The example below is showing duplicate entries in vxdisk list along with an error status:

# vxdisk list

However, vxprint -ht -g testdg shows that the testvol volume is ENABLED and ACTIVE:

Data on the disks remains accessible through VERITAS Volume Manager (VxVM) and the mounted file system. Therefore, vxdisk list displays incorrect information regarding the duplicate entries, and being in an error status.
 

Solution 1:

With Storage Foundation 5.0 MP3, and above the following commands can be tried first without restarting vxconfigd:

# rm /etc/vx/disk.info
# rm /dev/vx/dmp/*
# rm /dev/vx/rdmp/*
# vxddladm -c assign names


Solution2:

With any version prior to 5.0 MP3 where the disk.info file exists, vxconfigd must be restarted in order to recreate the dmp nodes, and the disk.info file.
IMPORTANT: If this is part of a VCS cluster, freeze all service groups before running these commands.

# rm /etc/vx/disk.info
# rm /dev/vx/dmp/*
# rm /dev/vx/rdmp/*

# vxconfigd -k


# vxdisk list
