I'm afraid the "11.6.2 Removing the Shadow Volume Relationship" instructions do not/cannot work....

a) If you mount the volumes separately, as per "In NSSMU or iManager, activate the shared pools and mount the two volumes." then it is impossible to see the File System Shadow Path under (i) on the primary volume in NRM

b) If you mount as shadow pair, the UNMOUNT ( then you no longer see the volume in NRM Manage Shares page, so it is impossible to access the "Remove Shadow Action Options"

So, how are you supposed to remove a cluster based shadow?
