Using the Storage Partitioning Wizard

You define by assigning a . This mapping grants a or a access to a particular or to a number of logical drives in a .

You use the Storage Partitioning Wizard to define a single storage partition. The wizard guides you through the major steps required to specify which host groups, hosts, logical drives, and associated are to be included in the storage partition.

Storage partitioning fails under these conditions:

Storage partitioning is unavailable under these conditions:


Note:

You can include a in a storage partition. However, any hosts that are mapped to the secondary logical drive will have read-only access until the logical drive is promoted to a , or the is removed.

If a has not been defined and the Storage Partitioning premium feature has been enabled, an informational dialog appears each time you select the Mappings tab. You must define the storage partitioning topology before you define the actual storage partition:

  1. Did you previously define a storage partitioning topology?
  2. Do you have two or more hosts that will share access to the same logical drives?
  3. Define the host group. For more information, refer to the Defining a Host Group online help topic.
  4. Define the hosts that will access logical drives on the storage subsystem. For more information, refer to the Defining a Host online help topic.
  5. Define the HBA host ports that let a host to access logical drives on the storage subsystem. For more information, refer to the Defining an HBA Host Port online help topic.
  6. Define the storage partition by using the Storage Partitioning Wizard. In the Topology pane of the Mappings tab, select any node or object, and select Mappings >> Define >> Storage Partitioning .
  7. Follow the directions on each of the dialogs, and click Next when you are ready to move to the next dialog.


    Note:

    You can also define storage partitions by using the Define Additional Mapping dialog.

    You will encounter these dialogs when you use the Storage Partitioning Wizard:

    • The Storage Partitioning Wizard - Introduction dialog describes the process of creating a storage partition. The dialog reminds you that you must create the required logical drives and host groups, hosts, or both before continuing.
    • The Storage Partitioning Wizard - Select Host Group or Host dialog lets you select a single host group or host for which access is to be defined.
    • The Storage Partitioning Wizard - Select Logical Drives/LUNs dialog guides you through the process of selecting a logical drive, and assigning a LUN that the host group or host will use to access the logical drive. The wizard is completed on this dialog.
