Removing duplicate devices from vxdisk list

I replaced a disk in one of our A5200s sometime back, and noticed that vxdisk was displaying two entries for the device once I replaced it with vxdiskadm:
$ vxdisk list

DEVICE       TYPE      DISK         GROUP        STATUS
c7t21d0s2    sliced    disk01       oradg        online
c7t22d0s2    sliced    disk02       oradg        error
c7t22d0s2    sliced    -            -            error
c7t23d0s2    sliced    disk03       oradg        online

To fix this annoyance, I first removed the disk disk02 from the oradg disk group:
$ vxdg -g oradg rmdisk disk02
Once the disk was removed, I ran vxdisk “remove” two times to remove both disk access records:
$ vxdisk rm c7t22d0s2
$ vxdisk rm c7t22d0s2
After both device access records were removed, I executed ‘devfsadm -C’ to clean the Solaris device tree, and then ran ‘vxdctl enable’ to have Veritas update the list of devices it knows about. After these operations completed, the device showed up once in the vxdisk output:
$ vxdisk list

DEVICE       TYPE      DISK         GROUP        STATUS
c7t21d0s2    sliced    disk01       oradg        online
c7t22d0s2    sliced    disk02       oradg        online
c7t23d0s2    sliced    disk03       oradg        online

I have seen times where the Solaris device tree will hold on to old entries, which unfortunately requires a reboot to fix. Luckily for me, this wasn’t the case with my system.
