It turns out there is no official support to NetApp MPIO during a DVD BOS Install. I've opened a support case at IBM and they confirmed it.
I was able though, to work around it using 'non-official' ways.
First, start the installation processing booting from the DVD.
At the "Welcome to Base Operating System" menu, choose "3 Start Maintenance Mode for System Recovery" :
3 Start Maintenance Mode for System Recovery
Then in the 'Maintenance' Menu Select "3 Access Advanced Maintenance Functions":
3 Access Advanced Maintenance Functions
There, remove all disks (paths), with the exception of one, which will be used to be migrated/installed. You can use the following script to remove the disks:
disk=hdisk0
for pv in $(lspv | grep -v "$disk " | cut -d ' ' -f1)
do
rmdev -dl $pv
done
exit # Going Back the Migration Menu
This solves the first PVID problem, so after you are back to the migration menu, go back to the installation options and start the migration.
Finally, the Migration will continue and all packages will be installed. But there will be another issue at the very end. At the point when the boot section will be installed in the disk, the duplicated disks will be back, and this step will fail. But I was able to install it myself with the following steps:
disk=hdisk0 #The Migrated/installed PV
for pv in $(lspv | grep -v "$disk " | cut -d ' ' -f1)
do
rmdev -dl $pv
done
importvg -Oy rootvg $disk
mount /usr
/etc/methods/cfg64
ln -fs /usr/lib/boot/unix_64 /unix
ln -fs /usr/lib/boot/unix_64 /usr/lib/boot/unix
mkboot -cd/dev/$disk
cp -rp /usr/lpp/bos/inst_root/etc/rc.teboot /etc/rc.teboot
cp -rp /usr/lpp/bos/inst_root/sbin/rc.boot /sbin/rc.boot
bosboot -ad /dev/$disk
Hope this helps someone in trouble like I was
