Re: Raw devices on SUN

I'm assuming that there is no volume management in the way. df -k should give you a list of the disk and FS's on them, from this you can tell which slices on the disk can't be used. You might also like to check /etc/vfstab to make sure there are no umounted FS's lying around. prtvtoc <disk> will give you the slice details for the table. Hopefully you've got some that aren't allocated to a FS. Any of unused slices can be used for raw devices, you could use the used ones as well but the OS won't be happy:-)) If you are concerned that a FS might be on a slice that you think is unused just try and mount the slice and see if it errors Make a directory outside of the /dev system for the location of your link files, eg /chunks or ${INFORMIXDIR}/chunks etc. Then use ln -s <full path to device> <chunk name>. Make sure the permissions are informix:informix 660 on the chunkname and hopefully, unless I've forgotten something, you've got useable chunks for your instance If you are using VM then you need to use the VM software to generate the disk slices for you and this will depend on whether you are using Veritas, Disksuite etc Paul Watson WF Software Ltd Tel: +44 1436 674729 Fax: +44 1436 678729 www.wfsoftware.com # If you broke it, hide the evidence >>> "Shevkar, Mukund" <Mukund.Shevkar@dgs.ca.gov> 08/03/99 05:00PM >>> Hi list!
