Task 1: Configure Server Connections

Updated: February 27, 2008

Applies To: Windows Server 2008

The first task in deploying logical unit numbers (LUNs) is to configure the connections that servers in your storage area network (SAN) will use to access the LUNs that you create on your storage subsystems.

Storage Manager for SANs automatically discovers Fibre Channel ports and Internet SCSI (iSCSI) initiator adapters on a server. You only need to identify the server that will access the LUN, and then select which ports and/or initiator adapters on that server will be enabled for LUN access.

noteNote
Fibre Channel ports can also be added manually by entering their World Wide Name (WWN).

  1. In the console tree, click LUN Management.

  2. In the Actions pane, click Manage Servers Connections.

  3. To add a server:

    1. In the Manage Server Connections dialog box, click Add.

    2. In the Add Server dialog box, type the name or browse to the server that you want to add and optionally, type a description for it.

    3. Click OK. The server will now be listed in the Manage Server Connections dialog box.

  4. To configure the Fibre Channel ports on a server:

    1. In the Manage Server Connections dialog box, select a server from the server list. The Fibre Channel Ports tab lists all of the host bus adapter (HBA) ports that are available on the selected server.

    2. If you want to manually enter a new port, on the Fibre Channel Ports tab, click Add and enter the WWN of the new port. Optionally, type a description for the new port.

    3. To enable a port, select its check box in the Enable column.

      CautionCaution
      If you enable more than one Fibre Channel port and the server is not configured to use Multipath I/O, data corruption can occur. For more information about Multipath I/O, see Support for Multipath I/O earlier in this guide.

    4. After selecting all ports that you want to enable, click OK.

      noteNote
      If you create LUNs only on a Fibre Channel subsystem, no additional configuration is needed before creating LUNs. You can skip to Task 5: Create a LUN later in this guide.

  5. To configure the iSCSI initiator adapters on a server:

    1. In the Manage Server Connections dialog box, select a server from the server list. The iSCSI Initiator Adapters tab lists all the initiator adapters that are available on the selected server.

    2. To enable an initiator adapter, select its check box in the Enable column.

      CautionCaution
      If you enable more than one iSCSI initiator adapter and the server is not configured to use Multipath I/O, data corruption can occur. For more information about Multipath I/O, see Support for Multipath I/O earlier in this guide.

    3. After selecting all initiator adapters that you want to enable, click OK.
