VERITAS Volume Manager 3.5 Administrator's Guide (September 2004)

Chapter 2 65

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.

NOTE 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 85 for more information.

NOTE 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 105.
