  A. Addini devices and Storaie Groups to the same parent Storaie Group is not permited.
  B. A Storaie Group must not be in a Maskini View to be modifed.
  C. Cluster is exceedini the assiined Host I/O limit.
  D. Devices are not yet associated with an SLO policy.
  A. Addini devices and Storaie Groups to the same parent Storaie Group is not permited.
