Chapter 5

Creating and administering subdisks

This chapter describes how to create and maintain subdisks. Subdisks are the low-level building blocks in a Veritas Volume Mananger (VxVM) configuration that are required to create plexes and volumes.

Note: Most VxVM commands require superuser or equivalent privileges.

Creating subdisks

Note: Subdisks are created automatically if you use the vxassist command or the Veritas Enterprise Administrator (VEA) to create volumes. For more information, see “Creating a volume” on page 238.

Use the vxmake command to create VxVM objects, such as subdisks:

#vxmake [-gdiskgroup] sd subdisk diskname,offset,length

where: subdisk is the name of the subdisk, diskname is the disk name, offset is the starting point (offset) of the subdisk within the disk, and length is the length of the subdisk.

For example, to create a subdisk named mydg02-01in the disk group, mydg, that starts at the beginning of disk mydg02 and has a length of 8000 sectors, use the following command:

# vxmake -g mydg sd mydg02-01 mydg02,0,8000
