Create LUN: Define Mapping by Selected Host Entries

Mapping your LUN makes the LUN available to the host entry. You can specify that your LUN map to a specific host entry and LUN number.

1. Navigate to SAN > Storage > LUNs.
2. Select Actions > Create.
3. Click the Mapping tab.
4. Select the Access Protocol that permits access to the LUN.
   Valid options:

   • Fibre Channel (FC)

   • iSCSI

5. Select the option Only selected hosts (via maps).
   Result:The system displays the Hosts mapping table.
6. From the LUN Controller Assignment controls, allow the Oracle FS System to assign the Controller, by leaving the Assigned Controller option set to the default, which is <auto assign>.
7. Click Create.
8. From the Create LUN Map dialog, define the mapping for the LUN, then click OK or click OK and Continue.
   Valid options:

   • LUN Name

   • Host Name

   • LUN Number

   Tip: If network clients are running on Windows 2000 or 2003 platforms, and you want those clients to be able to access the LUN, do not select LUN number 255.

   Note: Clicking OK and Continue allows you to map more hosts to this LUN. Clicking OK creates the LUN mapping and closes the dialog.
9. (Optional) From the Ports Masked for this LUN table, select Yes for each Controller port that you want to mask.
   When you mask a port, the LUN cannot be accessed from the specified ports.

   Note: If you use Oracle FS System LUN masking or switch zoning and do not use LUN assignment, you could create a situation in which a LUN is not exposed on the ports through which you want the clients to be able to access the LUN. To avoid this situation, assign the LUN to the Controller on which you have the mapping set.
10. Click OK.
