 |
|
Hello,
I've tried with both of the s390 and s390x userlands, but had the same outcome on both platforms. I'm trying to follow this guide, but am doing it on a Windows host: https://wiki.gentoo.org/wiki/S390/Hercules (Only differences appear to be networking, which works straight out of the box for me right now).
Booting the system with the following configuration file currently:
| Code: |
#

CPUMODEL 2098 # CPU model number

This is what happens:
- Open up Hercules version 3.12
- ipl from device c
- Linux begins uncompressing, Hercules issues a bunch of CPU messages

- At this point, Hercules goes into a state of 0 MIPS and 0 SIOs. If I issue a command like .help or .passwd, nothing gets output at all. It just returns what I typed either in green text, or not at all.
- If I enter/run the networking commands, it connects and I'm able to SSH in, and acknowledgement messages of that get posted in the Hercules console. However, when trying to get into the root account, the console just returns that the root account is locked, and passwd -l root as well as usermod -U root do nothing/return no output at all.
How can I get this thing up and running? Thanks! |

I have some success with Hercules (Hyperion) 4.0, I have a shell but I am stuck at the step of formatting the dasd:
| Code: |
~ # dasdfmt /dev/dasda
Please enter the blocksize of the formatting [4096]:
dasdfmt: No mount point found for sysfs
|
The boot environment is so minimalist that some really useful commands like strace are missing, so it is somewhat hard to figure out the exact reason, I guess some entry is missing in sysfs or it is not located where it is expected.
FYI, I use:
* netboot-s390x-initramfs-20191211T084703Z
* netboot-s390x-kernel-20191211T084703Z
(Nothing more recent is available for now).
This issue is encountered on the 3-4 available boot images. I cloned the s390-tools Git repo (https://github.com/hreinecke/s390-tools.git), grep ' No mount point found for' returns nothing 
EDIT: recent images are unusable however, there is some old boot images (2016) lying around. like there=> http://62.128.1.45/gentoo/releases/s390/autobuilds
EDIT2: if you have an illegal instruction using wget with hercules, ensure you are using Hercules 4.3. |

I also ran into this problem. It has since been fixed in s390-tools, but there's not a new snapshot with the fix. As a work-around, you can:
# busybox umount /sys # real umount doesn't work due to a missing lib
# mount -t sysfs sysfs /sys # must be sysfs in both places
That should fix the DASD tools. The next thing I ran into is an illegal instruction running env-update. I needed to add this line to my hercules config file to work around that:
FACILITY DISABLE BIT61
I haven't completed a gentoo install yet, but that has gotten me further. I thing the next problem is that the Hercules wiki page has drifted from the Gentoo Handbook. |
