II13129: SHARED HFS SYSTEM-SPECIFIC AUTOMOVE OMVS OWNERSHIP

APAR status

• INTRAN

Error description

• In the UNIX System Services Planning manual, there are several
  statements about ownership and the AUTOMOVE parameter for the
  system-specific file systems (/dev, /etc/, /tmp, /var). The pur-
  pose of this INFO APAR is to expand on the explanation using the
  /dev system-specific file system as an example. The UNIX System
  Services Planning manual does state that the system-specific
  file systems should not be mounted with the AUTOMOVE=YES param-
  ter, nor should they be moved to a system other than the proper
  owner. In this example, the /dev system-specific file system
  was mounted via BPXPRMxx as AUTOMOVE=YES (the default). As a
  result of a scheduled IPL, ownership of this /dev file system
  moved to another system in the shared HFS sysplex. When users
  tried to enter the OMVS shell on the original system (proper
  owner of the /dev system specific file system), they received:
  FSUM2150I Function = stat(), ending name = '/dev/ptyp0257', retu
  = -1,
   errno = 129 (X'00000081'), reason code = 053B006C, description
  'EDC5129I No s
  uch file or directory.'
   FSUM2164I Function = open(), terminal name = '/dev/ptyp0000', r
  value = -1
  , errno = 128 (X'00000080'), reason code = 0562004B, description
  'EDC5128I No
  such device.'
  .
  Full function was restored by unmounting the file system and
  mounting it to the correct owner.
  Additional symptom: OMPROUTE fails with RC1. OMPROUTE uses the
  /dev/null file; a change in the ownership of the /dev file
  system will result in a failure in OMPROUTE. Ensure that the
  system where OMPROUTE runs is the owner of the /dev file system.
  .
  Note that in a DFS/SMB environment, the setting of the  server
  configuration option _IOE_MOVE_SHARED_FILESYSTEM may affect the
  ownership of file systems.
