iscsi trouble
What do we have today!
Netapp is awesome.... (there is always a but! and here it is!) BUT
When configuring an iscsi lun on CentOS we change first of all the initiator name:
after that we try to discover our targets
Well as you would know this end up giving you as many targets as the NetApp filer has interfaces! (pretty much the same lun on all VLANS), which you cant access because you only have 2 NICs (one for the LAN and one for the storage LAN... and in the end of the day thats all you need! Anyway... so we add the interface
and change the configuration
That is not enough though... the discovered targets are set to automatic already... soooo lets make them all to manual:
and make the one we want automatic (so it doesnt take 100mins to start iscsi :P)
Now restart iscsi and presto!
Wooohoo! Victory!
Many thanks to Pete for helping out with this :)
