oWritethrough – Force all of the writes to be written to Flash before acknowledging the write as complete.
•Device ID – This is an OpenVMS specific identifier.
•Report corrected media errors to the SCSI host – This controls whether any internal corrected errors are reported over the SCSI layer to the host. By default it is enabled. For most environments this should be set.
•Report uncorrected media errors to the SCSI host – This controls whether any internal uncorrected errors are reported over the SCSI layer to the host. By default it is enabled.
After setting the appropriate values click “Next”. A final window will confirm the values. After clicking “Next” again, the Logical unit will be created. For the Logical Unit to be used, an access policy needs to be defined.
4.11.2 Adding an Access Policy to a LUN
The Web Management Interface provides the ability to create access lists for individual Fibre Channel ports. This allows the administrator to specify which worldwide port names (HBAs) are allowed to communicate with each partition. To make partitioned LUNs accessible to connected servers, the next step is to link the LUNs to the RamSan’s Fibre Channel ports. The “Logical Unit Overview” is shown in Figure 19, note that the Logical Unit is in a warning state notifying the administrator that a Logical Unit was created and has not been presented to any hosts.

Click the “Access” button on the “Logical Unit Overview” screen to start the access policy wizard. The first step of the access policy wizard will provide an overview of the process. After reading the overview, click the “Next” button to continue to the “Access Policy Table” for the Logical Unit, shown in Figure 20.
