108Veritas Cluster Server support for using CVM with multiple nodes in a Oracle VM Server for SPARC environmentCluster Volume Manager in the control domain for providing high availabilityNote: The ability to take online snapshots is currently inhibited because the filesystem in the guest cannot coordinate with the VxVM drivers in the controldomain.Make sure that the volume whose snapshot is being taken is closed before thesnapshot is taken.The following example procedure shows how snapshots of shared volumes areadministered in such an environment. In the example, datavol1 is a shared volumebeing used by guest domain logical domain1 and c0d1s2 is the front end for thisvolume visible from logical domain1.To take a snapshot of datavol11 Unmount any VxFS file systems that exist on c0d1s0.2 Stop and unbind logical domain1:primary# ldm stop logical domain1primary# ldm unbind logical domain1This ensures that all the file system metadata is flushed down to the backendvolume, datavol1.3 Create a snapshot of datavol1.See the Veritas Storage Foundation Administrator's Guide for information oncreating and managing third-mirror break-off snapshots.4 Once the snapshot operation is complete, rebind and restart logical domain1.primary# ldm bind logical domain1primary# ldm start logical domain15 Once logical domain1 boots, remount the VxFS file system on c0d1s0.
