You can use a shared NSS data pool and volume in a mixed cluster configuration by using Novell Cluster Services for Linux if all nodes in the cluster support the same NSS media format.
For information about upgrading to the latest media format, see Section 4.1, Guidelines for Upgrading the Media Format of NSS Volumes.
For information about converting clusters from NetWare to OES 2 SP1 (or later) Linux, see the OES 2 SP3: Novell Cluster Services NetWare to Linux Conversion Guide.
