I reinserted it but I don't find how to restore correct usage.<BR />Under vxdiskadm,<BR />4. Replace disk seems to refuse to work if source and target disk are the same<BR />I tried 3. Remove disk for replacement and 3. Remove disk but I am still unable to perform 4 and restore the normal vxdisk list output.<BR />I also tried 1. Initialize but it seems to consider the disk is still part of the disk group and fails.
