Recovering a version 0 DCO volume
To recover a version 0 DCO volume
1
Correct the problem that caused the I/O failure.
2
Use the following command to remove the badlog flag from the DCO:
# vxdco [-g diskgroup] -o force enable dco_name
For the example output, the command would take this form:
# vxdco -g mydg -o force enable vol1_dco
The entry for vol1_dco in the output from vxprint now looks like this:
dc vol1_dco vol1 - - - -
3
Restart the DCO volume using the following command:
# vxvol [-g diskgroup] start dco_log_vol
For the example output, the command would take this form:
# vxvol -g mydg start vol1_dcl
