vxvol [-g<DynamicDiskGroupName>] autogrow<VolumeName|DriveLetter|VmName|DrivePath> enable=<yes|no> [growby=<length>] [-t tpdiskonly] [maxvolumesize=<#size>] [email=<email address>] [<alloc_attributes...>] [<diskname|p#c#t#l#>...] [-A APPLYPOLICYTOFAILOVER]

Allows an individual volume to grow (increase capacity) automatically by a specified amount when the used disk space on the volume reaches a certain threshold. The threshold is set by Capacity Monitoring.

The following attributes apply:

-g<DynamicDiskGroupName>

Name of dynamic disk group. (Needed only if you use the internal disk name of the volume.)

VolumeName

The path name of the volume, such as \Device\HarddiskDmVolumes\DG1\Volume1

DriveLetter

Drive letter of the volume.

VmName

The internal disk name of the volume, which requires the -g option (for example, -gDG1 Volume2).

DrivePath

Drive path that the volume is mounted on. (Must be an empty folder on a local NTFS volume.)

Enable

Enable or disable automatic volume growth.

growby

Amount of space that volume is to be expanded each time the growth threshold is reached. Amount of space can be specified in terms of S for Sectors, K for KBs, M for MBs, G for GBs, T for TBs. The default unit of measurement is MBs.

-t tpdiskonly

Specify for only thin provisioned disks.

maxvolumesize

Maximum volume size. Limit volume growth to a maximum volume size. Maximum volume size can be specified in terms of S for Sectors, K for KBs, M for MBs, G for GBs, T for TBs. The default is unrestricted volume growth.

email

Notification email address when volume capacity has reached warning/critical threshold.

<alloc_attributes...>

Specify allocation attributes for mirror/stripe volumes. Attributes are of the form: mirror={diskclass} wantmirror={diskclass} stripe={diskclass} wantstripe={diskclass}

Mirror

Specify the diskclass to use for mirroring.

WantMirror

Specify the diskclass to use for mirroring. This specification is ignored if allocations are not available.

Stripe

Specify that volumes are to be striped across instances of a diskclass.

WantStripe

Specify that volumes are to be striped across instances of a diskclass. This specification is ignored if allocations are not available.

diskclass

Type of disk grouping to be used for mirror/stripe. Available types are channel, enclosure, port, or target.

diskname

Name of the disk, e.g., Harddisk2; or internal disk name (requires use of -g option), e.g., -g MyDg Disk2

p#c#t#l#

Corresponds to the Port, Channel, Target, LUN of a disk.

-A APPLYPOLICYTOFAILOVER

Make capacity monitoring policy available to another cluster node after a failover.
