HP P9000 Provisioning for Mainframe Systems User Guide (AV400-96369, October 2011)

2 Configuring resource groups
The Storage Administrator can divide a provisioned storage system into resource groups that allow
managing 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.
Resource groups can be set up on both open and mainframe systems. Resource Partition software
is required.
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
• External volumes (VDEVs)
• Ports
Resource groups should be planned and created before creating volumes. Before creating LDEVs
or host groups, an LDEV ID or a host group ID can be assigned to the resource group in advance.
The following tasks provide instructions for configuring resource groups.
• “Creating a resource group” (page 17)
• “Adding resources to a resource group” (page 17)
• “Removing resources from a resource group” (page 18)
• “Changing the name of a resource group” (page 18)
• “Deleting a resource group” (page 19)
Meta_resource
The meta_resource is a resource group in which additional resources (other than external volumes)
and the resources existing on your storage system before installing Resource Partition belong.
When a storage system is upgraded to include Resource Partition, existing resources initially belong
to meta_resource by default to ensure compatibility with older software.
Resource lock
While processing a task on a resource, all of the resource groups assigned to the logged-on user
are locked for exclusive access.
A secondary window (such as the Basic Information Display) or an operation from the service
processor (SVP) locks all of the resource groups in the storage system.
When a resource is locked, a status indicator appears on the Remote Web Console status bar.
Click the Resource Locked button to view information about the locked resource.
