IC72244: MULTIPLE PATH DEFINITIONS TO A LIBRARY FROM THE SAME SOURCE TYPE MIGHT CAUSE ANR8840E

APAR status

• Closed as fixed if next.

Error description

• The Tivoli Storage Manager server documentation specifies that
  only one source can access a library in the DEFINE LIBRARY
  command documentation.
  However, it is possible to define a path from more than one
  source type to the same library device on a library manager.
  This should be prevented. For example, a user defined a path
  from the library manager and library client to the same
  library device. This is the query path output:
  TSMLM        TAPELIB2       /dev/lb2   YES
  TSMLC        TAPELIB2       /dev/lb2   YES
  There should never be more than a single path to a library
  device from the same source type. In this case, the source
  type is SERVER. There should only be a single path defined
  from a machine identified as a library manager or data mover.
  This condition might cause errors similar to this:
  ANR8840E Unable to open device /dev/lb0 with file handle
  16 and PVRRC 153. (SESSION: XXXX)
  Note that in this case "file handle 16" should read
  "errno 16". A trace will show this. Errno 16 is defined
  as:
  #define EBUSY 16 /* Resource busy */
  This error can also be caused by other software opening
  the library device. The library manager or data mover
  should be the only machine(s) which open the library
  device. It is not supported to allow other machines or
  software to open the library device while in use by
  the Tivoli Storage Manager software.
  Tivoli Storage Manager Versions Affected:
  5.4, 5.5, 6.1, 6.2 on all platforms
  Initial Impact:
  Medium
  Additional Keywords:
  TSM MSGANR8840E error number 16 define path srct destt
  

Local fix

• Do not define more than one path to a library device from
  the same source type.
