Organizing storage pools in a disk group

Before you can use ISP to create volumes in a disk group, you must first create any storage pools that you require in that disk group. A storage pool has associated disks, templates and policies. These policies control how the disks and templates are used when allocating storage from the pool to volumes.

The vxpool organize command simplifies the initial creation of one or more pools in a disk group by using a storage pool set definition. You can use this command to create a set of pools with policies and templates that are designed for a variety of different applications. A storage pool set consists of one data pool definition and one or more clone pool definitions. Each of these pool definitions typically consists of the pool type, the templates that the pool contains, and the pool policies.

For example, if you want your data volumes to be mirrored for redundancy, and your snapshot volumes to be striped for performance, you can choose a storage pool set definition where the data pool has associated templates that relate to mirroring, and the clone pool has associated templates that relate to striping. A suitable choice would be the mirrored_data_striped_clones storage pool set.

To create these storage pools within a disk group, use the following command:

# vxpool -g diskgroup organize mirrored_data_striped_clones
