Hitachi VSP F400, System Administration Manual, Page: 173 / 414

• A Storage Administrator with the Security Administrator (View & Modify)
role can create resource groups and assign resources to resource groups.
• Resources removed from a resource group are returned to meta_resource.
• Only a Security Administrator (View & Modify) can manage the resources
in assigned resource groups.
Restrictions
• No new resources can be added to meta_resource and
NAS_Platform_System_RSG.
• Resources cannot be deleted from meta_resource and
NAS_Platform_System_RSG.
• LDEVs with the same pool IDs or journal IDs cannot be added to multiple
resource groups.
In the case of adding LDEVs that are used as pool volumes or journal
volumes, add all the LDEVs that have the same pool IDs or journal IDs by
using a function such as sort.
Guidelines
• If you are providing a virtual private storage system to different
companies, you should not share parity groups, external volumes, or pools
if you want to limit the capacity that can be used by each user. When
parity groups, external volumes, or pools are shared between multiple
users, and if one user uses too much capacity of the shared resource, the
other users might not be able to create an LDEV.
Managing resource groups
Managing resource groups includes creating, editing, and deleting resource
groups.
Creating resource groups
When you create a resource group, you enter a name and assign the desired
resources (parity groups, LDEVs, ports, host groups, and iSCSI targets) to
the new group. You can create more than one resource group at a time.
Note the following restrictions for creating a resource group:
• The maximum number of resource groups that can be created on a
storage system is 1023. If the NAS module is installed in the storage
system, the maximum number of resource groups that can be created on
the storage system is 1022.
• A resource group name can use alphanumeric characters, spaces, and the
following symbols: ! # $ % & ' ( ) + - . = @ [ ] ^ _ ` { } ~
• The characters in a resource group name are case-sensitive.
• Duplicate occurrences of the same name are not allowed.
• You cannot use the following names:
meta_resource

NAS_Platform_System_RSG
