After restoring a system, using the mksysb command, the ricdiag diagnostic utility can fail, returning an error code ric0428.
This is because, after running mksysb, the file dgr0d31014d.00.00 is missing from /usr/lib/microcode. This file is used by the ricdiag command and must be present.
Resolving the problem
Either copy the file from another Blueworx Voice Response system, or reinstall the DTXA or DTTA driver from /usr/lpp/dirTalk/devices/dtqa_bin directory. Once the file has been restored, check that ownership is set to bin:bin, and permissions are set to -r-xr-xr-x. Then restart Blueworx Voice Response.
