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.
