HP Matrix Operating Environment 7.3 and 7.3 Update 1 Logical Server Management User Guide

You can globally define a storage tag and associate it with storage pool entries by pressing
Manage Tags on the Manage Storage Pools screen. This allows you to group storage pool entries
together, which becomes more important as the number of pool entries increases.
See “Defining storage for logical servers” (page 43) for more information.
NOTE: The storage tags apply at the level of the storage pool entry for all volumes within that
storage pool entry. If you need separate tags for different storage volumes, they should be in
separate storage pool entries (but that will consume more initiator WWNs).
Manage portability groups
The Modify→Logical Server Portability Groups... menu selection allows you to select systems from
Matrix OE visualization Physical and Virtual perspective that you want to include in a user-defined
portability group. A portability group defines the move and portability constraints of a logical
server.
NOTE: When using portability groups, consider the following:
• A portability group member can be removed at any time as long as it belongs to a user-defined
portability group, even if there are logical servers using it. (The member that was removed is
no longer a suitable target for the logical server.)
• A member of a user-defined portability group will always be one of the default portability
group members, so removing it will not affect the datacenter.
• If you want to reactive a logical server in a previously removed user-defined portability group,
you must modify the logical server to point to a different portability group.
Default portability groups are:
• Each VC Domain Group
• Each Operations Orchestration Workflow physical server
• All ESX Virtual Machine Hosts
• All Hyper-V Virtual Machine Hosts
• All HP Integrity VM Virtual Machine Hosts
NOTE: Default portability groups cannot be modified.
(Optional) User-defined portability groups are:
• A single VC Domain Group
• A set of ESX Virtual Machine Hosts
• A set of Hyper-V Virtual Machine Hosts
• A set of HP-UX vPars and Integrity VM VSPs
• A set consisting of a single VC Domain Group and set of similar VM Hosts (either ESX, Hyper-V,
HP vPars or Integrity VM).
A logical server created in this type of portability group is a cross-technology logical server.
You may want to create a user-defined portability group to:
• Enable cross-technology moves of logical servers, for example, from a server with Virtual
Connect to an ESX virtual machine.
• Limit the number of servers or hypervisors contained in a portability group. For example, if
the default “All ESX hypervisors” portability group contains a large number of virtual machines,
you can create a portability group that contains a smaller number of ESX VM Hosts within
which logical servers can move. This may have the additional benefit of reducing the number
of rejected targets when you move the logical server.
