Want to remove backupd04    c7t2d10s2 from the volume below (backupvol).
It is in the diskgroup, but not being used in the volume.

If I do a:

vxdg -g backupdg -k rmdisk  backupd04

Will that mess up my volume?

if the disk is not being used by the volume then you can remove it from the diskgroup by
 
# vxdg -g <disk_group> rmdisk <disk_name>
 
but if it is being used by a volume then
 
first you will need to evacuate the volume onto another disk and then you can remove it from the diskgroup..
 
this can be done online using
 
# vxevac
 
or
 
# vxdiskadm option 7
