Procedure

1

From the Mappings View window select a host group, host, or host port from the Topology View, or a single logical drive from the Defined Mappings View, then do one of the following:

  • Select the Mappings >> Delete pull-down menu option.
  • Select Delete from the right-mouse pop-up menu.
  • Press the Delete key.

Result: A confirmation dialog is displayed.

2

Select Yes to delete the node or the logical drive-to-LUN mapping and close the Delete confirmation dialog.

Result:

If you selected a...

Host Group, Host, or Host Port under the Default Group Node...

Host Group

The host group and its associated hosts and host ports are removed from the Topology View.

Any default logical drive-to-LUN mappings associated with the Default Group are unaffected and remain in the Topology View.

Any host ports that were associated with the host group become undefined. For information on how to view the undefined host ports, see Showing All Host Port Information.

Host

The host and its associated host ports are removed from the Topology View.

Any default logical drive-to-LUN mappings associated with the Default Group are unaffected and remain in the Topology View. Also, if the host is part of a host group, the host group is unaffected.

Any host ports that were associated with the host become undefined. For information on how to view the undefined host ports, see Showing All Host Port Information.

Host port associated with a host group or a host

The host port is removed from the Topology View and is no longer associated with a host group or host. However, any host group or host associated with the host port is unaffected.

Any default logical drive-to-LUN mapping associated with the Default Group are unaffected.

For information on how to view the undefined host ports, see Showing All Host Port Information.

Host Group, Host, or Host Port that has Specific Logical Drive-to-LUN Mappings...

Host Group

The host group and its associated hosts and host ports are removed from the Topology View.

Any specific logical drive-to-LUN mappings are deleted from the Defined Mappings View and the associated logical drives are available for a new mapping using the Define New Mapping option.

Any host ports that were associated with the host group become undefined. For information on how to view the undefined host ports, see Showing All Host Port Information.

Host

The host and its associated host ports are removed from the Topology View.

Any specific logical drive-to-LUN mappings are deleted from the Defined Mappings View and the associated logical drives are available for a new mapping using the Define New Mapping option.

If the host is part of a host group that has its own specific logical drive-to-LUN mappings, the host group is unaffected. However, if the host is part of a host group that does not have any other mappings, the host group and any other associated hosts/host ports will be moved back to the Default Group and inherit any default mappings.

Any host ports that were associated with the host become undefined. For information on how to view the undefined host ports, see Showing All Host Port Information.

Host Port

The host port is removed from the Topology View and is no longer associated with a host group or host. However, any host group or host associated with the host port is unaffected.

Any specific logical drive-to-LUN mappings associated with the host group or host are unaffected. However, if this was the last host port, these logical drive-to-LUN mappings will be inaccessible until you redefine associated hosts and host ports.

For information on how to view the undefined host ports, see Showing All Host Ports Information.

A Logical Drive-To-LUN Mapping in the Defined Mappings View...

The only logical drive-to-LUN mapping or the last logical drive-to-LUN mapping associated with a host group or a host

The logical drive-to-LUN mapping is removed from the Defined Mappings View. The associated logical drive is available for a new mapping using the Define New Mapping option.

The host group and/or hosts and host ports associated with the mapping are moved back under the Default Group in the Topology View and inherit any default mappings.

If this mapping is associated with a host group and one or more of its hosts has specific mappings, the deletion will not be allowed until you move or delete the specific mappings of the hosts.

One of many logical drives associated with a host group or a host

The logical drive-to-LUN mapping is removed from the Topology View and is no longer associated with its respective host group or host. The associated logical drive is available for a new mapping using the Define New Mapping option.

The host group or host is unaffected.
