Remove Mappings from a Server

You can either select a volume and remove the mapping to the server, or select a server

and remove volumes mapped to it. This command is similar for servers, server clusters, or

virtual servers.

 To remove mappings from a server

1 In the system tree, select a server.

2 From the shortcut menu, select Remove Mappings from a Server. The system

displays volumes mapped to that server.

3 Select mappings to remove.

• Make sure that the volume mapped to this server is no longer mounted; if you

remove an active map entry, the server using the volume will have read/write errors.

The system warns you if you are attempting to remove an active map entry.

• Make sure that removing this mapping will not create a gap in the LUN sequence.

Most operating systems require contiguous LUN sequencing starting with LUN 0. A

gap in the LUN sequence may cause the server to fail to recognize subsequent

volumes.

4 Click Remove Now. The mapping is removed.
