afd_unlabel does not work

Hi,

Before install grid, i used asmcmd afd_label to label some disks. But during the installation the installer cannot find this disks and reported 'Error 49802 initializing ADR'. I tried to change the disk string, but still cannot find any disks.

Now i want to re-start grid installer and don't want to use AFD. I used asmcmd afd_unlabel to remove this labels. e.g.

[root@node19c1 bin]# ./asmcmd afd_unlabel DATA1

[root@node19c1 bin]# ./asmcmd afd_unlabel /dev/xvdg1

The commands run with no error.

Then i reboot system.

Then i used afd_lslbl and see the labels are still there!
