Compacting Common Provisioning Groups
Reclaim unused CPG space with the compactld command. CPGs provide a shared pool of LD
capacity for use by all virtual volumes that draw space from that pool. If volumes that draw from
a CPG are deleted, or if copy space for these volumes grows and then shrinks, the underlying LDs
in the CPG pool can become less efficient in space usage. Compacting a CPG allows you to
reclaim space from a CPG that has become less efficient in space usage from creating, deleting,
and relocating volumes. Compacting consolidates LD space in CPGs into as few LDs as possible.
• compactcpg <CPG_name> or compactcpg <pattern>
◦ <CPG_name> is the name of the CPG you wish to compact.
◦ <pattern> displays all CPGs that match the pattern.
See the HP 3PAR Command Line Interface Reference and the HP 3PAR CLI Help for detailed
information about this command.
