The following enhancements and changes for OES 11 and later can impact your BCC upgrade from OES 2 SP3:
EVMS was deprecated: The Enterprise Volume Management System (EVMS) was deprecated beginning in SLES 11 and in OES 11.
NLVM: The Novell Storage Services (NSS) management tools were modified to use Novell Linux Volume Manager (NLVM) as the storage manager. For information about using NLVM commands, see the OES 11 SP1: NLVM Reference.
NSS support for GPT: NSS management tools were modified to support both DOS and GPT device formats on OES 11 and later clusters.
NSS support for partitions up to 8 TB: NSS was modified to support partitions up to 8 TB in size on OES 11 and later clusters. Partitions of 2 TB and larger are formatted as GPT. Previously, partitions were limited to up to 2 TB.
CSM compatibility mode: In OES 11 and later, Novell Cluster Services was modified to support EVMS Cluster Segment Manager (CSM) only in compatibility mode. You can use CSM-based cluster resources on OES 11 and later clusters, but you cannot create new CSM-based Linux POSIX cluster resources.
Clustered LVM volumes: In OES 11 and later, Novell Cluster Services was modified to support clustering Linux Logical Volume Manager (LVM) volume groups and volumes.
