I can´t import the VG.

zeta /home/root # importvg -y vgcordb_cert hdiskpower31
0516-022 : Illegal parameter or structure value.
0516-780 importvg: Unable to import volume group from hdiskpower31.

I have this problem on the past like this with a similar CLARiiON and the way that i take i was this.

recreatevg -y vgname hdiskpowerxx hdiskpowerxx
synclvodm -v -P vgname

But in this case it´s not working. This disk´s dont have a PVID and it was difrent on the VGDA
On the hdiskpower31 it´s difrent of the other two disk. And the name of the LV have two difrnte letters.

Try with '

importvg -y 'vgcordb_cert' hdiskpower31
else try to give a major number with the vg
importvg -y 'vgcordb_cert' -V '70' hdiskpower31
Sometimes missing silly things like this AIX doesn't do what we intend to do.

Also do you have record of vgs adn pvids when you exported them, because you might be importing on wrong disk. Don't know about EMC, we have IPSTOR, so for MPIO we use dynapath, if the MPIO tool is not started, the disk doesn't allow to work on it. If you have lost your pvid, worry not, you can spoof a pvid on a disk and impirtvg, if you have records of the info. You might have to run fsck on lv after this butis much faster than restore.

Good luck
