Removing private mappings from a host
A host can access only those volumes on your Storwize V7000 system that are mapped to it. 
If we want to remove access to all volumes for one host, regardless of how many volumes are 
mapped to it, complete the following steps: 
1. From the Hosts pane, select the host, click Actions → Remove Private Mappings to 
remove all access that the selected host has to its volumes (see Figure 8-32).

Note: The SCSI ID of the volume can be changed only before it is mapped to a host. 
Changing it after is not possible unless the volume is unmapped from it again.
