Creating resource groups and managing storage system resources
You can divide a provisioned storage system into resource groups that allow
you to manage the storage system as multiple virtual private storage
systems. Configuring resource groups involves creating resource groups,
moving storage system resources into the resource groups, and assigning
resource groups to user groups.
When to use resource groups
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 accidentally destroyed by a storage
administrator in another organization.
To avoid such problems, use Hitachi Resource Partition Manager software 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. Resource groups
prevent the risk of data leakage or data destruction by another storage
administrator in another resource group.
Resources such as LDEVs, parity groups, iSCSI targets, external volumes,
ports, and host groups can be assigned to a resource group. These resources
can be combined to flexibly compose a virtual private storage system. You
should plan and create resource groups before creating volumes.
System configuration using resource groups
Configuring resource groups prevents the risk of data leakage or data
destruction by another Storage Administrator in another resource group. The
Storage Administrator considers and plans which resource should be
managed by which user, and then the Security Administrator creates resource
groups and assigns each resource to the resource groups.
A resource group is assigned one or more storage system resources. The
following resources can be assigned to resource groups.
• LDEV IDs
• Parity groups
