Paging Write I/O

I opened a file for reading in cashed mode and same file in write mode for writing…I read from file and did the write. When system invoked Paging Write I/O, file object received has got only read permission, since the first file object with which cashing initiated was opened for read access.

On local file system this paging I/O Write will succeed but for remote file system, the I/O Manager of remote file system is throwing ACCESS_DENIED.
How to solve this problem for Remote File System.
