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
■
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.
