Symptom

Following an operating system crash or the installation of an operating system patch, IBM Informix Storage Manager (ISM) fails to start and the following error appears in the daemon.log:


09/02/02 07:38:18 nsrd: server notice: started
09/02/02 07:38:19 nsrexecd: Can’t initialize

                   file /nsr/res/nsrla.res already
                   in use; check for another copy of
                   this server already running

09/02/02 07:38:19 nsrd: successful shutdown

Cause

Corruption in the INFORMIX Storage Manager (ISM) nsrmmdbd database causes the WISS error.

The following situations can cause corruption in the ISM nsrmmdbd database:

1. ISM process exits without shutting down properly.
2. Power failure to unprotected systems.
3. Hardware failure.
4. Disk crash.
5. Installing an operating system (OS) patch.

Resolving The Problem

Perform the following steps as root to re-build the nsrmmdbd database:

WARNING

Storage volume(s) needs to re-label and mount on appropriate device after run the ‘nsrck’ command. When re-label a volume, the original data can no longer recoverable.
