After you install or upgrade a new Veritas Volume Manager (VxVM) fileset or an Array Support Library (ASL) fileset, changes to an ASL may cause the udid_mismatch flag or the clone_disk flag to be set on disks that are not cloned disks. VxVM uses these flags to indicate hardware snapshots or copies of a LUN.
If the disk is not a cloned disk, this behavior could result in errors during disk group import, depending on the import flags. When a disk group is imported, VxVM may skip cloned disks. Also, the import may fail because a disk group has a combination of cloned and non-cloned disks.
If the disk is not a cloned disk, you must manually clear the udid_mismatch flag on the disk before the disk group import can succeed.
To clear the udid_mismatch flag from a disk
# vxdg deport dgname
Import the disk group and clear the flags for all of its disks using the -c option:
# vxdg -c import dgname
Clear the flags individually for each disk and then import the disk group:
Clear the udid_mismatch flag on all non-clone disks identified during step 1.
# vxdisk updateudid diskname
Clear the clone flag on non-clone disks.
# vxdisk set diskname clone=off
# vxdg [-cs] import dgname
Clear the flags for each disk and then import the disk group:
Clear the udid_mismatch and the clone disk flag on all non-clone disks identified during step 1.
# vxdisk -c updateudid diskname
# vxdg [-cs] import dgname
