Device mapping

This option allows the user to manipulate maps and associate selected host with a particular map. Each physical port/bus on the system has at least an Indexed map and Auto Assigned map. In addition, there is a SCC Map and a Port 0 Device Map on FCP ports. Each map has a unique name and map ID. You can rename all maps, except for Indexed, Auto Assigned, and SCC. The map that is set to be current must always contain valid information, since many of the operations on the map menu are executed against this map.

Command >

•Select 1 from the Device Mapping Main menu to display all the maps defined by the system for the current protocol/port, and to choose one of the maps from the list to make it a current map. The map selected from this list is the one used by the interface card to direct data to the appropriate targets and initiators.

NOTE: Because the entire list of maps may not fit on one screen, select N or P to go back and forth between screens displaying more maps. Select X to return to the Device Mapping Main menu.

Enter the number from the column on the left side of the table to select a map and make it Current. For example, entering 3 from the picture above would select the map named SCC Map on Fibre Channel Port 0 and make it a Current map.

•Select 2 from the Device Mapping Main menu to display the content of the current map. This option displays all the entries in the map. Information in the local part of the address (left) depends on the type of protocol for which the map is defined. The specific device address information depends on the protocol/port where the device resides. Mapping a device to the same port where it resides is not allowed. (that is, you can not map a disk on FCP Port 0 to an address on FCP Port 0.)
