Environment

Novell NetWare 6.5 with SP5 in a Cluster using a HP SAN and SecurePath

Situation

One node in the cluster could see all the pools just fine, but the other nodes could not see certain pools. Partfix on these other servers reported the error: "ERROR: Partition size exceed device capacity".

Resolution

This error message often indicates that a driver has been changed which reports the drive capacity differently. In this case the CPQSHD.CDM and QL2300.HAM drivers were consistent on all nodes. The problem turned out to be a difference with the Secure path HPQSP.CDM modules. The servers that did not see the capacity properly was running version 0.10.25 dated January 14, 2004. While the server that was working was running version 0.11.25 dated June 30, 2004. Make sure all nodes are running the current release of this module.
