Creating Volumes

Create a 10-gigabyte concatenated volume:


vxvoladm -g exdg make vol1 10g

Create a 2-way mirrored volume using rules:


vxvoladm -g exdg make vol1 10g rules='mirror 2'

Create a 7-column striped volume using rules:


vxvoladm -g exdg make vol1 10g rules='stripe 7'

Create a 2-way mirrored volume using the DataMirroring capability:


# vxvoladm -g exdg make vol1 10g \
capability='DataMirroring(nmirs=2)'

Create a 2-way mirrored volume with each mirror on a separate enclosure:


# vxvoladm -g exdg make vol1 10g \
capability='DataMirroring(nmirs=2),\
MirrorsOnSeparateComponents(component="Enclosure")'

Create a 2-way mirror volume that is enabled for the creation of instant snapshots:


# vxvoladm -g exdg make vol1 10g \
capability='DataMirroring(nmirs=2), InstantSnapshottable'

Create a volume using only disks from enclosure e1:


vxvoladm -g exdg make vol1 10g rules='confineto "Enclosure"="e1"'
or alternatively:

# vxvoladm -g exdg make vol1 10g \
capability='ConfineToSpecificStorage(name="Enclosure",\
value="e1")'

Create a volume using disks on the same controller:


vxvoladm -g exdg make vol1 10g rules='confineto "Controller"'
or alternatively:

# vxvoladm -g exdg make vol1 10g \
capability='ConfineToSimilarStorage (name="Controller")'

Create a RAID-5 volume with a 2-way mirrored RAID-5 log and a 2-way mirrored DCO volume:


# vxvoladm -g exdg make vol1 10g capability='Raid5Capability,\
Raid5LogMirroring(nlogs=2), DCOLogMirroring(nlogs=2)'

Create a volume using a RAID-5 device that has been implemented in hardware (such as a RAID-5 LUN in an EMC Symmetrix array):


vxvoladm -g exdg make vol1 10g capability='PrefabricatedRaid5'

Create a striped volume with a minimum of 10 columns using mirrored LUNs from enclosure e1, and for which instant snapshots can be taken:


# vxvoladm -g exdg make vol1 10g \
capability='PrefabricatedDataMirroring, Striping(ncols=10),\
InstantSnapshottable' rules='confineto "Enclosure"="e1"'
or alternatively:

# vxvoladm -g exdg make vol1 10g \
capability='PrefabricatedDataMirroring, Striping(ncols=10),\
InstantSnapshottable,\
ConfineToSpecificStorage(name="Enclosure",value="e1")'

Create a 4-way mirrored volume in which each mirror uses disks from the same enclosure, and for which instant snapshots can be taken:


# vxvoladm -g exdg make vol1 10g \
capability='DataMirroring(nmirs=2),InstantSnapshottable,\
ConfineMirrorsToSimilarStorage(name="Enclosure")'
