Failed disk shred operation results in a disk with no label

The disk shred operation destroys the label for the disk and recreates the label. If the shred operation aborts in the middle or the system crashes, the disk might go in an error state with no label.

  2. Start the shred operation. If the disk shows as a non-VxVM disk, reinitialize the disk with the vxdisksetup command in step 1, then restart the shred operation.
    # /etc/vx/bin/vxdiskunsetup [-Cf] -o shred[=1|3|7] disk...
