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 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 7).
Example:
# createvlun -cnt 5 TestLUNs.0 1 hpux-host
To verify that VLUNs have been created, issue the showvlun command:
# showvlun

SCSI Enclosure Services (SES) LUN Considerations
HP 3PAR OS 3.1.3 and newer will, for HP-UX Host Persona 13, automatically present a SCSI
Enclosure Services (SES) LUN 254 to the host. If a data Virtual Volume (VV) is subsequently
presented/unpresented as LUN 254, system administrator actions are required to complete the
