Managers,
I just saw a marketing presentation about Tru64 / SANs.
One of the slides read:
====
Gaining Productivity with SAN Initiated Backup
* Enterprise Volume Manager V2
- Full support for Tru64 UNIX and TruCluster Server V5 for controller-based snapshot/clone generation
* AdvFS provides Freeze/Thaw to enable consistent clone or snapshot
* LSM supports cloned volumes
====
Does anyone know what they are talking about with "AdvFS provides Freeze/Thaw ...."
Is it useful in a standalone server, or only with a cluster where you are running the CFS.
Are there command line tools available to invoke this behavior?
If not, a C-callable API?
Is this only available when you buy EVM V2, or is provided one of the Tru64, TruClusters, AdvFS licenses?
PS: I am familiar with quiesing an application prior to making a snapshot, but this sounds like something that may be needed in addition to that in a CFS environment with direct_io in use.
Thanks
