Primary storage pools

Every HCP system has a pre-configured storage pool for each type of primary storage that the system is configured to use. The primary running storage pool contains the pre-configured primary running storage component, which represents all continuously spinning disks that are currently managed by the HCP nodes. For SAIN systems with spindown storage, the primary spindown storage pool contains the pre-configured primary spindown storage component, which represents all spindown-capable disks that are currently managed by the HCP nodes.

In the System Management Console, you can use the Storage page to view information about the current hardware configuration, health status, availability, capacity, and usage of the storage that’s represented by each primary storage pool.

You can also use the Storage page to view current and historical storage usage statistics for each individual primary storage pool, and you can view a comparison of the current and historical storage capacity usage statistics for all storage pools that are defined on the HCP system, including the two primary storage pools.

You can use the information that you can view on the Storage page to monitor the health and usage of each type of primary storage and determine when you need to add primary storage to an HCP system or replace storage devices that are used for primary running storage or primary spindown storage.

Note:  You cannot modify a primary storage pool in order to add, retire, or upgrade primary running storage or primary spindown storage.

To add primary storage to an HCP system either to increase primary storage capacity or to replace one or more retired storage devices, contact your authorized HCP service provider for help.

On a RAIN or SAIN system, you can use either the Storage page or the Migration page in the System Management Console to retire one or more primary storage devices. When you retire primary storage, HCP automatically updates each primary storage pool as necessary to reflect the changes in the total storage capacity and in the total number of disks represented by each primary storage pool.
