<p>I'm writing a resource agent for handling SCST in master/slave with ALUA multipath support.<br>
On Master node it has to create a SCSI LUN mapped to a real device, and map the path as active.<br>
On Slave node (and even on Master when the resource starts) ot has to create a dummy lun (with specific null handler) in the same size of real device, and map path as standby.</p>
<p>When switching roles, it simply puts path both in standby, replaces on Master node the lun with null lun, replaces on the slave node the null lun with real device, put in active state the Slave node.<br><br></p>
