Thanks.
But I have the problem that the node don't boot after I extend the rootvg
over 2 disks.

The problem is this:

I migrate a SP node from AIX 4.3.3 to AIX 5.2. The first migration fails,
because hd5 was only 8 MB and the procedure can't extend hd5 because hdisk0
was full. So I reboot the node normal and extend the rootvg with the second
disk and mirror to hdisk2 and hdisk3. Then I extend hd5, it is located
complet on hdisk0, start an bosboot -ad /dev/hdisk0.
Now I restart the migration and it runs. But after the migration the node
reboots automatically (this is o.k.), but it stops by starting the AIX.....
I start the node in maintenance mode and check rootvg, but it shows o.k. I
controll with lslpp the software and it is on AIX 5.2 and PSSP 3.5

that's my problem

I don't think there's any particular limit to how many disks rootvg is on.
Four is certainly OK.

In general, it is advisable to keep application data out of rootvg: it
makes
life simpler in the long run. You might want to see if you could create a
new VG instead and move some stuff into that.
