3 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
•
Host group IDs*
* Before you create LDEVs, the LDEV IDs can be reserved and assigned to a resource group for
future use. Host group numbers can also be reserved and assigned in advance because the number
of host groups created on a single port is limited.
The following tasks provide instructions for configuring resource groups.
•
“Creating a resource group” (page 31)
•
“Adding resources to a resource group” (page 32)
•
“Removing resources from a resource group” (page 33)
•
“Changing the name of a resource group” (page 33)
•
“Deleting a resource group” (page 34)
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 27)
•
“Example of resource groups not sharing ports” (page 29)
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.
