+* How to add new LUNs to Bytemark Cluster
+
+{{{
+  + Add a new LUN in the MSA and export it to all blades
+
+  then:
+  gnt-cluster command "echo 1 > /sys/bus/pci/devices/0000:0e:00.0/cciss0/rescan"
+  
+  then:
+  reload multipath-tools on gnt-master (normaly bm-bl1):
+  /etc/init.d/multipath-tools reload
+  add the WWNs to dsa-puppet/modules/multipath/files/bm-multipath.conf and define the alias and commit that file to git.
+
+  then:
+  gnt-cluster command "puppet agent -t"
+
+  This will update the multipath config on all cluster nodes. WITHOUT doing this, you can't migrate VMs between nodes.
