5.Creating a Volume on Any Disk
# vxassist -b make voldefault 10g
6.Creating a Volume on Specific Disks
# vxassist -b make volspec 5g disk03 disk04
#vxassist -b -g dgrp maxsize layout=raid5 nlog=2 !disk07 !disk08
***********************************
To rename disk03 to rootdisk, use the following command:
#vxedit rename disk03 rootdisk
To reserve a disk for special purposes, use the following command:
#vxedit reserver=on disk03
#vxassist make vol03 2000m disk03
To turn off reservation of a disk, use the following command:
#vxedit reserve=off disk03
For example, to remove disk02 from rootdg, use this command:
# vxdg rmdisk disk02
For example, to remove c1t0d0s2 from VxVM control, use these commands:
#vxdisk rm c1t0d0s2
