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
Ports
NOTE: Before you create LDEVs, the LDEV IDs can be reserved and assigned to a resource group
for future use.
The following tasks provide instructions for configuring resource groups.
"Creating resource groups" (page 24)
"Editing resource groups" (page 25)
"Deleting resource groups" (page 26)

Resource groups examples

The following examples illustrate how you can configure resource groups on your storage system.
"Example of resource groups sharing a port" (page 20)
"Example of resource groups not sharing ports" (page 22)

Example of resource groups sharing a port

If you have a limited number of ports, you can still operate a storage system effectively by sharing
ports using resource groups.
The following example shows the system configuration of an in-house division providing virtual
private storage system for two divisions. Divisions A and B each use their own assigned parity
group, but share a port between the two divisions. The shared port is managed by the system
division.
