Creating Thinly-provisioned Virtual Volumes
To create thinly-provisioned virtual volumes (TPVVs), see the following documents:
• HP 3PAR StoreServ Storage Concepts Guide
• HP 3PAR Command Line Interface Administrator’s Manual
• HP 3PAR Command Line Interface Reference

Exporting LUNs to the Host
This section explains how to export LUNs to the host as VVs, referred to as virtual LUNs (VLUNs).
To export VVs as VLUNs, issue the following command:
createvlun [–cnt] <number of LUNs> <name_of_virtual_LUNs> [.int] <starting_LUN_number> <hostname/hostdefinition>
where:
• [–cnt] Specifies the number of identical virtual volumes to create using an integer from 1
through 999. If not specified, one virtual volume is created.
• <name_of_virtual_LUNs> specifies name of the virtual volume being exported as a VLUN.
• <starting_LUN_number> indicates that is the starting LUN number.
• <hostname/hostdefinition> indicates that hostname is the name of the host created in
“Creating the Host Definition” (page 10) or “Creating the Host Definition” (page 12).
Example:
# createvlun –cnt 5 TESTLUN.0 0 susehost
To verify that VLUNs have been created:
# showvlun

In the example above, there are five paths to the HP 3PAR StoreServ Storage from each HBA port.
