Disaster recovery plan for ClearCase

I have been asked to create DR plan for Clearcase. I have the vobs backed up to the DR Server. What else would I need for DR?

Thanks

Solution

  • The kind of DR infrastructure that I had to manage involved also an SDRF mechanism in place in order to have a rela-time synchronization of the server content.
    The idea of a DR is that it can take place at any time. Restarting the service in the other server wasn't enough. A quick checkdb was also required.

    The other aspect was about keeping the same server name (even if its physical server changes), which means updating the DNS servers quickly enough for a client to be able to contact the new ClearCase server.

    I didn't have to deal with the view server (each client was its own view server)

    A separate license server was also in place on the DR server (since the hostid differs, you need to reserve a few licenses for working during a DR with IBM Rational products).
