Adding A Member Virtual Disk To A Consistency Group

To add a new base virtual disk to an existing consistency group, specify an existing repository virtual disk for the new consistency group member or create a new repository virtual disk. When creating a new repository virtual disk, identify an existing disk group or disk pool in which to create the repository virtual disk.
To add a new base virtual disk to a consistency group with an existing virtual disk: 
set consistencyGroup ["
                                    consistencyGroupName"] addCGMemberVirtualDisk="
                                    baseVirtualDiskName" repositoryVirtualDisk="repos_XXXX"
To add a new base virtual disk to a consistency group and create a new repository virtual disk using a disk group: 
set consistencyGroup ["
                                    consistencyGroupName"] addCGMemberVirtualDisk="
                                    baseVirtualDiskName" repositoryVirtualDisk=("
                                    diskGroupName" capacity=capacityValue(KB|MB|GB|TB|bytes))
To add a new base virtual disk to a consistency group and create a new repository virtual disk using a disk pool: 
set consistencyGroup ["
                                    consistencyGroupName"] addCGMemberVirtualDisk="
                                    baseVirtualDiskName" repositoryVirtualDisk=("
                                    diskPoolName" capacity=capacityValue(KB|MB|GB|TB|bytes))

Restrictions

  • The Snapshot premium feature must be enabled on the storage array.
  • To add a new member virtual disk, the consistency group must fewer than the maximum number of virtual disks allowed in your configuration.
  • If the base virtual disk resides on a standard disk group, the repository members for any associated consistency group can reside on either a standard disk group or a disk pool. If a base virtual disk resides on a disk pool, the repository members for any associated consistency group must reside on the same disk pool as the base virtual disk.
  • You cannot add a virtual disk to a consistency group that is in a Failed state.
