7.3 Spare Chunklets 7.2

The purpose of this chapter is to provide an overview of chunklets.

7.1 Overview

Physical disks are divided into chunklets. When a physical disk is admitted to the storage server

it is divided into chunklets that become available to the system. Some chunklets are used by

logical disks and other chunklets are designated as spares to hold relocated data during a disk

failure or during maintenance procedures.

Creating, moving, and removing chunklets and spares can only be performed with the 3PAR

InForm Command Line Interface (CLI). Refer to the 3PAR InForm OS CLI Administrator’s Manual

for instructions on how to perform these tasks.

Viewing chunklets and spares can be performed with both the 3PAR InForm Command Line

Interface (CLI) and the 3PAR InForm Management Console. Refer to the 3PAR InForm OS CLI

Administrator’s Manual and the 3PAR InForm Management Console Online Help for

instructions on how to perform this task.
