Subject: [Disksim-users] question about the synthraid5.parv
Message-ID: <m2xe5f3edfc1005040208s7710497bjfe4fbe19ae415a35@mail.gmail.com>

dear dismsim-users:

i use gdb to learn out disksim.
the parameter file is synthraid5.parv ..
in isynthraid5.parv
"disksim_logorg org0 {
    Addressing mode = Array,
   Distribution scheme = Striped,
   Redundancy scheme = Parity_rotated,
"

i use gdb to debug this program with the  synthraid5.parv
(gdb --args ./disksim synthraid5.prav synthraid5.outv ascii  0 1)
when i  reach the function disksim_logorg.c:logorg_maprequest which is
called by  disksim_iodriver.c:iodriver_request
696 int logorg_maprequest (logorg **logorgs, int numlogorgs, ioreq_event *curr)
{
..............
773  if (maptype == ASIS) {
    curr->next = curr;
}
   else if (maptype == IDEAL) {
      logorg_mapideal(logorgs[logorgno], curr);
   }
   else if (maptype == RANDOM) {
      logorg_maprandom(logorgs[logorgno], curr);
   }
   else if (maptype == STRIPED) {
      numreqs = logorg_mapstriped(logorgs[logorgno], curr);
   } else {
      fprintf(stderr, "Unknown maptype in use at logorg_maprequest -
%d\n", maptype);
      exit(1);
   }

   if (reduntype == NO_REDUN) {
   }
   else if (reduntype == SHADOWED) {
      numreqs = logorg_shadowed(logorgs[logorgno], curr, numreqs);
   }
   else if (reduntype == PARITY_DISK) {
      numreqs = logorg_parity_disk(logorgs[logorgno], curr, numreqs);
   }
   else if (reduntype == PARITY_ROTATED) {
      numreqs = logorg_parity_rotate(logorgs[logorgno], curr, numreqs);
   }
   else if (reduntype == PARITY_TABLE) {
      numreqs = logorg_parity_table(logorgs[logorgno], curr, numreqs);
   }
   else {
      fprintf(stderr, "Unknown reduntype in use at logorg_maprequest -
%d\n", reduntype);
      exit(1);
   }


my question is that :
the variable( "   reduntype == PARITY_TABLE ")in debugging is not
equal to  that ("disksim_logorg org0 { Redundancy scheme =
Parity_rotated")in synthraid5.parv

thank you for your help
