Whether these are hardlinks or softlinks doesnt matter too much. I think what you are trying to cross-filesystem is softlink anyways.
Well, lets say you have two filesystems on your AIX Server called Server1
/fs1 /fs2
Lets say you have a softlink on /fs2 back to /fs1 to a file (eg) /fs2/file_from_fs1 -> /fs1/file_from_fs1
Lets assume you replicate /fs2 only. You mount a copy of /fs2 to a DR server as /fs2 on Server2
Now, the softlink is broken, as there is no /fs1 on that server. The only thing to work in that instance would be NFS shares to point back explicitly to SERVER:/fs1
Remember with links, if you loose fs1, fs2 will NOT contain your data.
The host is an AIX with CLARiiON CX splitter. Two file systems/tow volumes, we plan to replicate one but not the other. To reduce the size of the replication and application impact, I'm wondering whether the hard/soft link can help.
