Informix Software Mirroring

I experienced a disk medial failire on my disks that has the rootdbs dbspaces. I had two instances set up on these partitions. I had Informix software mirroring configured so I still have one of my instances on line. Can anyone lend some advice as to the best approach to be used in replacing the bad disk that had my rootdbs. If I was to bring down the instance and reinitialize, will I encounter problems by the fact that my rootdbs primary chunk is down? or will it just transparently get the system related information from the mirrored rootdbs.

The engine is just complaining that the primary chunk is down but running off the mirror. If that's true you can use onmonitor or onspaces to replace the down chunk with another or shutdown, dd the mirror chunk to a new chunk and link it to the original chunk path/link. Then restart the engine. Oh, and I HOPE you do not mean 'initialize' as in oninit -i, that will wipe you out altogether! Don't do that. Art S.
