Configuration example:
- EVA 6000
- SRV1 Windows 2003 mount on X: a vdisk (vdisk0 for example)
- SRV1 share X: (file server)
Question: when I create a snapshot of vdisk0 using CV graphical interface, how can I be sure that the Windows cache is flushed on disk before the snapshot execution ?
I can change the cache mode of the vdisk0 (WRITETHROUGH), but I think that this operation only flushes the data of the EVA controllers.
Thanks for help
Armando

Re: EVA + Windows + host cache flush
The Replication Solutions Manager (RSM, which is licensed with the BC-EVA or CA-EVA license) has a host agent and the necessary means (function call) to tell the host to flush the file system.

Re: EVA + Windows + host cache flush
You can get the EVA VSS Providers here: http://h18004.www1.hp.com/products/storageworks/vdsvsshard/index.html?jumpid=reg_R1002_USEN
With these, you can use the standard Windows Volume Shadow Copy service to create BC snapshots.
Good luck,
Vince
