Hello, I am also working on the system in question in the original question.
I'm not used to creating or mounting the partitions using the command line options. I do that during the install using the text gui. During that process I partitioned the single dasd for just swap and / . I'd like know what it takes to simply add more and 'tack it on to the end' of the existing partition, if that's even possible. I am able to bring devices online and do the low level format and am able to see the devices in /proc/dasd/devices... But, I could use more detail after that. Thanks for any help you can provide.

If not than first bring them online (chccwdev -e 0.0.XXXX) and then check again. If they are there, than you are ready to do a low level format with dasdfmt /dev/dasdX (/proc/dasd/devices will tell you which dasdX is that). After that, create partitions (or not if you don’t want to) with fdasd /dev/dasdX Later you can create LVM (or not if you don’t want to) with pvcreate, vgcreate, lvcreate. Last step is creating a filesystem with mkfs.ext4 (or ext3) on a new partition or logical volume. And now, you can mount it. But you have to know that at this point you are also rewriting cylinder 0 of this DASD (if it is really attached) so it’s label will change. Let us know if you need more details Grzegorz Powiedziuk > On Aug 6, 2015, at 3:04 PM, Cameron Seay <[email protected]> wrote: > > of course Debian can't see it until it's in a Linux filesystem.
