Resolution
This issue can be identified when "vxdisk -e list" is executed.
The disk showing up in the list as a device as well as being a multipathed device (Disk_3) is an indication that this is an incorrect entry.
The solution is to physically remove the device node entries, clean and rebuild the device tree at the OS level and have Volume Manager rescan the devices.
1. Remove all affected devices from VM
Example:
2. Remove the device nodes for the affected device(s).
Note: If device is a CTD pathname, omit the s2 from the device name.
Example:
3. Clean out the device tree and have VM scan for devices
4. Run a disk list again to see if the entries have reappeared.
