information, and those for which the HP Matrix Default Storage Template was chosen. Enabling
on-demand provisioning is typically done in conjunction with a capacity constraint (for example,
no more than 256 GB) and that constraint applies to all requests using the default template.
This allows the constraint to be applied to only on-demand provisioned volumes and not
pre-provisioned volumes.
• By creating a new template and enabling on-demand provisioning for that new template (with
a capacity constraint). On-demand provisioning is used for those IO service templates that
select this storage template.
IMPORTANT: Use caution when making changes to the default Matrix template because those
changes impact all such requests. For example, if you were to set a maximum size of 100 GB for
that template, no manual path could fulfill through SPM with a volume larger than 100 GB. Similarly,
if you want to enable on-demand provisioning for all manual requests, you would do so by modifying
the default Matrix template and perhaps impose a capacity constraint such as no on-demand
provisioned volume can exceed 500 GB but pre-provisioned volumes have no size limitations.
To enable on-demand storage provisioning:
1. Log in to Storage Provisioning Manager. You must be a storage administrator to enable
on-demand storage provisioning.
To start SPM, open an internet browser to https://localhost:8000, where “localhost” is the
name of your CMS.
2. Select Templates under Storage Services.
3. Search for and select HP Matrix Default Storage Template in the list of templates, or click
Create Template to create a new template.
4. Click Edit Template.
5. In the Edit Template dialog, select the Read-Only Requirements tab.
