If there are volumes that have not been attached to Fibre or iSCSI servers, you can use this procedure to attach them.

  • Enable security on ports.
  • Add servers.
  • Create volumes.
  1. To select volumes and servers, do one of the following:
    • On the Volumes inventory window for a storage system, select one or more volumes and click Attach Volumes to select servers on the Attach Volumes window.
    • On the Servers inventory window, select one or more servers, then click Attach Volumes to select volumes on the Attach Volumes window.
    • On the detail window for a pool, select one or more volumes, then click Attach Volumes to select servers on the Attach Volumes window.

  2. Click Next to view options for attaching existing volumes.

  3. The Host Mode is set by default to the server operating system. You can make a selection if needed.
    The server OS Type is provided when the server is added to Ops Center Administrator.
  4. The prepopulated Host Mode Option depends on the Host Mode selection. The default Host Mode Option can be changed manually.
    Ops Center Administrator identifies all host groups containing any of the server WWNs. If all of those host groups have the same host mode and host mode options, those settings are prepopulated with the same settings in the host groups.
    Default values are set only for VMWARE EX and WIN EX host modes. The default for all other Host Modes is none.
  5. Select Mandate LUN Alignment.
    This option specifies whether to assign the same LUN number to multiple servers for a volume. If Yes is specified, the same LUN number is always assigned. If No is specified, the same value is not necessarily used. If the attachment is to only one server, this setting has no effect.
  6. (Optional) Select a method and specify a virtual volume ID range in the Virtual ID/Range field.
  7. The Auto Create Zone is set to No by default. You can set it to Yes to automatically create zones.
  8. (Optional) Enter the LUN number to which you want to attach the volume.
  9. Click Next to view options for creating and editing LUN paths.

  10. In the Create Paths window, you can view servers and their WWNs, along with ports on the storage system. The following options are available for managing LUN paths:
    For VSP 5000 series storage systems, you can click a port to display a list of ports with their DKC locations, CTL locations, and redundancy levels.
    Port redundancy level

    Ops Center Administrator will scan for existing host groups on the storage array and try to reuse them by default. The following options are available for managing LUN paths:
    • If you connect more than one server to the same port, the Share a host group with all servers box displays. Select the box to add the servers to a single host group.
      Note: If host groups already exists on that port and single host group cannot be created, the check box will not appear.
    • Existing paths are populated as follows: all existing host groups with one or more server WWN and the exact same host mode and host mode options selected on the Attach Settings window are populated as paths.
    • To prevent the volume from being added to an existing path, click the existing path to remove it.
    • Click Suggest to populate automatically selected paths. By default, the least-used ports are selected.
    • To manually create a path, click WWNs to select them and click a port to connect them with blue connector lines. To delete the connection, click the connector again. Suggest paths need for both server and storage ports to be logged into the fabric switches in the Ops Center Administrator inventory.
    • Optionally, you can click Switch View to use tables to create paths by selecting Server Ports to attach to Storage Ports.
  11. Click Next to continue to the optional Operation Plan step, you can confirm settings specified in each window and can confirm the resources to be used in the job, including LUN candidates.
    Note:

    To view the plan summary page, limit the number of LUN Paths to 5000.

  12. You can specify the LUN range for volumes in the LUN Settings pop up window which is launched by clicking LUN Settings button above the Planned Path Configuration table.
  13. You can make it mandatory to use the LUNs displayed in the table by specifying Yes to Mandate Using Displayed LUN.
  14. When you are satisfied with all the settings, click Submit.
