We're attempting to upgrade all our RHEL6 servers to RHEL7 and have just hit a huge snag that didn't come up in testing (due to our test servers being rebuilt pretty often). All our company-used servers still have LDL formatted minidisks on them, and the upgrade process, at least, doesn't like that one bit--the RHEL7.5 dracut from the RHEL7 ISO can't seem to sense the partitions on them, and thus isn't able to actually use them during the reboot portion of the upgrade. Is there any easy or automated way to convert all the disks of a server to CDL-format (while that server is down, I'm assuming), so we could pop back up and run the upgrade?
I figure given enough time I could somehow script this, but to keep from this project shifting from upgrade-to-RHEL7.5 down to upgrade-to-RHEL6.10, I need to come up with something by Monday. That doesn't feel like enough time. It's definitely not enough time to convince RedHat to update RHEL7 so it continues to recognize LDL-format, even if I can't find anything saying it's no longer supported. I did find plenty saying things like "anaconda no longer supports LDL in RHEL7.1", which is probably about when we changed our kickstarts to start reformatting the z/VM disks before installing RedHat--the reason we didn't see this in test. And it doesn't seem like many folk have been going the upgrade-in-place route on s390x based on other issues we've hit, so that might explain why it doesn't seem to be popping up in current searches. Anyone out there able to grant us a miracle? Thank you! Shannon Collinson | AVP | Infrastructure Operations, Mainframe Engineering SunTrust Bank | Take a step toward financial confidence.
