VERITAS Volume Manager 4.1 Administrator's Guide

Chapter 2 63

2 Administering Disks

Introduction

This chapter describes the operations for managing disks used by the Volume Manager

(VxVM). This includes placing disks under VxVM control, initializing disks, mirroring the

root disk, and removing and replacing disks.

NOTE Most VxVM commands require superuser or equivalent privileges.

Rootability, which puts the root disk under VxVM control and allows it to be

mirrored, is supported for this release of VxVM for HP-UX. See “Rootability” on

page 88 for more information.

Disks that are controlled by the LVM subsystem cannot be used directly as

VxVM disks, but they can be converted so that their volume groups and logical

volumes become VxVM disk groups and volumes. For more information on

conversion, see the VERITAS Volume Manager Migration Guide.

For information about conﬁguring and administering the Dynamic Multipathing (DMP)

feature of VxVM that is used with multiported disk arrays, see Chapter 3, “Administering

Dynamic Multipathing (DMP),” on page 109.
