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 AIX or IBM Virtual I/O Server Host
This section explains how to export LUNs to the host server 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 VVs 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 VV being exported as a virtual LUN.
• .int is the integer value. For every LUN created, the .int suffix of the VV name gets
incremented by one.
• <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 9) or “Creating the Host Definition” (page 10).
Example:
# createvlun –cnt 5 TESTLUNS.0 0 hostname/hostdefinition
# createvlun -cnt 5 TESTLUNa.0 0 VIOS
WARNING! If the configuration being used has two IBM Virtual I/O Servers, the LUN numbers
when exported to each of the IBM Virtual I/O Servers must be identical. If this important note is
not adhered to, data corruption will occur.
Example:
# createvlun -cnt 5 TESTLUNs.0 0 VIOS#one
# createvlun -cnt 5 TESTLUNs.0 0 VIOS#two
