UT:

1. default restart local res

[root@yanlidev1 examples]# lsgrun -m "yanlidev1" ps -ef | grep c101 | grep res
root      5167  5158  0 Sep04 ?        00:00:00 /scratch/lsf101/c101/10.1/linux3.10-glibc2.17-x86_64/etc/mgres
root      5852     1  0 01:04 ?        00:00:00 /scratch/lsf101/c101/10.1/linux3.10-glibc2.17-x86_64/etc/res
root      6937  5852  0 01:05 ?        00:00:00 /scratch/lsf101/c101/10.1/linux3.10-glibc2.17-x86_64/etc/res
[root@yanlidev1 examples]# python restartRES.py
res on yanlidev1.fyre.ibm.com restarted
[root@yanlidev1 examples]# lsgrun -m "yanlidev1" ps -ef | grep c101 | grep res
root      5167  5158  0 Sep04 ?        00:00:00 /scratch/lsf101/c101/10.1/linux3.10-glibc2.17-x86_64/etc/mgres
root      7125     1  0 01:05 ?        00:00:00 /scratch/lsf101/c101/10.1/linux3.10-glibc2.17-x86_64/etc/res
root      7177  7125  0 01:05 ?        00:00:00 /scratch/lsf101/c101/10.1/linux3.10-glibc2.17-x86_64/etc/res

2. specify 1 host

[root@yanlidev1 examples]# lsgrun -m "yanlidev1" ps -ef | grep c101 | grep res
root      5167  5158  0 Sep04 ?        00:00:00 /scratch/lsf101/c101/10.1/linux3.10-glibc2.17-x86_64/etc/mgres
root      7125     1  0 01:05 ?        00:00:00 /scratch/lsf101/c101/10.1/linux3.10-glibc2.17-x86_64/etc/res
root      7177  7125  0 01:05 ?        00:00:00 /scratch/lsf101/c101/10.1/linux3.10-glibc2.17-x86_64/etc/res
[root@yanlidev1 examples]# python restartRES.py yanlidev1
res on yanlidev1 restarted
[root@yanlidev1 examples]# lsgrun -m "yanlidev1" ps -ef | grep c101 | grep res
root      5167  5158  0 Sep04 ?        00:00:00 /scratch/lsf101/c101/10.1/linux3.10-glibc2.17-x86_64/etc/mgres
root      7488     1  0 01:05 ?        00:00:00 /scratch/lsf101/c101/10.1/linux3.10-glibc2.17-x86_64/etc/res

3. specify 2 hosts

[root@yanlidev1 examples]# lsgrun -m "yanlidev1 malpha1" ps -ef | grep c101 | grep res
root      5167  5158  0 Sep04 ?        00:00:00 /scratch/lsf101/c101/10.1/linux3.10-glibc2.17-x86_64/etc/mgres

[root@yanlidev1 examples]# python restartRES.py yanlidev1 malpha1
res on yanlidev1 restarted
res on malpha1 restarted
[root@yanlidev1 examples]# lsgrun -m "yanlidev1 malpha1" ps -ef | grep c101 | grep res
root      5167  5158  0 Sep04 ?        00:00:00 /scratch/lsf101/c101/10.1/linux3.10-glibc2.17-x86_64/etc/mgres
