Description of problem:
It's not possible to add fence_scsi as a stonith device in pacemaker:
# pcs stonith describe fence_scsi
Stonith options for: fence_scsi
Traceback (most recent call last):
  File "/usr/sbin/pcs", line 110, in <module>
    main(sys.argv[1:])
  File "/usr/sbin/pcs", line 96, in main
    stonith.stonith_cmd(argv)

    stonith_list_options(argv[0])

    dom = parseString(metadata)

    return expatbuilder.parseString(string)
  File "/usr/lib64/python2.6/site-packages/_xmlplus/dom/expatbuilder.py", line 942, in parseString

    parser.Parse(string, True)
xml.parsers.expat.ExpatError: mismatched tag: line 20, column 3

The same error repeats when you do pcs stonith create.

I'd also like to raise a question how unfencing should be done with pacemaker and fence_scsi. In cluster.conf we had <unfence> tags for this. I'm unable to find any useful pointer to how this is handled in pacemaker cluster.

Version-Release number of selected component (if applicable):
fence-agents-3.1.5-31.el6.x86_64
pcs-0.9.59-1.el6.noarch

How reproducible:
always

Steps to Reproduce:
1. pcs stonith describe fence_scsi
2.
3.

Actual results:
traceback

Expected results:
no traceback on any valid operation (describe, create among others)
