hte main problem is that when I use pvchange -u it refuses to make
operation to clsutered volume
Volume Groups with the clustered attribute will be inaccessible.
Found duplicate PV 46dU6F2rU9xqqOaWf8eihFwbdGp672lS: using
/dev/mapper/mpathh not /dev/mapper/mpathk
Found duplicate PV 5ZTDCmWHDH6M04nl58Wyyi3nYG8BOCRo: using
/dev/mapper/mpathl not /dev/mapper/mpathi
Skipping clustered volume group NetCluster0
0 physical volumes changed / 0 physical volumes not changed
is there a way to remove the cluster bit from the volume itself ?
thanks
Rick
