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.

NoteOpening 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.

  • Creating resource groups and managing storage system resources

    You can divide a provisioned storage system into resource groups that allow you to manage 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.
