"bad primary chunk" with temporary dbspace

I'm running OnLine v7.13 on a Sun Sparc20; Solaris 2.4. I've had to restore my instance to a dump. When i bring up OnLine I see the console message Bad primary chunk '/dev/rdsk/informix_1', although this doesn't appear in the OnLine log. The log does show that my tempbds is invalid, and onstat -d shows it marked as down. A "dbspce does not exist" message is received if I try to drop the tempdbs. Informix support have told me that this is a known problem with restores including tempdbss, which can only be removed by re-initialsing and re-loading/importing. If only the tempdbs is affected I can live with it, but does anyone else have any experience of this problem? Thnaks Neil Truby Chase Bank Bournemouth, UK
