Data retention strategies

After provisioning your system, you can assign access attributes to open-system volumes to protect
the volume against read, write, and copy operations and to prevent users from configuring LU
paths and command devices. Use the Data Retention to assign access attributes.

Resource groups strategies

A storage system can connect to multiple hosts and be shared by multiple divisions in a company
or by multiple companies. Many storage administrators from different organizations can access
the storage system. Managing the entire storage system can become complex and difficult. Potential
problems are that private data might be accessed by other users, or a volume in one organization
might be destroyed by mistake by a storage administrator in another organization.
To avoid such problems, use Resource Partition to set up resource groups that allow you to manage
one storage system as multiple virtual private storage systems. The storage administrator in each
resource group can access only their assigned resources and cannot access other resources.
Configuring resource groups prevents the risk of data leakage or data destruction by another
storage administrator in another resource group.
The resources such as LDEVs, parity groups, external volumes, ports, or host groups can be assigned
to a resource group. These resources can be combined to flexibly compose a virtual private storage
system.
Resource groups should be planned and created before creating volumes. For more information,
