Creating example volumes

Use the following command to create a 10 GB concatenated volume:

# vxassist -g exdg -P expool make vol1 10g

Use the following command to create a 2-way mirrored volume using rules:

# vxassist -g exdg -P expool make vol1 10g rules='mirror 2'

Use the following command to create a 7-column striped volume using rules:

# vxassist -g exdg -P expool make vol1 10g rules='stripe 7'

Use the following command to create a 2-way mirrored volume using the DataMirroring capability:

# vxassist -g exdg -P expool make vol1 10g \

  capability='DataMirroring(nmirs=2)'

Use the following command to create a 2-way mirrored volume with each mirror on a separate enclosure:

# vxassist -g exdg -P expool make vol1 10g \

  capability='DataMirroring(nmirs=2),\

  MirrorsOnSeparateComponents(component="Enclosure")'

Use the following command to create a 2-way mirrored volume that is enabled for the creation of instant snapshots:

# vxassist -g exdg -P expool make vol1 10g \

  capability='DataMirroring(nmirs=2), InstantSnapshottable'

Use the following command to create a volume using only disks from enclosure e1:

# vxassist -g exdg -P expool vol1 10g \

  rules='confineto "Enclosure"="e1"'

or alternatively:

# vxassist -g exdg -P expool make vol1 10g \

  capability='ConfineToSpecificStorage(name="Enclosure",\

  value="e1")'

Use the following command to create a volume using disks on the same controller:

# vxassist -g exdg -P expool make vol1 10g \

  rules='confineto "Controller"'

or alternatively:

# vxassist -g exdg -P expool make vol1 10g \

  capability='ConfineToSimilarStorage (name="Controller")'

Use the following command to create a RAID-5 volume with a 2-way mirrored RAID-5 log and a 2-way mirrored DCO volume:

# vxassist -g exdg -P expool make vol1 10g \

  capability='Raid5Capability,\

Raid5LogMirroring(nlogs=2), DCOLogMirroring(nlogs=2)'

Use the following command to 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):

# vxassist -g exdg -P expool make vol1 10g \

  capability='PrefabricatedRaid5'

Use the following command to create a striped volume with a minimum of 10 columns using mirrored LUNs from enclosure e1, and for which instant snapshots can be taken:

# vxassist -g exdg -P expool make vol1 10g \

  capability='PrefabricatedDataMirroring, Striping(ncols=10),\

InstantSnapshottable' rules='confineto "Enclosure"="e1"'

or alternatively:

# vxassist -g exdg -P expool make vol1 10g \

  capability='PrefabricatedDataMirroring, Striping(ncols=10),\

InstantSnapshottable,\

ConfineToSpecificStorage(name="Enclosure",value="e1")'

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

# vxassist -g exdg -P expool make vol1 10g \

  capability='DataMirroring(nmirs=2),InstantSnapshottable,\

ConfineMirrorsToSimilarStorage(name="Enclosure")'
