Comment 2 for bug 1013724

multipath.conf follows. The file is heavily commented so I trimmed all comments out

defaults {
 user_friendly_names yes
}
blacklist {
 devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[-1-9]*"
 devnode "^hd[a-z][[0-9]*]"
 wwid 3600508b1001cea3b91ee45c710e467a7 #sda
 devnode "sr0"
}

devices {
 device {
  vendor "HITACHI "
  product "DF600F.*"
  no_path_retry queue
  prio const
  path_grouping_policy multibus
  getuid_callout "/lib/udev/scsi_id --whitelisted --device=/dev/%n"
  checker tur
 }
}

Here's the _full_ output of multipath -ll
# multipath -ll
Error: : Inappropriate ioctl for device
cciss TUR failed in CCISS_GETLUNINFO: Inappropriate ioctl for device <----

I cannot flush even when the multipath and iscsi daemon are stopped.
