Description

launching sanity.sh in Xeon Phi I encountered with following issues that can be fixed by changing test scripts:

1. Xeon Phi don't support "mount -t lustre", we can use only "mount.lustre"
2. A "head" utility don't support shortcut "-1" option. It should be specified as "-n 1".
3. A "sed" utility don't support expression "s/[-.]/ /3"
