Compaq Infortrend manual Mapping a Logical Volume to Host LUN

7.7Mapping a Logical Volume to Host LUN

Select “View and Edit Host luns” in the main menu, then press [ENTER].

A list of host channel/ID combinations appears on the screen. The diagram above shows two host channels and each is designated with both a primary and a secondary ID.

Multiple IDs on host channels are necessary for redundant controller configuration. Details on creating multiple IDs and changing channel mode will be discussed later. Choose a host ID by pressing [ENTER].

Several details are noticeable here:

1.A logical group of drives (logical drive/logical volume) previously assigned to the primary controller can not be mapped to a secondary ID. Neither can those assigned to the secondary controller mapped to a primary ID.

2.For a SCSI-based controller, ID 7 is reserved for the controller itself. If there are two controllers, controllers might occupy ID6 and ID7, or ID8 and ID9. Please check your system Hardware Manual for details on preserved IDs.

Choose the "channel-ID" combination you wish to map, then press [ENTER] to proceed. Choose mapping a “Logical Drive” or a “Logical Volume” on the drop box.
