HP StorageWorks SAN Virtualization Services Platform Administrator Guide (5697-0934, May 2011)
2 Adding devices to the domain
This chapter describes how to expand your SVSP domain by the addition of licensed capacity,
arrays, DPMs, and servers. Adding servers requires that you consider the appropriate multipathing
for the operating system and switch zoning. Only presentation for an HP Enterprise Virtual Array
(EVA) and Modular Storage Array (MSA) is discussed. Please consult the vendor documentation
for other types of arrays.
NOTE: See the HP Single Point of Connectivity Knowledge (SPOCK) website at http://
www.hp.com/storage/spock for a list of SVSP-approved storage arrays. Site registration is required.
SVSP licenses
When adding devices to an SVSP domain, you may need to install additional license keys to
increase your capacity or add an additional license type. The Domain WWN is the same as the
node name of your first pair of Data Path Modules in a DPM group. A second DPM group will
have its own WWN that is different from that of the domain. License keys are obtained from the
HP website at http://webware.hp.com.
NOTE: Once the domain is configured with a WWN, the WWN cannot be changed.
VSM supports many types of permanent, InstantOn, and evaluation licenses. The type of license
determines which operations you can perform. A license is valid for performing the allowed
operations on a certain amount of capacity. The basic unit of software license capacity is 1 TB.
The 4–port LTU enables ports on the DPMs within the same DPM group. Most operations use license
capacity. For example, configuring a back—end LU as a member of a storage pool deducts the
BELU's disk capacity from your volume management licensed capacity. The following types are
available:
Table 1 VSM license types
DescriptionLicense type
Enables you to perform the following operations within one domain:
• Migrate used LUNs from SVSP-approved SAN storage systems to bring them under
VSM management.
• Create storage pools and stripes
• Use the migrate service.
• Use the sync mirror service (one source and one copy).
Volume Manager
Allows you to oversubscribe to the current Volume Manager license limit for 90 days for
the amount added. For example, if you add 10 TB to the VM license, then for 90 days
you can use 20 TB of capacity (10 TB at the source and 10 TB at the destination).
NOTE: No physical license is installed.
Migration
Enables you to perform the following operations within one domain in addition to the
basic license:
• Create PiTs and snapshots of virtual disks within the local domain.
• Use snapclones to copy virtual disks and snapshots within the local domain.
Business Copy (BC)
Enables thin provisioning support.Thin Provisioning (TP)
Enables you to perform the following operations between domains in addition to the
basic license:
• Supports remote snapclones between two domains.
• Supports remote async mirrors between a single source domain and up to three remote
domains.
