Current FC tries to limit the scanning range by detecting the target and
channel, unfortunately this code has a good number of implementation
issues:
- Matching uses local WWNN instead of target's WWPN.
- Not using a shell to run the command, so the * glob won't expand.
- Not using -l on grep command to list file names instead of contents.
- Not making the search case insensitive.
This patch fixes all these issues by using the target's WWPNs instead
-taking into account FC Zone/Access control information if present- and
supporting both possible connection information formats for the WWPNs
(single value or list of values).
Rescan tests have been modified to adhere to unit tests best practices,
where each test case only tests the specific code in the method under
test and mocks everything else.
