Dick, Welcome to the list.
Neale's already covered a couple of points, but I'll add a couple of more. The echo command into /proc/dasd/devices means that you'll be able to add/remove DASD volumes without re-IPLing your Linux/390 system. Obviously this is a very Good Thing. You say you have the SLES-7 system. Are you referring to the one that has a 2.2.16 kernel, or the 2.4 kernel? A 2.4 kernel is necessary for the dynamic capabilities I mentioned above. If it is the 2.2.16 system, then the file you need to update is in /boot, and the command will be "silo" and not "zipl" and you will have to reboot the system. If it is the 2.4 system, you also get a couple of other really nice features. One of them is that after you dasdfmt the volume, you _must_ run fdasd against it to create at least one partition. For your swap volume, that means you can create an appropriately-sized swap partition, and use the rest for data. 2.3GB for swap is overkill, to say the least. There should be a manual that you downloaded, sles7_s390_en.pdf. Take a look at that. It covers a lot of information you'll need as you go forward.

I've got the SuSE SLES-7 download system running on an LPAR, doing fine. For the installation process I did DASD in a simple manner - one 3390-3 volume for swap space, one 3390-3 volume for the complete root file system. These are using /dev/dasda and /dev/dasdb. I'm trying to figure out how to add a third volume. I haven't been able to figure out (or find) the steps to accomplish it. I can do it if I IPL the installation system from CD. I can "dasdfmt" and "mke2fs" it, and it's defined in /proc/dev/devices. But I can't get my unit associated to /dev/dasdc on my DASD-based system. (This sounds similar to Mr. Whitteridge's current issue "Adding DASD not recognized".) Can someone provide the steps, or suggest where I can find the correct manual or redbook that provides the process. Thanks!! Richard C.
