2 About Volume Security Operations Overview of Volume Security Functions The Volume Security feature protects data in your storage system from I/O operations performed at mainframe hosts. Volume Security enables you to apply security to volumes so that the specified mainframe hosts will be unable to read from and write to the specified volumes. Volume Security also enables you to prevent data on volumes from being overwritten by erroneous copy operations. Volume Security can be used in conjuncti

• The volume ldev4 is accessible only from host4 because ldev4 and host4 are registered in the same access group. • The volume ldev5 does not belong to any access groups. For this reason, hosts in access groups cannot access ldev5. ldev5 is only accessible from host5 and host6, which are not registered in access groups. Figure 1 Security Example 1 Port-Level Security Usually, hosts are connected to two or more ports via cables and have access to volumes via these ports. In the security example i

Figure 2 Security Example 2 If no ports are registered in a host group, hosts in the host group can access volumes via ports to which the hosts are connected. This manual uses the term port-level security, which is a security policy for enabling hosts to access volumes only via ports registered in host groups and thus prohibiting hosts to access the volumes via other ports. CAUTION: Before you apply security, you should confirm what hosts are performing I/O operations on volumes in access groups

volumes (vol_A and vol_B) in a pool group, all the mainframe hosts connected to your storage system will be unable to access vol_A and vol_B. To register volumes in a pool group, you must create an LDEV group, register the volumes in the LDEV group, and then register the LDEV group in the desired pool group. Any pool group can only contain one LDEV group. In Figure 3, a pool group is created. Volumes in this pool group (that is, ldev7, ldev8, and ldev9) are inaccessible from all the hosts: Figur

When applying security, make sure that your security settings are correct. If incorrect security settings are made, the system will be difficult or impossible to control. If the CPU of a mainframe host is upgraded after you apply security settings, you must execute the system command D M=CPU at the mainframe host to obtain the latest information about the host. Next, you must use the latest information to update host information in the Add/Change Host dialog box (for details, see “The Add/Change
