Just check for the following
fir determine the volume group of the disk. login as root and type lsvg
this will output all the VGs in your system
then do lsvg -p vgname for all vgs in your system till you get the faulty pv name
then do a lspv -l hdiskx where x is the number for faulty drive . now move all the data from faulty pv using migratepv command. remove the disk from vg using reducevg vgname hdiskx
then you can safely remove the faulty drive

Follow the below steps,

Before doing this know the VG of that PV by using- lspv <pvname> command

1) First unmirror the VG: unmirrorvg <vgname>
2) Reduce the PV from the VG: reducevg vgname pvname
3) clear the boot record: chpv -c <pvname>
4) Remove the disk definition from ODM: rmdev -dl <pvname>
5) Finally, remove the failed hard disk/PV manually from the server.

I hope this helps you.

Hello,

I suggest to you, to use the diag tool, in order to replace a failed PV.
Once your disk is removed from your VG, use smitty diag and use the hot plug task to remove the failed disk and regonize the new one.
