A Managing virtual storage machines
This module describes specific functionality available for managing virtual storage machines.
About managing resources by using virtual storage machines
A virtual storage machine is a virtual storage system (a group of resources) that you create in an HP
XP7 Storage, and then specify virtual information for it, such as a virtual model and virtual serial
number.
There are two types of virtual storage machines within the XP7 storage system:
• Default virtual storage machine
One default virtual storage machine is created by default. The virtual information for the default
virtual storage machine uses the same values as the physical information. Initially, all resources
added to user-defined virtual storage machines are allocated from the default storage machine.
Resources of virtual storage machines are initially part of the default resource group (resource
pool).
• User-defined virtual storage machines
There is a maximum of eight virtual storage machines for a single XP7. This maximum includes
the default virtual storage machine and seven user-defined virtual storage machines. Resources in
the resource pools of user-defined virtual storage machines are added and removed by editing
the virtual storage machines. You can allocate custom roles and permissions to the resource pools
of user-defined virtual storage machines.
Virtual storage machine resources and resource groups
The following resources can be added and grouped by system resource type to the virtual storage
machine:
• Parity groups
• LDEV IDs
• Storage ports
• Host group numbers
Note the following conditions for adding resources to a virtual storage machine:
• When adding resources to the resource pool on a virtual storage machine, the same conditions
and prerequisites for creating resource groups apply.
• LDEV IDs or host group numbers can be added only if they are not allocated to a host and do not
have virtual information.
User-defined resource groups defining more specific storage access can be created for the XP7. You
create a resource group on a virtual storage machine by allocating resources from the resource pool.
You can check the resource pools on separately created virtual storage machines from the resource
group list.
