Don't really see any problems in dmesg. Not sure where to get syslog, there is a /var/log/message, but don't really see anything there. Frank Ramaekers | Senior Systems Administrator | CIS Mainframe Services -Original Message- From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU]

Re: ClefOS will not come up

Much of your console traffic is illegible in the mailing list e-mail and web page, but I can see that you mention z/VM "jerking the rug out from under" your Linux guest. What do you mean? Did you apply maintenance or something? Or did you simply shutdown the guest and now it won't start?

Re: ClefOS will not come up

Well, we were attempting to bring down z/VM 7.2, but some of the virtual machine wouldn't come down. So we forced each of the virtual machine that were still up, then shutdown z/VM. During this process we needed to change the clock, but we inadvertently set the time wrong (off 12 hours...am

Re: ClefOS will not come up

When you logged on the guest did you see any messages pertaining to disks not available? Did the z/VM system come up with all its DASD and if so did they all get attached to the system? Maybe you Linux guest is missing a minidisk or more such that LVM is not able to find everything it needs to

Re: ClefOS will not come up

You should be able to get the system up to network access by using commands. At that point you can use the standard tools to update the configuration files. - Get into maintenance mode using ^D (not sign D on 3270) - Provide root password - cio_ignore -R - chcchwdev -e 0.0.0124 (repeat for other

Re: ClefOS will not come up

You may have added disks to the LV but you cio_ignore settings are stopping them from being seen at IPL. There are a number of ways to avoid this. The hammer approach is to add the devices to your boot parameter "rd.dasd=" but check the other methods. On 2/27/23, 14:44, "Linux on 390 Port on

Re: ClefOS will not come up

No, those parameters are (for ClefOS 7) in /etc/zipl.conf. I use the rd.dasd= mechanism for devices needed for the root file system. Other dasd may be specified in /etc/dasd.conf. Checkout:

Like parameters to the dasd driver. In any event to get going again just use cio_ignore -R to remove the disks from the ignore list and then use chccwdev -e to bring them online. Have pvscan look again to see if it can find things. On 2/27/23, 14:57, "Linux on 390 Port on behalf of Frank M.
