• External volumes
• Ports
• Host group IDs
• iSCSI target IDs
Note:
Before you create LDEVs, you can reserve the desired number of LDEV
IDs and assign them to a resource group for future use. You can also reserve
and assign host group IDs and iSCSI target IDs in advance because the
number of host groups or iSCSI targets per port is limited.
meta_resource
The meta_resource group is the resource group consisting of the resources
that exist on the storage system (other than external volumes) before
Resource Partition Manager is installed. By default, all existing resources
initially belong to the meta_resource group to ensure compatibility with older
software when a system is upgraded to include Resource Partition Manager.
Resource lock
When a task is being processed on a resource, all of the resource groups
assigned to the logged-on user are locked for exclusive access. When a
resource is locked, a status indicator appears on the Device Manager -
Storage Navigator status bar. To view information about the locked resource,
click Resource Locked.
Note:
Opening a Device Manager - Storage Navigator secondary window
(such as
Basic Information Display
) or performing an operation from the
service processor (SVP) locks all of the resource groups in the storage
system.
Resource group examples
The following examples illustrate how you can configure resource groups on
your storage system.
•
Example of resource groups sharing a port on page 168

Example of resource groups not sharing ports on page 170
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.
