starts the host agent.

Click Finish.

A command line window opens indicating that the host agent service is starting.

If the system prompts you to reboot the server, click yes.

Connecting the VNX to the server in a Fibre Channel switch configuration

Use optical cables to connect switch ports to the VNX Fibre Channel host ports and to Fibre Channel switch ports and to connect the switch ports to the server HBA ports.

For highest availability in a multiple-HBA server, connect one or more HBA ports to ports on the switch and connect the same number of HBA ports to ports on same switch or on another switch, if two switches are available.


High-Availability-(HA)-of-servers

Zoning the switches

We recommend single-initiator zoning as a best practice. In single-initiator zoning each HBA port has a separate zone that contains it and the SP ports with which it communicates.
