Novell NetWare 6.5 Support Pack 6
Novell Cluster Services 1.8
After upgrading Novell Open Enterprise Server Support Pack 2 (NetWare based) or Novell NetWare 6.5 Support Pack 5 to Support Pack 6 all partitions available over iSCSI or a Fiber Channel lost their "Shareable for Clustering" flag.
When trying to re-flag the partitions using F6 in NSSMU after a warning message a "20896 cluster sharing violation" error appears.
The cluster itself is manageable, but no partitions can be expanded.
The actual issue is the flag "Shareable for Clustering" is set, but not visible.
A new MM.NLM, dated November 17th 2006, or later solves this.
Found in MM65SP6.EXE patch.
