How to Move a Host

1

From the Storage Partitioning Definitions Window, select a host from the Topology View; then, select either the Configure >> Topology >> Move Host pull-down menu option, or Move Host from the right-mouse pop-up menu.

Result: The Move Host dialog is displayed. The Host name is listed on the dialog.

Example: You desire to move the host Omaha A from host group Omaha to host group Kansas City. You selected the host Omaha A under the host group Omaha.

2

Select the desired host group from the Host Group name: drop-down list. The drop-down list displays a choice of "None", followed by an alphabetical list of all host groups.

Important: The "None" choice is appropriate when you want to remove a host from any defined host group.

Example: You select the host group Kansas City.

3

Select OK.

Result: The changed host-to-host group definition is saved and the dialog closes. There are several result variations:

If you selected

Then

A different host group

The host and its associated host ports are removed from the previous host group and are now displayed under the chosen host group. The host and its associated host ports inherit the new host group's logical drive-to-LUN mappings. If the host also had any of its own specific mappings, these are retained.

In our example, Omaha A is removed from the Omaha host group and is now displayed under the Kansas City host group.

Condition 1: If the host was the only host under the previous host group, the host group loses its association to the host but retains the host group's current logical drive-to-LUN mappings. However, these logical drive-to-LUN mappings will be inaccessible until you re-define associated host(s) and host port(s) for this host group.

Condition 2: If the host was the only host under the previous host group and the host group does not have any logical drive-to-LUN mappings, the host group is moved back under the Default Host Group and inherits any default logical drive-to-LUN mappings.

None

Condition 1: If the host does not have any of its own specific logical drive-to-LUN mappings and only has the mappings associated with the host group, the host (and its associated host ports) are returned to the Default Host Group and inherit any default mappings.

Condition 2: If the host has its own specific logical drive-to-LUN mappings in addition to the mappings associated with the host group, the host (and its associated host ports) are moved under the Storage Subsystem indicating that the host still has its own specific logical drive-to-LUN mappings but it is no longer associated with a host group.
