 * How to add new LUNs to Bytemark Cluster
 
+** Add new LUN to MSA and export to all blades
+
+{{{
+  Log into MSA controller
+
+  Choose which vdisk to use, use "show vdisks" to list
+
+Add the volume:
+  # create volume vdisk msa2k-2-500gr10 size 5G donizetti      
+
+Find a free LUN:
+
+  # show lun-maps
+
+Make a note of the next free LUN
+
+Generate map commands for all blades, all ports, run locally:
+
+  $ for p in 1 2 3 4; do for bl in 1 2 3 4 5 6 ; do echo "map volume donizetti lun 27 host bm-bl$bl-p$p" ; done ; done
+
+Paste the output into the MSA shell
+
+Find the WWN by doing show host-maps and looking for the volume name.
+Transform it using the sed run at the top of /etc/multipath.conf:
+
+echo "$WWN" | sed -re 's#(.{6})(.{6})0000(.{2})(.*)#36\1000\2\3\4#'
