RE: Disk Crash

Roger, If your down chunk is mirrored, you should be able to recover it to the new chunk using onspaces or onmonitor (onmonitor is not recommended, but easier). The general syntax for onspaces is: Onspaces -s dbspacename -p pathname -o chunk_offset -O The last item is a capital O, not a zero, I believe. --EEM > -----Original Message----- > From: Neil Truby [mailto:neil.truby@ardenta.com] > Sent: Monday, September 20, 2004 4:27 PM > To: informix-list@iiug.org > Subject: Re: Disk Crash > > Er, am I missing something? > You had a link to a chunk on disk A. > Disk A failed. > So you changed the link to point to a completely unconnected chunk on disk > B. > Now you're wondering why the data that used to be on disk A isn't by magic > now on disk B just because you retrospectively switched a symlink. > > I am missing something, aren't I ...? > > "Roger Cariah" <rogerc@ppsl.co.tt> wrote in message > news:cinbm3$n9g$1@news.xmission.com... > > > > > > Hi, > > > > One of my physical disk that had the roodbs critical chunk crashed.
