IT35391: MANAGED CAPACITY NOT DISPLAYED CORRECTLY BECAUSE BACKEND STORAGE IS NOT BEING SHOWN AS VIRTUALIZED

APAR status

• Closed as program error.

Error description

• DETAIL OF PROBLEM :
  
  Storage Insights and Spectrum Control are counting backend
  storage as non-virtualized and unmanaged because it is unable
  to correlate it with the Virtualizer it is connected to.
  
  Specifically in this case the SVC device has V7000 backend
  storage device which is connected via NPIV FC ports that is not
  correctly correlated to the SVC virtualizer and causing the
  backend device to be seen as unmanaged Controller.
  
  Storage Insights and Spectrum Control should report the missing
  correlation of virtualizer to backend subsystems when they are
  connected through FC NPIV ports
  
  Currently Spectrum Control and Storage Insights do not
  support use of NPIV FC ports.
  
  ____________________________________________________
  The defect is against component:  5608TPCSI
  
  Server/Manager build/release:  5.4.1
  
  Problem as described by customer:
  Managed capacity is showing as much higher than expected and
  raised concern of being charged for falsely reported capacity.
  
  Initial customer impact (low/med/high):  low
