Re: Setting up Rootdbs on a raw disk

It could be a typo, but in your onconfig file the file is /dbdisks/rootdbs and you have created the link as /dbdisk/rootdisk. Is it right. Another question - have you created the mirror device file (/dbdisks/mirrorroot)? And the last question - have you changed the ownership/group of files to informix:informix and the permissions to 660 on the link AND on the device special file ?
