Unmanaged Zoned SAN goes offline after update
Symptom–After an unmanaged SAN is updated with a new zone, it goes offline and never returns.
Possible cause–The syntax of XML and/or entries may be unexpected.
Suggested action–Edit the unmanaged SAN XML file for the offline network and verify that all XML
content is correct, including the format of the XML and the opening and closing characters for XML
entries. Checking the SPM log file may also be helpful in this situation. For more information, see
“XML file lifecycle” (page 92)
