Control File in network Share

Hi

I have split my oracle files

2 ora arch destination, on local on network share

4 group for redolog with 2 file each, on local on share

and i do that for Control File.

i have do many test, crash/restore, but if i break the share, DB dump

ORA-00221: error on write to control file

ORA-00206: error in writing (block 3, # blocks 1) of control file

ORA-00202: control file: '\\SIAE-AATWZB0\CNTRL\DVA\CNTRLDVA.DBF'

ORA-27070: async read/write failed

OSD-04016: Error queuing an asynchronous I/O request.

O/S-Error: (OS 53) The network path was not found.

if only split archive and redo, it's ok
