Title: Host iSCSI Discover Action
Describe the issue:
1. iscsidiscover action provides a list of iSCSI targets, hence, all occurrences of 'list of LUNs' should be changed to 'list of targets'.
2. in the example, 'port' tag is unclosed; i.e. s/<port>3260<port>/<port>3260</port>
Suggestions for improvement:
Checked throughout the guide for missing / in closing tags.
