4 Allocating Storage for Access by the HP-UX Host
Creating Storage on the HP 3PAR Storage System
This section describes the general steps and commands that are required to create the Virtual
Volumes that can then be exported for discovery by the HP-UX host. For additional information,
see the HP 3PAR InForm OS CLI Administrator’s Manual. For complete details on creating Virtual
Volumes, see the appropriate HP 3PAR documentation.
Creating Virtual Volumes
Virtual Volumes are the only data layer visible to hosts. After devising a plan for allocating space
for host servers on the HP 3PAR Storage System, create the Virtual Volumes.
After devising a plan for allocating space for the HP-UX host, you need to create the required
Virtual Volumes on the HP 3PAR Storage System. You can create volumes that are provisioned
from one or more Common Provisioning Groups (CPGs). Volumes can be fully provisioned from
a CPG or can be thinly provisioned. You can optionally specify a CPG for snapshot space for fully
provisioned volumes.
Using the InForm Management Console:
1.
From the Menu bar, select:
Actions
→
Provisioning
→
VV
→
Create Virtual Volume
2.
Use the
Create Virtual Volume
wizard to create a base volume.
3.
Select one of the following options from the
Provisioning
list:
•
Fully Provisioned from PDs
•
Fully Provisioned from CPG
•
Thinly Provisioned
Using the InForm CLI:
To create a fully provisioned or thinly provisioned virtual volume, issue the following InForm
CLI command:
createvv [options] <usr_cpg> <vvname> [.<index>] <size>[g|G|t|T]
Here is an example:
# createcpg CPG_test
# createvv -cnt 5 CPG_test TestLUNs 5g
# showvv
