Modifying open systems volume groups

Complete this task to modify open systems volume group properties and parameters.

1. In the navigation, select Real-time manager or Simulated manager > Configure storage > Open systems > Volume groups. On the Volume groups main page, in the Select storage unit drop-down list, select the storage unit that contains the volume group that you want to modify.
2. Select the volume group that you want to modify. In the Select Action drop-down list, select Modify..., and then click Go. The Modify Volume Group — Define volume group properties page is displayed.
3. Accept or modify the properties according to the following conditions: If you modify the host types that can access this volume group, then the host attachments in the Selected host attachments page might also require modification. You must make changes that are compatible with the current definition of the volume group. For example, you cannot add host types with differing block size and addressing methods, and you cannot remove all the host types from the selection. Valid modifications include adding other host types that are compatible with the current volume group definition and removing host types (as long as at least one remains).
4. Click Next to continue. The Modify Volume Group — Select host attachments page is displayed.
5. Accept or modify values. You can specify a different nickname from this page. If you change the host attachment, then the Selected volumes might also require modification. If you changed from a particular host type to another, namely from AS/400 to any other open systems host (or vise versa), then the subsequent pages require modification. Finish will be disabled until the user makes all the required changes.
6. Click Next to continue. The Modify Volume Group – Select volumes for groups page is displayed.
7. Accept or modify the volumes for the volume group. Select the volumes that you want to use in this volume group. You can use the Create new volumes button to create a new volume. After you create the volume and the table resets, the new volume is available for selection.
   Tip: If you created volumes with the same nickname prefix, you can change the view to show only those volumes that you want to select either by sorting the nickname column or by creating a filter.
8. Click Next to continue. The Modify Volume Group — Verification page is displayed.
9. Use the Verification page to review the attributes and verify that they are correct.
10. If the attributes and values are not correct, click Back as appropriate to return and then specify the correct values. Otherwise, click Finish to complete the volume group modification process.
