Ken, As others have stated, you need to run fdasd to partition your DASD volumes. With later versions of dasdfmt, the cdl, or compatible disk layout, became the default, and ldl an option. So, unless you specify "-d ldl" on your dasdfmt command, you will need to create at least 1 partition on that volume before it can be used.
If you don't want more than one partition, you can just specify "-d ldl" on the dasdfmt command, and then you can go straight to using the volume (mke2fs, lvm stuff, whatever). The devfs stuff is a kernel compile-time option. make menuconfig -> File Systems -> /dev file system support (EXPERIMENTAL). I would be very leery of turning that on, particularly if the only reason you want it is so that you can specify device numbers instead of device node names on your dasdfmt commands.

I am trying ti use the same procedure that I used for the 2.4.7 kernel. 1.) ICKDSF format the packs, and then CMS format the MDISK areas 2.) echo -n "add device range=204-207">>/proc/dasd/devices 3.) UPDATE zipl.conf and then perform a zipl 4.) I normally would then use dasdfmt -n 204 -b 4096, but that did not work. I noticed in a thread that I should use dasdfmt -f /dev/dasdd -b 4096 This command would allow me to format the dasd. I then went to yast2 to create a LVM. When the system tries to add the dasd to a LVM, it says "pvcreate -- invalid physical volume "/dev/dasdd1" I can issue the pvcreate command pvcreate -ff /dev/dasdd and it says it works. The system seems to have a problem with the numeric part of the dasdx . I tried just formatting the dasd in the partition section but it also has a problem when it tries to format /dev/dasdd1. Is there a setting that needs to be turned on to allow the numerics? Also, someone mentioned that DEVFS needs to be active to use the -n 204 option on a dasdfmt. How is this turned on? Thanks, Ken Vance Amadeus
