NOTE:
To create thinly provisioned virtual volumes, an HP 3PAR Thin Provisioning license
is required.
Consult the InForm Management Console help and the HP 3PAR Command Line Reference
for complete details on creating volumes for the InForm OS version that is being used on the
HP 3PAR Storage System. Note that the commands and options available for creating a virtual
volume may vary for earlier versions of the InForm OS.
Creating Thin Provisioned Volumes
To create Thin Provisioned volumes, see the following documents:
•
HP 3PAR InForm OS Concepts Guide
•
HP 3PAR InForm OS CLI Administrator’s Manual
•
InForm OS 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 Virtual LUNs, issue the following command:
createvlun -cnt <number> <VV_name> <LUN> <host_name>
where:
•
-cnt <number>
specifies that a sequence of VLUNs, as specified by the
number
argument,
are exported to the same system port and host that is created. The
number
argument can be
specified as any integer. For each VLUN created, the
.int
suffix of the VV_name specifier
and LUN are incremented by one.
•
<VV_name>
specifies name of the virtual volume being exported as a virtual LUN.
•
<LUN>
indicates that this is the starting LUN number.
•
<hostname/hostdefinition>
indicates that hostname is the name of the host created in
sections 2.1.1, 2.1.2, or 2.1.3.
Example:
# createvlun -cnt 5 TestLUNs.0 1 hpux-host
To verify that VLUNs have been created, issue
showvlun
:
# showvlun
