Expanding THP/Smart pools

Pool capacity can be increased by expanding THP/Smart pools or by converting THP pools into Smart
pools.

Expand a THP/Smart pool by adding volumes to it. Expand an existing THP pool by converting it into
an Smart pool, which changes the pool type and allows you to configure tiers that support a mix of
drive types and RAID levels.

Prerequisites

Register the storage system.

Verify the external connections for any storage system with multiple performance levels before
defining an external LDEV tier rank.

Verify that when using HP XP7, HP XP24000/20000, or HP XP P9500 Storage for THP/Smart
pools:
• Parity groups from which volumes have already been created can be added
• Drive type characteristics (for example: drive type and drive speed) in parity groups and RAID

level

NOTE:

In Smart pools, if different drive types and/or RAID levels are mixed in a single tier, they will all be
considered equal for data placement regardless of page access frequency. As a result, I/O performance
will be dependent on the drive type characteristics and RAID level on which any given page resides.

NOTE:

In THP pools, if different drive types and/or RAID levels are mixed in an THP pool, I/O performance
will be dependent on the drive type characteristics and RAID level on which any given page resides.
