My hd5 volume is giving problem saying unable to sync the volume. For this, I unmirrored hdisk1 from rootvg and started the mirror again still gave the same problem. But now the issue is, i think mirrorvg is hanged and it is stuck at hd3 syncing. The mirrorvg seems to be hanged, can i kill the process, remove the hdisk1 from rootvg ? what can be done in this case. When I do "lslv -L hd3", it is showing 16 stale PPs since long time, kindly help in this issue.
