There was no LUNs before, multipathd was stopped and multipath.conf inexisted. I was able to log in and manually configure multipath.conf, a simple multipathd start was not enough.</div><div style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;" data-mce-style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;"><br data-mce-bogus="1"></div><div style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;" data-mce-style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;">If this wasn't enough, my double NetAPP ( through an Hitachi ) provided me with a not so empty brand new LUN, and the task to add the FCP failed to point this. Trusting my double, I spent some precious time searching for different problems, until receiving some guidance and do a simple dd if=/dev/zero to the initial blocks of the LUN.</div><div style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;" data-mce-style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;"><br data-mce-bogus="1"></div><div style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;" data-mce-style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;">Consulting the documentation ( http://www.ovirt.org/OVirt_Administration_Guide#Adding_FCP_Storage ) for this matters, was not of any help.</div><div style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;" data-mce-style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;"><br data-mce-bogus="1"></div><div style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;" data-mce-style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;">So, my questions:</div><div style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;" data-mce-style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;"><br data-mce-bogus="1"></div><div style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;" data-mce-style="font-family: lucida console,sans-serif; font-size: 12pt; color: #000000;">This is the intended behavior?
