Description

Error Message

# /usr/sbin/vxassist -g testdg mirror vol01_dcl
VxVM vxassist ERROR V-5-1-7032 volume vol01_dcl is a DCO volume. Prepare operation not allowed on DCO volume.

Cause

Resolution

The source code is modified to skip DCO log creation for DCO volume.  Fix will be included next patch on 6.0.3. through Etrack 3349498.


Applies To

RHEL6.3 / SF6.0.3
