Modify host system — Define host ports

Use this page to define host information.

Introduction

If you change anything on this page, the subsequent pages might require modification. The following list describes permissible modifications and the resulting actions:

You can add another host attachment by entering data in the following fields: Quantity , Attachment Port Type, Group ports to share a common set of volumes. Select the Add > button to add them to the Defined host ports table.
You can select an existing host port from the Defined host ports table and select the < Remove button. This action populates the related fields on the left side of the page with the information that was just removed. If you want to modify any of those fields, select the Add > button. The new host attachment is then added to the Defined host ports table. If you want to remove the it all together, proceed through the wizard.
If you remove a host attachment, the volume group that is assigned to that host attachment cannot be accessed by it. In other words, all previously defined storage unit associations (storage unit ports and volume group) with this host attachment are lost. Thus, the links are removed from the subsequent steps and you must continue through the wizard using the Next > button. The Finish button is disabled until you complete all of the required changes.
