Keywords used are make , mirror , move , growto ,growby ,shrintto ,shirnkby ,snapstart , snapshot ,snapwait
Attributes specify volumes layout disks controllar to include exclude etc
Creating a Concatenated Volume
By default, vxassist creates a concatenated volume using the space available on a disk or on the number of disks in a diskgroup if the volume size specified is more then the one available on a single disk.
Disks can be specified from a diskgroup for a volume group but if not mentioned available disks are selected by the volume manager.
Command syntax :
To create a new volume appvol of 100 MB in the default disk group rootdg with available disks:
To create the volume appvol of 100MB on disk03
Creating a Striped Volume
A striped volume contains at least one plex that consists of two or more subdisks located on two or more physical disks.
Command Syntax :
To create a striped volume appvol2 with the default stripe unit size on the default number of disks
To create a striped volume appvol2 100MB striped volume on three specific disks.
Creating a RAID-5 Volume
A RAID-5 volume contains a RAID-5 plex that consists of two or more subdisks located on two or more physical disks. Only one RAID-5 plex can exist per volume. A RAID-5 volume may also contain one or more RAID-5 log plexes, which are used to log information about data and parity being written to the volume.
Command Syntax :
To create the RAID-5 volume appvol4 with the default stripe unit size on the default number of disks with RAID-5 log,
vxassist <option> <Keyword> volume_name [attributes]Commonly used options are given below (See man vxassist for complete list of supported options)
-g for specifying diskgroups
-b for background operation
-d file containing defaults for vxassist if not specified /etc/default/vxassist is used

Disks can be specified from a diskgroup for a volume group but if not mentioned available disks are selected by the volume manager.
Command syntax :
vxassist make volume_name volume_lengthTo create a new volume appvol of 100 MB in the default disk group rootdg with available disks:
#vxassist make appvol 100m
To create the volume appvol of 100MB on disk03
#vxassist make appvol 100m disk03
Creating a Striped Volume
A striped volume contains at least one plex that consists of two or more subdisks located on two or more physical disks.
Command Syntax :
vxassist make volume_name length layout=stripeTo create a striped volume appvol2 with the default stripe unit size on the default number of disks
#xassist make appvol2 100m layout=stripe
To create a striped volume appvol2 100MB striped volume on three specific disks.
#vxassist make appvol2 100m layout=stripe disk04 disk05 disk06
