Creating Volumes

186 VERITAS Storage Foundation ISP Administrator’s Guide

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")'
