Using Disk Groups

Most Volume Manager commands allow you to specify a disk group using

the –g option. For example, to create a volume in disk group mktdg, use

the following command:

# vxassist

-g mktdg make mktvol 50m

The (block) volume device for this volume is:

/dev/vx/dsk/mktdg/mktvol

The disk group does not have to be speciﬁed. Most Volume Manager

commands use object names speciﬁed on the command line to determine

the disk group for the operation. For example, to create a volume on disk

mktdg01 without specifying the disk group name, use the following

command:

# vxassist make mktvol 50m mktdg01

Many commands work this way as long as two disk groups do not have

objects with the same name. For example, the Volume Manager allows

you to create volumes named mktvol in both rootdg and in mktdg.

Remember to add –g mktdg to any command where you want to

manipulate the volume in the mktdg disk group.
