About <strong>Veritas</strong> <strong>Storage</strong> <strong>Foundation</strong> <strong>and</strong> <strong>High</strong> <strong>Availability</strong> <strong>Solutions</strong>Known issues75Replication hang when VVR logowner is on CVM slave node (2405943)When VVR is used for asynchronous replication in shared disk group environment,one of the nodes of the cluster at the primary site is chosen as the logowner. Whenthe logowner node is on a node which is a slave node for the underlying CVMcluster, in the presence of heavy I/O from a node that is not the logowner, it ispossible to get into a replication hang. This is due to an internal defect which willbe fixed in later releases.Workaround:Enable the PreOnline trigger of the RVGLogOwner agent so that the VVR logownerwill always reside on the CVM master node. For the detailed procedure, refer tothe RVGLogowner agent notes section in the <strong>Veritas</strong> Cluster Server Bundled AgentsReference Guide.vradmin verifydata may report differences in a cross-endian environment(2834424)When replicating between two nodes in a cross-platform environment, <strong>and</strong>performing an autosync or replication, the vradmin verifydata comm<strong>and</strong> mayreport differences. This is due to different endianness between the platforms.However, the file system on the secondary node will be consistent <strong>and</strong> up to date.vradmin verifydata operation fails if the RVG contains a volume set(2808902)In a VVR environment, the vradmin verifydata comm<strong>and</strong> fails with the followingerror if the replicated volume group (RVG) contains any volume set:Message from Primary:VxVM VVR vxrsync ERROR V-5-52-2009 Could not open device/dev/vx/dsk/vvrdg/ due to: stat of raw character volume pathfailedvradmin repstatus operation may display configuration error after clusterreconfiguration in a CVR environment (2779580)In a CVR environment, if there is a cluster reconfiguration, the vradmin repstatuscomm<strong>and</strong> may display the following error message:No Primary RVGThe vradmin repstatus comm<strong>and</strong> functions normally on the Primary site.Workaround:Restart the vradmind daemon on both the Primary <strong>and</strong> Secondary nodes.
