Creating a 3PAR CPG using SSMC

A CPG(Common Provisioning Group) is basically a set of policies which defines/creates a virtual pool of logical disks(LDs) that allows 3PAR virtual volumes to share the  resources and allocates space on demand. When we create thick and thin volumes, that draw space from the CPG's LD pool. By default, CPG is defined to automatically grow the LDs when the amount of available space on underlying LDs falls below a configured threshold.


When a common provisioning group is created using GUI or 3PAR CLI, its properties, such as RAID type and physical drive type, are specified. HP 3PAR operating systems automatically create the underlying logical drives for the common provisioning group that have those properties.

Lets see how can we create a 3PAR CPG using SSMC (StoreServ Management Console)

Login to SSMC using your 3PAR admin credentials

Once logged in, access the Mega Menu and select "Common provisioning Groups"

When you select common provisioning group, it will take you to the CPG screen where you can see all the available CPGs for the discovered/configured systems along with an option to "Create new CPG"

Click on Create CPG  if you want to create a new CPG on any discovered/configured StoreServ. It will take you to create CPG screen.

Create CPG has basically General and advanced option available. By default general will be visible. 

In General tab, input your CPG name and select the StoreServ node on which you want the CPG to be created, Select the disk type either FC, NL or SSD based on your requirement. Select the RAID type(1, 5 or 6). Once you have selected these, the screen will show you the estimated amount of space which can be used based on the RAID type which you have selected.

If you are more advanced user, select advanced option which will give you few more options like Set size, availability and growth  increment and warnings. To specify Set size, Availability, and Growth settings, select the Advanced options check box.

Set size specifies the number of chunklets in a raid set.

Availability basically means the Level of fault-tolerance for a logical disk. For example, magazine-level availability means that the logical disk can tolerate a drive magazine failure. Cage-level availability means that the logical disk can tolerate a drive cage failure.

By default, the growth warning and growth limit are set to none, which effectively disables these safety features.

When you have completed your choices, click Create to start the action and close the create CPG dialogue screen.

your new CPG will be available once the action is completed.
