VxVM vxdisk ERROR V-5-1-16081 Device has a UFS FS on it
Vxdisksetup in version 5.1SP1 does an additional check for possible UFS filesystems so as not to inadvertently destroy any UFS filesystem when reinitializing the disk. This would more commonly be associated with boot disks, but it is equally possible for UFS filesystems to be used with Volume Manager where the disk is not associated with booting of a system.
There are two possible ways to solve the issue.
Use the undocumented '-r' option (introduced in SF 5.1SP1)
For sliced disk,
# /etc/vx/bin/vxdisksetup -ir
or for cdsdisk (default)
# /etc/vx/bin/vxdisksetup -ir
Second option (not recommended as is can be destructive if not used with care) is to remove the old partition with UFS filesystem, using 'dd' command and rescan the device tree..
# dd if=/dev/zero of=/dev/vx/rdmp/
# vxdctl enable
