Hi Frank, We have an emergency Linux guest that is able to link minidisks from other guests. So we can link the disk of a guest and then make the required updates with the regular Linux tools (vi or copy files etc). We use this machine also to change a configuration of a cloned guest. Obviously the target must not be logged on otherwise you can't get the disk in write mode. After the update (network, hostname etc) we autolog the guest.
Another way, as you mentioned already, is to use sed in a 3270 console to replace an item in the configuration files. So you could start the guest and then use sed, something like: sed --in-place -e s/10.10.10.10/11.11.11.11/g /etc/sysconfig/network-scripts This can be done in both a regular runlevel or in runlevel 1. I'd say, start your guest without network (detach the vnic), make the update and then restart with full network. Or start your guest and enter "#CP VI VMSG 0 1" to force the guest to start in runlevel 1. (That is, I expect the input in ClefOS is the same as in Suse.) Met vriendelijke groet/With kind regards/Mit freundlichen Grüßen, Berry van Sleeuwen Flight Forum 3000 5657 EW Eindhoven -----Original Message----- From: Linux on 390 Port <[email protected]> On Behalf Of Frank M. Ramaekers Sent: Thursday, 22 July 2021 14:48 To: [email protected] Subject: Recovery assistance. Caution! External email. Do not open attachments or click links, unless this email comes from a known sender and you know the content is safe. I need to recover some files from a FLASHCOPY backup of my ClefOS instance. I'm currently in the process of restoring these to different disk locations. My questions are: 1) How can I bring this new zLinux (VM) up in maintenance mode to change the IP address (in /etc/sysconfig/network-scripts) 2) What method can I use (sed?) to change these ip address since vi doesn't work very well on the VM console for zLinux After I do these, I should be able to bring it up normally and retrieve the programs/scripts/data that I need? Other thoughts?
