Checking that newly presented EMC disks have been found by the OS. This avoids doing a full devfsadm.

• Find the syms in the dev group # symdg show device_group


• Find the identifier of a new disk

  # symmaskdb -sid 271 -dev 1A6B list assignment
  Symmetrix ID : 000287890271
  
  Device  Identifier        Type   Dir:P
  ------  ----------------  -----  ----------------
  1A6B    210100e08ba1b1e5  FIBRE  FA-7A:0
          210100e08ba104ec  FIBRE  FA-10A:0




• Find the FA's WWNs

  # symcfg -sid 271 list -fa 7A -p 0
  Symmetrix ID: 000287890271
  
             S Y M M E T R I X    F I B R E   D I R E C T O R S
  
      Dir    Port  WWN               VCM      Volume Set   Pnt to Pnt
                                     Enabled  Addressing
  
      FA-7A   0    500604844a36d7c6  Yes      No           Yes



• And

   # symcfg -sid 271 list -fa 10A -p 0
  
  Symmetrix ID: 000287890271
  
             S Y M M E T R I X    F I B R E   D I R E C T O R S
  
      Dir    Port  WWN               VCM      Volume Set   Pnt to Pnt
                                     Enabled  Addressing
  
      FA-10A  0    500604844a36d7c9  Yes      No           Yes




• Find the controllers that the FA's are connected to

  cfgadm -al  | egrep "500604844a36d7c6|500604844a36d7c9"
  c7::500604844a36d7c9           disk         connected    configured   unknown
  c13::500604844a36d7c6          disk         connected    configured   unknown



• Configure those adapters/FA's so that the disks are found

  # cfgadm -v -c configure c7::500604844a36d7c9
  # cfgadm -v -c configure c13::500604844a36d7c6

  Both paths should now be visible.
