Answer : netware cluster data corruption need some ideas

The biggest cause of corruption on shared storage is concurrent mounting by non cluster-aware hosts. Nodes without NCS installed will be unaware that it's clustered storage. You need to be sure that anything on the back end (presume fibrechannel?) network which has access to the storage has NCS installed and correctly configured. If you have other storage and/or servers present, zone them off so things can only see what they're supposed to see.
