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.
