AIX mount points (SAN)

UNIX AIX
1

I have a mount point that I would like to have RW on one server and RO on 2 other servers. The issue that I have is that it does not seem to update on the RO servers when I make changes on the server that is RW.
Lets say I have /oracle/clone mounted RW on serverA. I am able to mount /oracle/clone on serverB and serverC as RO. I create a file on serverA and it does not show up on the other servers unless I umount it and re-mount it.

Has anyone else seen this before or have any other ideas or a better solution?

Thanks

It is better to use NFS in this situation.. Have you considered this option?

I mentioned it but it was setup this way prior to me taking over.
I may try to reinforce my opinion on it this way instead.

Thanks
