MPIO Driver

On a particular LPAR, I was running AIX 5.3 TL 3. On Monday I did an update of the LPAR to 5.3 TL 9 SP2. The install was smooth, but then I ran into a problem.

The MPIO driver does not work with LSI's StoreAge (SVM4). I did some looking, and looks like

5.3 TL3 = IBM.MPIO 5.3.0.30
5.3 TL9 SP2 = IBM.MPIO 5.3.9.2

I am in the process of trying to figure out how to go back to the previous version. I searched the forum and found this link....but not sure what this will gain me.

I was thinking about recovering from the backupos I ran, as well as the file level backup from about a week ago. This should take me back to before the update....

Thoughts? Or should I just try to uninstall the MPIO package and put the older version on?
