I'm new in the AIX-environment. Right now i'm testing some stuff out. But i can't test the LVM-part which is (to me) very important. I have 2 disks in my testmachine but it seems only 1 is working wel. I'll show you the output below of the disks...
hdisk0 = in good condition
hdisk2 = broke???

when trying to make a vg and include this disk:
# mkvg testvg hdisk2
0516-306 mkvg: Unable to find physical volume testvg in the Device
Configuration Database.

Is this disk really broke? Is it really the disk?
thanks for replying!
