Concerning TPVVs, ESX VMFS-3 does not write data to the entire volume at initialization and it
can be used with TPVVs without any configuration changes to VMFS. A further examination of this
subject, recommendations, and limitations are explored in the HP document 3PAR Utility Storage
with VMware vSphere.
Creating a VLUN for Export
Creation of a VLUN template enables export of a VV as a VLUN to one or more ESX hosts. There
are four types of VLUN templates:
• port presents - created when only the node:slot:port are specified. The VLUN
is visible to any initiator on the specified port.
• host set - created when a host set is specified. The VLUN is visible to the initiators of
any host that is a member of the set.
• host sees - created when the hostname is specified. The VLUN is visible to the initiators
with any of the host’s WWNs.
• matched set - created when both hostname and node:slot:port are specified.
The VLUN is visible to initiators with the host’s WWNs only on the specified port.
You have the option of exporting the LUNs through the HP 3PAR Management Console or the
HP 3PAR OS CLI.
Using the HP 3PAR Management Console
1. From the Menu bar, select Actions→Provisioning→VLUN→Create VLUN.
2. Use the Export Virtual Volume dialog box to create a VLUN template.
Using the HP 3PAR OS CLI
To create a port presents VLUN template, issue the following command:
# createvlun [options] <VV_name | VV_set> <LUN> <node:slot:port
To create a host sees or host set VLUN template, issue the following command:
# createvlun [options] <VV_name | VV_set> <LUN> <host_name/set>
To create a matched set VLUN template, issue the following command:
# createvlun [options] <VV_name | VV_set> <LUN> <node:slot:port>/<host_name>
To create a host set VLUN template, issue the following command:
# createvlun [options] <VV_name | VV_set> <LUN> <host_set>
Here is an example:
# createvlun -cnt 5 TESTLUNs.0 0 hostname/hostdefinition
or:
# createvlun -cnt 5 TESTVLUN.0 0 set:hostsetdefination
