HP 3PAR InForm OS 3.1.1 Concepts Guide

• For automatic relocations, the system uses up a maximum of one disk worth of chunklets per
system node.
• When selecting a target chunklet for relocation, the system attempts to identify a local spare
chunklet, a local free chunklet, a remote spare chunklet, and then finally a remote free chunklet.
NOTE: Local chunklets are chunklets on disks whose primary path is connected to a node that
owns the logical disk containing the chunklets being relocated.
• If the system uses up its free or spare chunklets for relocation, an alert is generated.
• Once the spare and free chunklets are used up, automatic relocation no longer occurs. In
most cases, some data redundancy is lost. The system also generates an alert.
