Viewing or Deleting LUN Mappings | Compaq Infortrend manual

7.10Viewing and Editing Host LUNs

Viewing or Deleting LUN Mappings

Choose the host channel and host ID combination you wish to view or delete.

A list of the current LUN mapping will be displayed on the screen. Move the cursor bar to the LUN mapping you wish to delete, then press [ENTER]. Select Yes to delete the LUN mapping, or No to cancel.

Edit Host-ID/WWN Name List

This is a specific item used for systems communicating over Fibre host loops. Please refer to Chapter 8 Fibre Operation for more details.

Pass-through SCSI Commands

If you have primary and secondary controllers, move the cursor to the controller for the device that you wish to map; then press [ENTER]. You will be prompted to map a SCSI ID to a physical drive.
