NAME

       dmmp_path_status_get - Retrieve the path status.

SYNOPSIS

       uint32_t dmmp_path_status_get (struct dmmp_path *dmmp_p);

ARGUMENTS

       dmmp_p      Pointer  of 'struct dmmp_path'.  If this pointer is NULL, your program will be
                   terminated by assert.

DESCRIPTION

       The valid path statuses are:

       * DMMP_PATH_STATUS_UNKNOWN

       * DMMP_PATH_STATUS_DOWN

       Path is down and you shouldn't try to send commands to it.

       * DMMP_PATH_STATUS_UP

       Path is up and I/O can be sent to it.

       * DMMP_PATH_STATUS_SHAKY

       Only emc_clariion checker when path not available for "normal" operations.

       * DMMP_PATH_STATUS_GHOST

       Only hp_sw and rdac checkers.  Indicates a "passive/standby"  path  on  active/passive  HP
       arrays.   These   paths   will  return  valid  answers  to  certain  SCSI  commands  (tur,
       read_capacity, inquiry, start_stop), but will  fail  I/O  commands.   The  path  needs  an
       initialization command to be sent to it in order for I/Os to succeed.

       * DMMP_PATH_STATUS_PENDING

       Available for all async checkers when a check IO is in flight.

       * DMMP_PATH_STATUS_TIMEOUT

       Only tur checker when command timed out.

       * DMMP_PATH_STATUS_DELAYED

       If a path fails after being up for less than delay_watch_checks checks, when it comes back
       up again, it will not be marked as up until it has been up for  delay_wait_checks  checks.
       During this time, it is marked as "delayed".

RETURN

       uint32_t.
