James, If you're still running SuSE 7.0 (2.2.16 kernel) you can _not_ use CDL. That is only supported in the 2.4 kernel series. You can use the mini-HOWTO at file://d:/webpages/linuxvm.org/Info/HOWTOs/movefs.html to copy your data. Once that's done, you will need to re-run silo, pointing to the _new_ IPL volume as it is _currently_ known by the running system, with the parmfile using the _new_ DASD device numbers (in preparation for your next IPL). After that, you should be able to do a shutdown and reboot from the new volume.
You might also want to take a look at file://d:/webpages/linuxvm.org/Info/HOWTOs/dumprest.html for a little explanation of the above, but in the context of using the OFFLINDR program to actually dump the data to tape and back to disk.

IBM has replaced almost 30 disks on the thing since we bought it. They don't want us to have it in the field as it's some how wonky. So they're giving us a new one, and hauling our old one back to the lab. When I first built this one Linux LPAR (SuSE 7.0) I didn't know about CDL. So I used the standard Linux layout. We are unsure whether or not the tool IBM will use can cop non CDL Linux volumes at all. My thought was to re-configure the LPAR with the dasd addresses of the new disk as well as the current disk and just use dd, ( I think?) to copy the volumes and do whatever is necessary with silo to make it so I can IPL from the new DASD. Is there a way to make the new file system CDL and still copy the whole system and make it IPL-able? Is there a way to convert the existing FS to CDL without reformatting?
