Is there a way to restart the loader? When I first connected to the IPLed image I was disconnected before I could do any setup. Now when I login I get a message...
Loader has already been run. Starting shell. If I try to rerun the loader I get the same message. Ruddy A.

I've done several CentOS installations, and I don't recall having to manually format the DASD on any of them... When you SSH/Telnet into the installation system, you end up in the system installer (Anaconda), which is pretty much a bouncing-ball thing, including the setup of the DASD. > It comes back with a message that the file is not available.

It's likely that the installer hasn't set up the device nodes for your DASDs yet -- too early in the piece. > Where does CentOS put the device descriptor and how do I address it in > the 'dasdfmt' command? If you *really* need to format the DASDs manually, you will need to create the device nodes yourself. Check to see that the proc filesystem is mounted, then issue "cat /proc/dasd/devices" to see what device major/minors have been allocated to the DASDs. Then, "mknod /dev/dasd<an> b <maj> <min>" with appropriate substitutions for <an> <maj> and <min>, for each of the nodes you want, will get you started. But you really should not need to do any of this. Just follow the installer's prompts and it should get you there. Rob's comments are gold as well: ensure that the DASDs are online (cat the appropriate "online" pseudofile in the sys filesystem directory you found; a result of "1" is good) and that the DASD modules are loaded.
