In some cases, there are customers that are morefamiliar using the vxassist option rather than vxedit option when removingvolumes. However, if a volume has an associated Data Change Object (DCO) log,the DCO log has to be removed first before you can totally remove the volumeusing vxassist option. Below you will find example which demonstrates thatprocedure.

EXAMPLE:

1. Below is a mirrored volume called "testvol"with DCO log
# vxprint -htg testdg

sddisk02-02    testvol_dcl-02 disk0243452    132      0        c1t1d0   ENA


2. Tried removing the volume "testvol" usingvxassist option, but it errors out:
# vxassist -g testdg remove volumetestvol
vxvm:vxassist: ERROR:  Cannot delete volumetestvol


3. The workaround is to remove the DCO log first, then re-runvxassist command to remove volume "testvol":
# vxassist -g testdg remove log  testvol logtype=dco
# vxprint -rhtg testdg
