Create LUN: Define Mapping by LUN Number

Mapping a LUN makes the LUN available to the host. You can specify that the LUN map to a specific LUN number that any SAN host entry can use.

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 All hosts may access the LUN using LUN number.
6. Select a LUN number from the drop-down list to assign to the LUN.
   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.
7. 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>.
8. (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.
9. Click OK.
