If VxVM has marked a disk with the udid_mismatch flag or the clone_disk flag, you can update the stored UDID for the disk. This procedure uses the current value of the UDID that is stored in the Device Discovery Layer (DDL) database to correct the value in the private region. Use this option any time you do not need to maintain the distinction between clone disks and the original disks. For example, if the disk is not really a clone or if you are using the entire set of clone disks on a separate host.
To update the UDID for a disk
# vxdisk [-cf] [-g diskgroup ] updateudid disk ...
For example, the following command updates the UDIDs for the disks sdg and sdh:
# vxdisk updateudid sdg sdh
The -f option must be specified if VxVM has not set the udid_mismatch flag for a disk.
If VxVM has set the udid_mismatch flag on a disk that is not a clone, specify the -c option to remove the udid_mismatch flag and the clone flag.
