AIX - Can't create volume groups on new SSA disk

We've recently installed a new SSA enclosure consisting of 12 disks in two raid groups. There is a group of four 72.8 gb disks in raid 5 (hdisk74), and a group of eight 145.6 gb disks in raid 5 (hdisk73). I am trying to create a volume group and receiving errors:

mkvg -f -y TSMDBVG hdisk74
0516-1254 mkvg: Changing the PVID in the ODM.
0516-1397 mkvg: The physical volume hdisk74, will not be added to
the volume group.
0516-862 mkvg: Unable to create volume group.

I've found an IBM document covering a similar error:
http://www-01.ibm.com/support/docview.wss?uid=isg3T1010349

"Use the below command to clear the owning volume manager from the disk and then use the mkvg command again:"

chpv -C hdisk74

I've tried this and still am having the same problem.


Here's some info about the disks:

If these are new LUNs (ie there is nothing to backup or save), try the following:

chdev -l hdisk74 -a pv=clear
chdev -l hdisk74 -a pv=yes

Then re-run the "mkvg".

The first command worked but the second returned an error saying the device is busy:

chdev -l hdisk74 -a pv=yes
Method error (/usr/lib/methods/chgdisk):
        0514-062 Cannot perform the requested function because the
                 specified device is busy.

I recommend deleting and re-creating the RAID array - if that does not work, time to call IBM.
