Error description

• Internal lock contention on the server sometimes causes it to
  report that storage agent LANFREE paths do not exist.
  
  This incorrectly causes data to be transferred through the
  server and over the LAN.
  
  This can also cause excessive sessions to be opened with the
  library manager server in order to re-check if a LANFREE path
  exists every time a client session connects.
  
  
  
  Customer/L2 Diagnostics:
  
  If data read/write path is LANFREE only operation may fail with
  ANR0416W and ANS0350E on client side.
  
  If LAN is allowed the request will go over the LAN.
  It could be determined using 'bytes transferred' value for LAN
  session from 'QUERY SESSION' output for sessions between STA and
  Server.
  
  For example. 'QUERY SESSION' from STA:
  
  75     ShMem      SendW        0 S          5.1 G         399
  Node        AIX       <Client name>
  76     SSL             Run               0 S          848
  5.1 G     Server      AIX       <Server name>
  
  Also traces from STA will show that there is no path for Library
  Server:
  
  08:58:01.897 [72][smlshare.c][899][smQueryLibraryPath]:rc 0 as
  result of QueryLibPath pathExists is 0
  08:58:01.897 [72][pvr.c][8991][pvrTestLanFreePath]:rc 0 from
  smQueryLibraryPath library <library Name> exists is 0
  
  Here are some other traces that were found:
  
  19:07:57.399 [94][smbf.c][555][smCheckRemoteBitfile]:File
  XXXXXXXX  for vol YYYYYYY  is in pool ZZ with lanfree FALSE.
  19:07:57.399 [94][smbf.c][567][smCheckRemoteBitfile]:Returning
  REMOTE TRUE.
