Dynamic LUN or Volume Reassignment

You can use this feature to re-assign the LUN/volume either from one server to another or within the same server.

  1. Make sure that you have formatted and created a file system or assigned a drive letter to the device on the server that you want to re-assign.
  2. If the storage resource is not formatted for use by the operating system, the resource cannot be dynamically reassigned and mounted or assigned a drive letter for use by the application automatically.

    In the Resource Allocation view, each tree node is listed with a descriptive tag. The following descriptions can help you decipher the tree view.

    Tag Description
    <Vendor><Product ID><SN#> <Vendor>=vendor name, <Product ID>=product name and
    <SN#>=serial number of RAID controller, such as Dot Hill SANnet II SN#3062615
    <IP Address> <Server Name> IP address and name of the server such as 206.6.18.23 Hurricane
    Servers
    <IP Address> <Server Name> <OS Platform>
    IP address, name and OS platform of the server, such as 206.6.18.23 Hurricane WIndows 2000 Build 1381

  3. Before continuing, verify that no application is using this storage resource.
  4. Click New MP/DL in the drop down list box and specify the new mount point or the driver letter under which you want this resource to be reassigned on the server. Make sure you press Enter after the new mount point or driver letter is entered to enable Apply.
  5. Click Apply, and then close the view.
  6. Now the resource is available on the server under the new mount point or drive letter specified. Any application can access this resource for use.

    NOTE: If you have made use of this dynamic LUN assignment feature, the table of file system defaults such as /etc/vfstab might have been modified to ensure the availability of the resource across array system reboots.
