Check if a hardware failure or administrator action has accidentally damaged the device specified as the DMTLOGDEV in the DM_LOCAL_DOMAINS section of the BDMCONFIG file. If possible, repair any corruption. If the DMTLOGDEV must be recreated, shut down the Domain gateway group. Then use the dmadmin(1) subcommand crdmlog to create the domain, or just reboot the Domain gateway group, which will automatically create the log if it does not already exist.
