problem :
how can I change Storage.Misc.excCmd _getPathsStatus " /usr/bin/taskset

/usr/bin/taskset --cpu-list 0-7 /usr/sbin/dmsetup status --target

I think add iscsi type storage , if supervdsm scan mulitpah will solve
my problem .(my environment have other dm devices, use "dmsetup status"
will show them, and vdsm get dm path status will occur error )
so I changed some as follow :
（1）
I define EXT_DMSETUP_STATUS in
/usr/lib/python2.7/site-packages/vdsm/constants.py
:
/usr/lib/python2.7/site-packages/vdsm/constants.py:EXT_DMSETUP =

/usr/lib/python2.7/site-packages/vdsm/constants.py:EXT_DMSETUP_STATUS =
"/usr/sbin/dmsetup status --target multipath"
(2)
/usr/share/vdsm/storage/devicemapper.py add :
from vdsm.constants import EXT_DMSETUP_STATUS
and changed getPathsStatus cmd to " EXT_DMSETUP_STATUS" :
def _getPathsStatus():
cmd = [EXT_DMSETUP_STATUS]# before : cmd=[
EXT_DMSETUP,"status"]
Why not change this to:
cmd = [EXT_DMSETUP, "status", "--target", "multipath"]
Y.
rc, out, err = misc.execCmd(cmd)
===
but log in supervdsm log also not change . Please help me ，how to change
code to let supervdsm exec "/usr/sbin/dmsetup status --target multipath"
in function getPathsStatus（） 。
