You need a backup file to recover from this. While a DRS restore can copy the database from a subscriber node (step 12) it can't get all of the platform-level details which only existed on the publisher's local disk. You'll need to build a new publisher/cluster and use BAT Export/Import to pull configuration details from the remaining subscriber, then reimport them in to your new publisher. Once your new publisher is built you can reinstall the subscriber, joining it to the new cluster.
Note that you might be able to get the database to replicate again by reusing all of the same platform details (e.g. IP, hostname, security passphrase) and then adding the subscriber under System > Servers. The problem is that the near-empty publisher database would likely overwrite the subscriber, not pull from it. Additionally, all of the shell scripts that Cisco uses to make the cluster function (it's more than just Informix) wouldn't have executed properly and you would almost certianly have other problems. The risk of totally losing your remaining data doesn't warrant this - totally unsupported - scenario.
