Associating a data volume with an RVG

The vxvol assoc command enables you to associate the specified data volume to the required RVG.

Volume Replicator does not support the following volumes for replication:

  • Storage Foundation (software) RAID 5 volumes

  • Volume with a Dirty Region Log (DRL)

  • Volume with a comma in the name

    Using this command, you can add only one volume at one time.

Syntax for vxvol assoc command

vxvol -g <DynamicDiskGroupName> assoc <rvg>
<Volume:DriveLetter:VmName>

Example

vxvol -g vvrdg assoc rvg vol1

The following table describes the attributes that you can specify with vxvol command.

Table: Attributes for vxvol assoc command

Attributes

Description

VolumeName

Specifies the DeviceName of the volume. For example, \HarddiskDmVolumes\<diskgroup>\<volume name>

DriveLetter

The drive letter of the existing volume.

VmName

Specifies the internal name of the volume. You can obtain this by using the vxvol volinfo <volume> command.
