Operating Systems AIX Upgrading from native MPIO to SDDPCM AIX 6.1 Post 302513831 by Omaran on Thursday 14th of April 2011 07:00:27 AM
I went through this a while ago, if I remember correctly you can just install sddpcm and then reboot. The above commands you have posted are if you are upgrading sddpcm to another OS release - if you have a test lpar you could try it?

If not it won't hurt to do the above method, this is what I have done recently after upgrading from AIX 6.1 to 7.1 - I didn't do step 6 though, it's just easier to reboot Smilie

Don't forget to install the host attachment fileset for your relevent storage as well, the disks will look like this after (this is DS8000)

hdisk2 Available 09-08-02 IBM MPIO FC 2107
hdisk3 Available 09-08-02 IBM MPIO FC 2107
hdisk4 Available 09-08-02 IBM MPIO FC 2107
hdisk5 Available 09-08-02 IBM MPIO FC 2107
hdisk6 Available 09-08-02 IBM MPIO FC 2107
hdisk7 Available 09-08-02 IBM MPIO FC 2107

When all done you should be able to run the pcmpath query adapter command
