Then when I check the file sets -  5.1 is now broken.

I tried to force overwrite the 5.1.0.0, that does not work.  It seems like its busy, but in the docs, they mention it can be upgraded from PP 4.5 on up.  I know if I uninstall everything that would work, but won't work for us. It has to be upgraded.  We would need a major outage to do the removal.

1.are you booting from SAN ?

2. are you sure that your VG was successfully varied off??

These are not SAN boot.  No I didn't veryoff any VG.  We were told we could just upgrade these filesets without doing any of that.

Pretty much we were told to update the ODM, then update PP, reboot.  Thats it as long as the OS versions were met.

Man , I have few comments here;

1. If you are running AIX 5.2 and EMC ODM Package 5.0.0.0 or 5.0.0.1,you must remove them before installing this version.
If you are running EMC ODM package 5.1.0.0 or 5.2.0.0 and higher, then proceed with the upgrade. read the readme carefully first :

ftp://ftp.emc.com/pub/elab/aix/ODM_DEFINITIONS/archive/README.5301

2. Step A in the PP upgrade is to close all applications that use PP devices, and vary off all volume groups except the root volume group (rootvg) !

check this emc144935

Thanks for answering.  I'll test that.

We just had this very same problem.  I opened an SR with EMC Support.  They told me to uninstall and re-install PowerPath.  Here are the commands, completely described in the PowerPath Manual:

installp -u EMCpower

installp -agXd . EMCpower

And that fixed us up!
